What is the physiology of the nervous system?
Physiology of the nervous system is the study of the human nervous system. Nervous is composed of two main parts: central nervous system (CNS) and peripheral nervous system (PNS). CNS and PNS cooperate through a system of neurons that spread throughout the body. The physiology of the nervous system also concerns disorders of the nervous system that occurs due to injury or disease. The combined efforts of the nervous system physiologists have led to new treatment of these disorders. Six hundred years later, the Roman physician Galen made a more accurate conclusion by saying that the brain was the nerve control center because they eventually led all the nerves. Over the next 1,400 years, many thinkers, including Leonardo da Vinci, contributed to the physiology of the nervous system. Only 20 centuries were able to find the internal functioning of the nervous system first.
as Galen suggested in the second century, the brain isthe key to the nervous system of the body. IT and spinal cord are part of CNS. The spinal cord sends sensory information to the brain processing centers. The reaction of the brain, usually instructions to move the body in some way, is sent to the respective muscles. Because CNS is necessary for human life, the brain and spinal cord are protected by bones from injury; The protective membrane known as meninges blocks some viruses, bacteria and foreign substances.
The peripheral nervous system is all nerves outside the brain and spinal cord. One feeling of touch stems from them. Although these nerves are not protected by bones or meninges, they have the ability to partially regenerate and/or recover if damage should occur. VPNS, sensory neurons pass information about brain and backbone chord. Motor neurons transmit the brain instructions to muscles.
The peripheral nervous system is further divided into a somatic and autonomous nervous system. The somatic nervous system is groups of neurons that provide muscle control. The autonomic nervous system is groupsand neurons that perform unconscious brain functions: digestion, heart rate, sweating, etc.
In addition to studying the function and structure of the nervous system, the nervous system physiology also includes nervous system disorders. For example, meningitis ignites meninges covering the brain and spinal cord. Spinal cord injury can cause loss of feeling and paralysis. Scientists studying nervous system disorders and the physiology of the general nervous system have led to more effective treatment to prevent paralysis after the spine trauma. For example, methylprednisolone, if administered intravenously to eight hours of injury, shows a certain success in preventing spinal cord damage.
