Anatomy is the branch of biology concerned with the study of the structure of animals and their parts; it is also referred to as zootomy to separate it from human anatomy. In some of its facets, anatomy is related to embryology and comparative anatomy, which itself is closely related to evolutionary biology and phylogeny.[1] Human anatomy is one of the basic essential sciences of medicine.

The discipline of anatomy is divided into macroscopic and microscopic anatomy. Macroscopic anatomy, or gross anatomy, is the examination of an animal’s body parts using unaided eyesight. Gross anatomy also includes the branch of superficial anatomy. Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures, known as histology and also in the study of cells.

The history of anatomy is characterized by a progressive understanding of the functions of the organs and structures of the human body. Methods have also improved dramatically, advancing from the examination of animals by dissection of carcases and cadavers (corpses) to 20th century medical imaging techniques including X-ray, ultrasound, and magnetic resonance imaging.

...As far as we know, anatomy is the oldest medical science. Cave paintings of the early Stone Age, about 30,000 years ago,* show a simple knowledge of the anatomy of animals, and it is assumed that these cave dwellers applied some of their anatomical knowledge to their own bodies. The civilizations of the Babylonians, as Syrians, Egyptians, Chinese, and Hindus made no serious attempt to learn anatomy because they were interested in the supernatural world, not the natural one, and their cultures placed strong religious restrictions against debasing the body. Any anatomical dissections that were performed on animals were made to "study" organs in an effort to predict the future and to tell fortunes. *The Stone Age, the earliest known period of human culture, is characterized by the use of small stone tools. Anatomy in Ancient Greece The systematic study of anatomy may have begun in the fifth century B.C ., with the work of two Greek scientists, Alcmaeon (ca. 500 B.C.) in Italy andEmpedocles (ca. 490-430 B.C) in Sicily, where Greek culture and science flourished. Alcmaeon was probably the first person to dissect the human body for research purposes, and he is also given credit for proposing that the brain is the center of intelligence. Empedocles, who believed that the heart distributed life-giving heat to the body, initiated the idea that an ethereal substance called pneuma, which was both life and soul, flowed through the blood vessels. Although such early anatomists were often...

Anatomy and Physiology

...Summary Week 1 Discussion This discussion we looked at two examples of the heart and its functions. Atrial septal defect (ASD) is fairly common. This was a terrific example to relate structure and function. When the structure of anatomy is disrupted we can see as in this example how normal function is altered. This congenital defect allows blood to flow between atria instead of the normal flow through the ventricles and to the body and the disrupted and limited blood flow can lead to heart failure, stroke and pulmonary hypertension. The larger the hole the more quickly surgery is needed to correct it. Smaller holes may provide enough blood flow to avoid these complications and may heal over on its own. Ventricular septal defect (VSD) is less common. A hole between the ventricles allows mixing of oxygenated blood from the lungs with de-oxygenated blood returning from the body. Heart failure and infections occur rapidly due to the lack of oxygenated blood reaching the body and the baby often presents with a bluish discoloration to the skin as a result of lack of oxygen. Artificial hearts being developed run on batteries to pump the blood and include porting valves to ensure blood flow goes in the correct direction. Essential characteristics of an artificial heart that would make them ideal would be to mimic the real heart in structure and function and resist rejection in the recipient.

Anatomy and Physology

...Osteoporosis is a disease where decreased bone strength increases the risk of a broken bone. It is the most common reason for a broken bone among people who are old. Bones that commonly break include the back bones, the bones of the forearm, and the hip. Until a broken bone occurs there are typically no symptoms. Bones may weaken to such a degree that a break may occur with minor stress or spontaneously. Chronic pain and a decreased ability to carry out normal activities may occur following a broken bone. Postmenopausal osteoporosis is the most common form of osteoporosis. It affects many women after menopause, leaving some women up in age such as an 84 year old slim, small boned female at high risk for fracture. Osteoarthritis is a type of joint disease that results from breakdown of joint cartilage and underlying bone. The most common symptoms are joint pain and stiffness. Initially, symptoms may occur only following exercise, but over time may become constant. Other symptoms may include joint swelling, decreased range of motion, and when the back is affected weakness or numbness of the arms and legs. The most commonly involved joints are those near the ends of the fingers, at the base of the thumb, neck, lower back, knees, and hips. Joints on one side of the body are often more affected than those on the other. Usually the problems come on over years. It can affect work and normal daily activities. Unlike other types of arthritis, only the joints are typically affected. ...

...Lewis: Human Anatomy and Physiology, 12th ed. Chapter 1: Introduction to Human Anatomy and Physiology Chapter 1: Introduction to Human Anatomy and Physiology I. Introduction A. The interests of our earliest ancestors most likely concerned injuries and illness because healthy bodies demand little attention from their owners. B. Primitive people certainly suffered from occasional aches and pains, injuries, bleeding, broken bones, and diseases. C. Before agriculture, infectious diseases did not spread easily because isolated bands of people had little contact with each other. D. With agriculture, humans became susceptible to worm diseases because excrement was used in fertilizers and less reliance was placed on wild plants that offered their protective substances. E. With urbanization, humans became more susceptible to infectious diseases and malnutrition. F. Tooth decay was lowest among hunter-gathers and highest among city residents. G. Preserved bones from children can reflect malnutrition because when a child starves or suffers from severe infection, the ends of the bones stop growing. When health returns, growth resumes, but leaves behind areas of dense bone. H. At first healers had to rely on superstitions and notions about magic. I. The forerunners of modern drugs were herbs and potions. J. Early medical providers developed the language of anatomy and physiology from Greek and Latin. II. Anatomy and Physiology A.

Anatomy I

...Sarahbeth Cook May 12, 2011 Anatomy I Professor Kriota Willberg It is rare to find someone with a complete and perfect symmetrical body. Every human being has his or her own skeletal structure and no one is alike. If you are one of those few people lucky enough to have “perfect symmetry and balance,” you might end up finding a flaw elsewhere, or so I’d like to think. For myself, being as active of a dancer that I am, I already put a tremendous amount of wear and tare on my body, especially since I’ve been studying for eighteen years. The chances of me being perfectly in balance are slim to none. No matter how much physical therapy I do on my body, if I continue to dance with extreme physical motion I will always have something that is not in place. After doing these assessments I discovered a few things I didn’t realize about my body, but after analyzing them I see how they possibly may trigger some of my areas of discomfort. These imbalances affect my everyday activities, physical comfort, range of motion, and general sense of well-being. I have the privilege of having a physical trainer to assist me at work before every performance. She’s there to make sure my imbalances are cared for and I’ve been given exercises to strengthen my weak areas. The main areas I’ve decided that need major work consist on my shoulders, spine, core, and ankle/foot. I’ve selected a series of exercises that I believe will help improve my weaknesses. My overall posture is very good and that...

Reflection on Intro to Physiology/Anatomy

...We started with the introduction to anatomy by defining it as the scientific discipline that investigates the structure of the body. I have discovered that there are two basic approaches to the study of anatomy are systematic (by system) and regional (by area), the latter which is more commonly used in most medical schools. And of course studying the structure is not enough, this is where physiology comes in which is the scientific discipline that deals with the processes or functions of living things. I have known homeostasis as the maintenance of the relatively constant environment in the body but it is only now that I have learned about positive and negative feedback mechanisms which maintain homeostasis and that positive homeostasis can be detrimental at times. I’ve also learned more on the anatomical terms that will be used throughout our course and maybe even in med school. In the study of cells, I was able to recall the things we have discussed in our biological science course in the previous year. I remember the three types of solution namely hypotonic, isotonic, and hypertonic. I also come to know more about the different movements across the cell membrane. However I was new to the transcription and translation that happens in the gene expression of a cell. I was able to associate codons of the mRNA strand with the anticodon of the tRNA. Similar to cytology, I was also able to look back on our discussions about tissues last year. I have refreshed myself on the...

Sc121 Unit 1 Lets Talk Anatomy

...Let’s talk anatomy Anatomy is the science of body structures and the relationships among them. It is all around us, it is basically us. The human anatomy deals with basically all the parts of humans, dealing with molecules to bones to the way we function, but that can also get misinterpreted for Physiology which is the study of body functions and how the body parts work, which in this case it is something different. Anatomy and Physiology are two concepts that are related to each other, as stated before anatomy is the science of body structures and the relationship among them, while Physiology is the study of body functions and how body parts work together. Now, with all of that being said Anatomy differs from physiology in many ways, the study of anatomy usually focuses on the shape, size, and where they are usually located at. In my perspective anatomy is more like dissection of the body, you can easily cut up the body and with your very own eyes see what the body is, or in more scientific forms using a microscope for a more detailed view. A person can easily see what they are encountering on a body and what system is connected to what. In physiology its rather more vigorous mostly involving different types of properties (chemical, physical or electrical) that make the body function. Beginning from the process of how our heart rate is regulated to more difficult systems involving different visual perceptions. Physiology is usually involved with the work of living...
