If you think of the brain as a central computer that controls all the functions of your body‚ then the nervous system is like a network that relays messages back and forth from it to different parts of the body. It does this via the spinal cord‚ which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part. When a message comes into the brain from anywhere in the body‚ the brain tells the body how to react. For example‚ if you accidentally

The divisions of the nervous system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The CNS is made of two parts the brain and the spinal cord. The PNS is made up the Somatic nervous system and the automatic system. The somatic nervous contains the peripheral nerve fibers that deliver sensory information to the CNS and motor nerve fibers that go to the skeletal muscle. The central nervous system sends messages from the brain to the rest of the body. (Divisions of The

Anatomy & Physiology P5‚ M2 & D2: Explain the concept of homeostasis and discuss the probable homeostatic responses to changes in the internal environment during exercise In this assignment the concept of homeostasis will be explained and the probable homeostatic responses to changes in the internal environment during exercise will be discussed. Homeostasis is simply how the body keeps conditions inside the same. It is described as the maintenance of a constant internal environment.

Pathophysiology of Multiple Sclerosis Multiple sclerosis (MS) is a chronic inflammatory autoimmune demyelinating disease of the central nervous system‚ affecting the brain and spinal cord. MS affects approximately 400‚000 people in the United States alone. The onset of MS is usually between 20 and 40 years of age and is more common in women; men may have a more severe progressive course (Luzzio‚ 2013). Life expectancy is shortened in persons with MS‚ and the survival rate is linked to disability

CM is a congenital anomaly in which parts of the brain protrude through the opening in the base of the skull into the spinal column. Chiari used to be considered a rare disorder‚ although‚ due to advances in modern technology‚ it is said that there is more people diagnosis. One in one thousand children‚ approximately‚ are born with this disorder every year.

Abstract Approximately 11‚000 spinal cord injuries involving Paraplegia are reported in the United States yearly. These injuries occur as a result of automobile and motorcycle accidents‚ falls‚ sporting accidents‚ and gunshot wounds; although‚ it is also caused by congenital conditions. When the spinal nerve signals below the level of the injury is partially cut off from the brain‚ this results in Paraplegia disability. This is an impairment of motor or sensory function of the lower extremities
