Color blindness or color vision deficiency is the inability or decreased ability to see color, or perceive color differences, under lighting conditions when color vision is not normally impaired. "Color blind" is a term of art; there is no actual blindness but there is a fault in the development of one or more sets of retinal cones that perceive color in light and transmit that information to the optic nerve

Muscular dystrophy (MD) is a group of muscle diseasesthat weaken the musculoskeletal system and hamper locomotion.[1][2] Muscular dystrophies are characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells andtissue.[3]

Blood disorders can lead to poor blood clotting and continuous bleeding. The disorders can result from defects in the blood vessels or from abnormalities in the blood itself, such as in blood clotting factors or in platelets.

Ichthyosis (plural ichthyoses) is a heterogeneous family of at least 28,[1] generalized, mostly genetic skindisorders. All types of ichthyosis have dry, thickened, scaly or flaky skin.[1] In many types there is cracked skin,[2] which is said to resemble the scales on a fish; the word ichthyosis comes from the Ancient Greek ιχθύς (ichthys), meaning "fish.

In general variables from the same group of subjects, & you are trying to determine if there is a relationship (or covariation) between the 2 variables (a similarity between them, not a difference between their means). Theoretically, any 2 quantitative variables can be correlated (for example, midterm scores & number of body piercings!) as long as you have scores on these variables from the same participants; however, it is probably a waste of time to collect & analyze data when there is little reason to think these two variables would be related to each other

50 The metencephalon is a developmentalcategorization of portions of the central nervous system. The metencephalon is composed of the ponsand the cerebellum; contains a portion of the fourth ventricle; and the trigeminal nerve (CN V), abducens nerve (CN VI), facial nerve (CN VII), and a portion of thevestibulocochlear nerve (CN VIII).
The midbrain or mesencephalon (from the Greekmesos - middle, and enkephalos - brain[1]) is a portion of the central nervous system associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation.[2]

medula
The inner core of certain organs or body structures, such as the marrow of bone. Also calledmedullary substance.

The cerebellum (Latin for little brain) is a region of thebrain that plays an important role in motor control

The thalamus (from Greek θάλαμος = room, chamber) is a midline paired symmetrical structure within thebrains of vertebrates, including humans

The hypothalamus (from Greek ὑπό = under andθάλαμος = room, chamber) is a portion of the brain that contains a number of small nuclei with a variety of functions.

amygdala; also corpus amygdaloideum; Latin, from Greekαμυγδαλή, amygdalē, 'almond', 'tonsil', listed in theGray's Anatomy as the nucleus amygdalæ)[1] are almond-shaped groups of nuclei located deep within themedial temporal lobes of the brain in complex vertebrates, including humans.

The hippocampus is a major component of the brains ofhumans and other vertebrates

The cerebrum or telencephalon, together with thediencephalon, constitutes the forebrain. The cerebrum is the most anterior (or, in humans, most superior) region of the vertebrate central nervous system.

The corpus callosum (Latin: tough body), also known as the colossal commissure, is a wide, flat bundle of neural fibers beneath the cortex in the eutherian brainat the longitudinal fissure.

51.The frontal lobe is located at the front of the brain and is associated with reasoning, motor skills, higher level cognition, and expressive language. At the back of the frontal lobe, near the central sulcus, lies the motor cortex. This area of the brain receives information from various lobes of the brain and utilizes this information to carry out body movements. Damage to the frontal lobe can lead to changes in sexual habits, socialization and attention as well as increased risk-taking.

• The parietal lobe is located in the middle section of the brain and is associated with processing tactile sensory information such as pressure, touch, and pain. A portion of the brain known as the somatosensory cortex is located in this lobe and is essential to the processing of the body's senses. Damage to the parietal lobe can result in problems with verbal memory, an impaired ability to control eye gaze and problems with language.

• The temporal lobe is located on the bottom section of the brain. This lobe is also the location of the primary auditory cortex, which is important for interpreting sounds and the language we hear. The hippocampus is also located in the temporal lobe, which is why this portion of the brain is also heavily associated with the formation of memories. Damage to the temporal lobe can lead to problems with memory, speech perception and language skills.

• The occipital lobe is located at the back portion of the brain and is associated with interpreting visual stimuli and information. The primary visual cortex, which receives and interprets information from the retinas of the eyes, is located in the occipital lobe. Damage to this lobe can cause visual problems such as difficulty recognizing objects, an inability to identify colors and trouble recognizing words.

PET scan

A positron emission tomography (PET) scan is an imaging test that uses a radioactive substance called a tracer to look for disease in the body.

The CAT scan tends to be completely painless, though it may require people to lie still for a period of time. Depending on the area for which one is having a CAT scan, the patient may have to fast for four to six hours prior to the scan. This is particularly the case if one is having an abdominal/pelvic scan. In this case, one may also be asked to drinkbarium, a substance that shows up on the scan to identify any trouble or blockages in the intestines.

An MRI (magnetic resonance imaging) scan is a imaging test that uses powerful magnets and radio waves to create pictures of the body. It does not use radiation (x-rays).

Pituitary gland
53. A small organ at the base of the brain, the pituitary gland is a very powerful component of the endocrine system. Not much bigger than a pea, the pituitary gland secretes and produces many different hormones that not only regulate important biochemical processes, but also govern the behavior of other glands.

hormone • Prolactin -- The primary functions of prolactin are to stimulate the production of breast milk following childbirth and to regulate sex hormone levels in both men and women. • Growth hormone (GH) -- This hormone produced by the pituitary gland promotes growth in children. Too much growth hormone in children can create a condition known as acromegaly or gigantism. In adults, growth hormone helps to maintain muscle and bone mass as well regulate fat distribution. • Adrenocorticotropin (ACTH) -- This hormone stimulates production of the “stress hormone”, cortisol, produced by the adrenal glands and is responsible for maintaining optimal blood pressure and glucose levels. • Thyroid-stimulating hormone (TSH) -- This hormone governs vital processes and systems, such as energy, growth, metabolism and the nervous system by stimulating the thyroid gland. Variations in these levels could be the result of thyroid problems such as an overactive thyroid or an underactive thyroid. (You can learn more about each of those at our Thyroid Problemspage. • Antidiuretic hormone (ADH) -- Also known as vasopressin, this hormone’s function is to regulate the balance of water in the body. When levels of antidiuretic hormone are not where they should be, it can lead to conditions such as diabetes insipidus and syndrome of inappropriate ADH, both of which affect the kidneys. • Luteinizing hormone (LH) -- This hormone regulates levels of testosterone by the testes and estrogen by the ovaries in men and women, respectively. • Follicle-stimulating hormone (FSH) -- Working with luteinizing hormone, follicle-stimulating hormone promotes normal functioning of the ovaries and testes by regulating sperm production and ovulation in men and women, respectively.

Parathyroid gland: A gland that regulates calcium, located behind the thyroid gland in the neck. The parathyroid gland secretes a hormone called parathormone (or parathyrin) that is critical to calcium and phosphorus metabolism. Although the number of parathyroid glands can vary, most people have four, one above the other on each side. They are plastered against the back of the thyroid and therefore at risk for being accidentally removed during thyroidectomy.

the hormones of pancreas insulin, glucagon, and somatostatin.

The pancreas is a small organ, approximately six inches long, located in the upper abdomen, and adjacent to the small intestine. It lies toward your back. Because it is so deep within your body, doctors have difficulty diagnosing disease in the pancreas.

Causes of Disease

...Causes of disease A disease is defined as a physical or mental disorder or malfunction with a certain set of signs or symptoms. Diseases may be caused by a single factor such as a pathogenic microorganism or have many causes some of which may depend on lifestyle. Pathogens have many qualities that assist with the causing of diseases: they can gain entry to the host, colonise tissues of the host, resist defences of the host and cause damage to the host’s tissues. Microorganisms gain entry to the host through the skin and through exchange sites. For example, if someone has physical contact with an infected individual. All these characteristics lead to a disease occurring in the host. Some examples of pathogens are bacteria, viruses and fungi. A healthy lifestyle involves, maintaining a healthy weight, taking regular exercise, eating a balanced diet, drinking a limited amount of alcohol and not smoking. If individuals lead a healthy lifestyle, the risk of contracting a disease will decrease. For example, the carcinogenic chemicals found in tobacco smoke may increase an individual’s risk of contracting cancer. However, people need to remember that it’s never too late to change your lifestyle. For example, there is clear evidence showing that the risk of lung cancer to a smoker is reduced if they stop smoking. Going into more detail about the pathogen, we can understand what consequences the production of toxins can cause. A toxin is a harmful chemical that......

Causes Of Alzheimer's Disease

...Alzheimer’s disease is a specific sort of neurological disorder that impairs memory and tampers with various other integral mental functions. Similar to disorders of the like, Alzheimer’s is a progressive disease, essentially intensifying in severity as time continues. In 1999, approximately four million geriatrics in America alone were diagnosed with Alzheimer’s. Even with these staggeringly high numbers, the rate of incidence for the disease shows no signs of decelerating as experts expect this statistic to triple to by the year 2020 (Altman 9). The reason for this trend may lie in the most common cause of Alzheimer’s itself: old age.

The Cause Of Alzheimer's Disease

...Even though the cause of Alzheimer’s is yet to be discovered it is known that patients experiencing this disease exhibit two distinct changes in the brain; plaque and tangles. Plaques are made of a protein called beta-amyloid that builds into small clumps in the cortex of the brain that intermingles with the function of nerve cells ( Alzheimer's Disease). Once these nerve cells become affected, the patients gradually begin to change moods and personality. At first it can be difficult to recognize the subtle changes because one might be stereotypical and assume that age is the cause of crankiness or fatigue. Everyday tasks became harder to accomplish as the patient becomes unable to recognize how to go forth with these actions.At this point...

Causes of Cardiovascular Disease

...Causes of cardiovascular disease While cardiovascular disease can refer to many different types of heart or blood vessel problems, the term is often used to mean damage caused to your heart or blood vessels by atherosclerosis (ath-ur-o-skluh-RO-sis), a buildup of fatty plaques in your arteries. This is a disease that affects your arteries. Arteries are blood vessels that carry oxygen and nutrients from your heart to the rest of your body. Healthy arteries are flexible and strong. Over time, however, too much pressure in your arteries can make the walls thick and stiff — sometimes restricting blood flow to your organs and tissues. This process is called arteriosclerosis, or hardening of the arteries. Atherosclerosis is the most common form of this disorder. Atherosclerosis is also the most common cause of cardiovascular disease, and it's often caused by an unhealthy diet, lack of exercise, being overweight and smoking. All of these are major risk factors for developing atherosclerosis and, in turn, cardiovascular disease Symptoms of heart disease in your blood vessels (cardiovascular disease) Cardiovascular disease is caused by narrowed, blocked or stiffened blood vessels that prevent your heart, brain or other parts of your body from receiving enough blood. Cardiovascular disease symptoms can include: * Chest pain (angina) * Shortness of breath * Pain, numbness, weakness or coldness in your legs or arms, if the blood vessels in those parts of your body......

Alzheimer’s disease is a progressive, degenerative, disease that affects the brain and can also profoundly affect you or someone you love. Alzheimer’s disease is a degenerative disorder that attacks the brain’s nerve cells or neurons. The neurons slowly break their connections with other nerve cells and then begin to slowly die, resulting in memory loss, behavioral changes, and loss in thinking and language skills (About Alzheimer’s, Definition of Alzheimer’s 1).

The Cause Of Alzheimer's Disease

...Although the cause of Alzheimer’s disease isn’t completely understood, two major factors that are connected to the progression are plaques and tangles. In the cell membrane of a neuron in the brain, you have an molecule called amyloid precursor protein, or APP. One end of the amyloid is in the cell, while the other is out. Scientists believe that this helps the neuron grow and repair itself after an injury. Since APP is a protein, it gets used and over time gets broken down and recycled. Normally it gets chopped up by enzymes called alpha secretase and gamma secretase. This chopped up protein dissolves over time. If another enzyme, beta secretase teams up with gamma secretase, then we have a problem. This piece cannot dissolve and creates...

Cancer Is A Disease: The Cause Of Cancer

...Cancer is a disease in which cells grow out of control and invade, erode, and destroy normal tissue. It has sadly affected many people. Damaged genes are the cause of this. Since mitosis - a process for cell division - and the cell cycle are controlled by genes, having damaged genes can cause the cell to go wrong. If it starts in just a single cell, it can replicate itself to make new cells that duplicate. In the cell cycle, cells can be in the G1 or G0 stage. Often cells leave G1 and enter G0 where they carry out their functions then die out or re-enter the cell cycle if needed. It is usually a balance.

Major and Minor Causes of Heart Disease

...Heart disease affects so many people that it has become a serious concern about medical science. The heart is a complex organ that is vulnerable to hereditary as well as environmental risks. Cardiologists think of these risk factors as either major or minor causes of heart disease. There are several major and minor causes of heart disease. The first major cause of heart disease is family history. Family history risk is included people’ DNA because if one of your siblings has had a heart attack, that gives you higher risk than if one of your relatives has heart related problem. Also the other major cause is high blood pressure because the heart works too hard, so it damage arteries. When it damages arteries, damaged arteries can not deliver enough oxygen to other parts of body. In addition to high blood pressure can damage brain. Furthermore, high cholesterol levels cause heart disease as well. It is dangerous because fatty deposits build up in blood vessels.
