What is the job of the central nervous system (CNS)? The central nervous system consists of the brain, the spinal cord, and a complex network of neurons. They are protected by the meninges which are three layers of connective tissue and the central nervous system is also encased in bone while being surrounded by cerebrospinal fluid which also adds an additional protection from injury. The brain is our central control center that processes many body functions and sensory information whereas the spinal cord is a conduit for communication between the brain and the rest of the body. The spinal cord is also responsible for controlling certain simple musculoskeletal reflexes that do not need input from the brain. The brain processes both conscious and unconscious body functions. Neurons are the basic unit of nervous tissue that is responsible for transmitting signals. So the neurons receive information from the body which then it travels up the spinal cord into the brain where it can be processed. (a.u., www.mcb.berkeley.edu) What is the job of the peripheral nervous system (PNS)? The peripheral nervous system works with the central nervous system where it is the rest of the nervous system throughout the body which includes the senses of vision, hearing, taste and smell as well. It also includes the automatic nervous system that controls such actions as digestion and temperature control, the involuntary control of muscles whereas the voluntary control of skeletal muscles is the somatic system. The motor nervous system is part of the PNS where it carries information to the organs, muscles, and glands from the CNS. (a.u., 2008) Basically the PNS carries all the information for the entire body back and forth through the CNS by way of neurons. When eating ice cream too quickly it can result in brain freeze where the blood vessels in the roof of the mouth...

The Human Body's Nervous System

...* What is the job of the central nervous system (CNS)? The central nervous system, also known as the CNS, consists of three(3) major components of the human body: * Brain – the brain is made up of three(3) parts: the cerebrum, the diencephalon, and the hindbrain. * Nerve Tissue – this part of the CNS is comprised of neurons, synapses, and neurotransmitters. * Spinal Cord – protected by vertebrae in the back, the spinal cord is made up of fiber tracts and spinal nerves. (Pedersen DD; PsychNotes: Clinical Pocket Guide, 3rd ed, F.A. Davis Company, 2011, Ch. 9, pg. 1) One of the two major divisions of the human body’s nervous system, the central nervous system is responsible for integrating sensory information and responding accordingly. In other words, its job is to get information from the body and send out instructions to the body. * What is the job of the peripheral nervous system (PNS)? The peripheral nervous system, or PNS, is made up of two(2) components of the human body: * Afferent System – this system is made up of somatic and visceral sensory neurons. * Efferent System – this part of the PNS controls the somatic nervous system (somatic motor neurons), as well as the parasympathetic nervous system, both of which are made up visceral motor neurons.

Biological Basis of Behaviour

...of our thinking, feeling, and acting is the nervous system. The nervous system is the physiological network of intercommunicating cells that forms the basis of our ability to perceive, adapt to, and interact with the world. The brain is the supreme organ of the nervous system and it is the organ that most directly controls our thoughts, emotions, and motivations. The Organization of the Nervous System The Central Nervous System (CNS) o The nervous system consists of two main parts, the central nervous system (CNS) and the peripheral nervous system. o The central nervous system has two parts: the brain and the spinal cord. Both parts are encased in bone for protection and further protected from shocks by cerebrospinal fluid which circulates throughout the brain and the spinal cord. o The brain responds to information it receives from the rest of the body. Communication within the brain is two-way; (1) the brain receives and processes information and (2) then forwards the information with instructions on how to respond. o In the brain, a network of individual cells called neurons receives information and transmits it to the spinal cord. The spinal cord is a slender, roughly cylindrical rope of interconnected fibers, enclosed within the spinal column, that transmit information from sensory neurons to the brain and from the brain to motor neurons. o One function of the spinal cord is to collect information from the peripheral nervous system and transmit it to the brain and back......

Tour of the Brain

...College Author Note This paper is being submitted on XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX General Psychology. A Tour of the Brain The brain is the control center of the human body. It is protected by the skull and is made up of three main parts, the cerebrum, the cerebellum and the Brainstem. The brain is the boss of the body, it runs the show and controls just about everything one does, even when one’s asleep. (Kidshealth, n.d.) During this brief tour guide of the brain, one will see how the brain fits into the Central Nervous System, how the main parts work together, and what would happen if one of those main parts were damaged. In humans, the nervous system is divided into the central nervous system (CNS), which consist of the brain and spinal cord, and the peripheral nervous system (PNS), which contains all the nerves that run everywhere in the body. The brain and the spinal cord serve as the main processing center for the entire nervous system, and control all the workings of the human body. They work together to let messages flow back and forth between the brain and the body. The biggest part of the brain is cerebrum. The cerebrum is the thinking part of the brain and it controls the voluntary muscles, the ones that move when you want them to. When one is thinking hard, trying to solve a math problem or trying to figure out a video game, one is using the cerebrum. (Kidshealth, n.d.) The cerebrum is made up two sides, the left and right hemispheres. The......

...My job in the medical field that I picked is a neurosurgeon. A neurosurgeon is a surgeon that operates on the central nervous system. The central nervous system (or CNS for short) is made up of the spinal cord and brain, the two nerve transfer areas in our bodies. The spinal cord is very important, if it's damaged you can become paralyzed, meaning you lose all feeling and motion in that area of your body. There is many different parts of being paralyzed. There is paraplegic, meaning you lose feeling and motion of your legs. There is also tetraplegic meaning you lose feeling and motion of your arms. There is many more types of paralias but my job as a neurosurgeon is to do my best to repair the spinal cord as quickly and as efficiently as I...

Why Do You Get Goosebumps

... Most animals regulate their body temperature at a particular level. For humans it is 37°C. If the temperature is too high the body will apply different mechanisms to decrease its temperature. E.g. sweating and dilation of blood vessels. If the temperature is to low the body will counteract to increase the temperature. E.g. shivering, constriction of blood vessels and goose bumps. This is a negative feedback system which allows us to maintain homeostasis. Homeostasis is the process of keeping a constant internal condition. How do we keep things the same? To keep our body at a constant temperature we need three things: receptors, a processing centre and effectors. Thermoreceptors in the skin detect changes in external temperature. They pass this information on to the processing centre in the brain called the hypothalamus which is a tiny gland in the brain. An important job of the hypothalamus is to regulate body temperature. Your body’s reaction to heat loss is involuntary and controlled by the hypothalamus. When it receives the message from the thermoreceptors it automatically triggers changes to effectors. The effectors are tiny muscles called arrector pili found attached to the hair follicles. When stimulated, these muscles will contract and cause the...

Worldwide, it affects about 2.5 million people (NewsRx Health and Science, 2012). Its exact cause is unknown, however the common thought is some unknown virus or gene defect is the blame. To really understand Multiple Sclerosis we will need to look at it definition and history, the statistics of number people afflicted with it, what are the social-psychological challenges of the disease. We will also need to look at what kind of research projects and experiments have been done regarding the disease, what kind of help and support that the community have to offer to its patients, and the interventions impact on MS.

It warms and moistens the air before it reaches the lungs, and helps remove unwanted particles, like dust and soot. | Trachea | The trachea is also known as the windpipe. It is a bony tube, which connects the nose and mouth to the lungs, hence is an important part of the respiratory system in vertebrates | Lungs | The lungs take in oxygen, which the body's cells need to live and carry out their normal functions. The lungs also get rid of carbon dioxide, a waste product of the cells. | Nervous system Brain | The brain is like a central computer that control bodily functions. It is protected by the skull to reduce damage. It is divided into many parts, including the cerebrum and brain stem. It stores and sorts out information before sending out any necessary commands. It is the centre of control and its job would be incomplete without the spinal cord. | Nerves | Each nerve is connected to a particular area and is responsible for connection to and from different regions of the body. ‘Multiple sclerosis’ is a problem which can damage nerves and prevent signals to travel from them. | Spinal cord | The spinal cord is a long bundle of nerve tissues. It is protected by the vertebrae so it doesn’t get damaged. There is also fluid that helps protect nerve tissue, keeping it healthy by removing waste products.

Fetal Alcohol Syndrome

...Running Head: FETAL ALCOHOL SYNDROME 1 FETAL ALCOHOL SYNDROME 2 Fetal alcohol syndrome (FAS) is the most recognizable form of fetal alcohol spectrum disorders (FASD). FAS is characterized by a pattern of minor facial anomalies, prenatal and postnatal growth retardation, and central nervous system abnormalities. Those born with FAS often have behavioral and learning difficulties. The consequences of the damages caused by the mother's drinking is lifelong (Wattendorf & Muenke, 2005). To date, there has been no extensive population-based studies done (Vaux & Chambers, 2012). However, data in one sample demonstrated that approximately 1 in 100 children have alcohol-related effects. In high-risk pregnancies, predicted incidences of fetal alcohol syndrome are approximate and differ because of varied definitions of heavy drinking and inconsistent methods of diagnosis. For this reason, rates range from 4% to as much as 44%.The estimation of FAS in the United States is 1-2 cases per 1000 live births (Wattendorf & Muenke, 2005) . Fetal alcohol exposure is the leading known cause of mental retardation in the Western world. The term Fetal Alcohol Syndrome was first published in a 1973 article in the British medical journal......

Alcohol and Its Effects

...cardiomyopathy, liver disease and the increase of unemployment from excessive alcohol drinking. Today alcohol counts for a large percentage of accidents and deaths among people each year and is responsible for half of all accidental deaths and suicides. It has always been evident that alcohol has an effect on brain function. Alcoholism and binge drinking are the leading cause of death in America, and according to the National Institute on Alcohol Abuse and Alcoholism (NIAAA) about two thirds of men and about one half of women in America drink alcohol. And aside from intoxication, drinking alcohol can cause memory loss, seizures, headaches, and blackouts. While all body systems feel the affect of alcohol, the CNS (central nervous system) is particularly sensitive. Science Net Link states alcohol as a depressant of the CNS, that makes nerve cells in the brain less excited causing them to slow down. Science Net Link also points out that alcohol affects our brain’s chemistry as well by altering levels of neurotransmitters, which are the chemical messengers that transmit signals throughout the body to control our thoughts, behavior, and emotions. Dr. George Kruick on Healthline.com states that drinking too much could also alter levels of certain nutrients in the body, which includes...
