Cholesterol is needed by the nervous system to insulate neurons and prevent damage that would interfere with the normal function of the nervous system.
Calcium also plays an important role in the central nervous system, especially within the brain. Calcium ions are essential in converting electrical impulses into chemical signals in the brain. The presence of calcium ions in the synaptic vesicles triggers the neurotransmitters to be released into the synaptic cleft. The signal can then cross the cleft and fuse with the dendrite on the other side, effectively helping to pass the signal to wherever it needs to go in the brain.

∙ 14y agoWe have a nervous system to keep us from killing ourselves. If you walked on a hot sidewalk and didn't have a nervous system, you would destroy your feet. If you gripped a tool bar, you wouldn't know how hard to grip it because you couldn't feel it. If you sat on a hill in the summer time, you wouldn't feel the sun, the grass, or the wind. If God hadn't given us a nervous system, it would be a terrible world. If we did have a nervous system (Wich we Do) We could be happy! (And we are, some people anyway)☺☻

∙ 13y agoThe Nervous System is necessary because without it no part of the human body can exist. It maintains homeostasis (makes sure all other systems are working). The human body cannot exist without it.

What role does the nervous system play in the digestive system?
The digestive system is related to the nervous system in such a way that the nervous system dictates the speed of breaking down of food. The nervous system overseas activity in the digestive tract, and regulates secretion if there are changes.
Does the central nervous system consist of the somatic nervous system?
No. Nervous System is comprised of the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) The PNS is comprised of the Somatic Nervous System and the Autonomic Nervous System The Autonomic Nervous System is comprised of the Sympathetic Nervous System, the Parasympathetic Nervous System and the Enteric Nervous System
What comprises the nervous system?
The Sympathetic Nervous System and the Parasympathetic Nervous System
The portion of the nervous system away from the central nervous system?
peripheral nervous system
The cranial and spinal nerves form what nervous system?
the peripheral nervous system
What are the two types of nervous system?
They are the central nervous system and the periperhal nervous system.but in the periperhal nervous system ,they are two nervous system divided，。
The somatic nervous system is a component of what nervous system?
peripheral nervous system
Is autonmic nervous system apart of the peripheral or central nervous system?
The autonomic nervous system is a division of the central nervous system.
Which system or systems are necessary for walking and running?
Cardiovascular, Respiratory, Nervous, Skeletal systems are use in running and walking
What are two main jobs of the nervous system?
The nervous system takes in sensory information from the peripheral nervous system. This information is then directed to the central nervous system which then responds with a motor reaction that travels back to the peripheral nervous system.
What nervous system innervates cardiac and smooth muscles and glands?
They are controlled by the autonomous nervous system.== ==
