What is the outer nervous system?
The peripheral nervous system (PNS) is the division of the nervous system containing all the nerves that lie outside of the central nervous system (CNS). The primary role of the PNS is to connect the CNS to the organs, limbs, and skin.
What is nervous system made up of?
The nervous system is made up of the central nervous system and the peripheral nervous system: The brain and the spinal cord are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.
What are the 2 sides of the nervous system?
It has two main parts: the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system (all the other nerves in your body).
What makes up the peripheral nervous system of the body?
The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body. The nervous system transmits signals between the brain and the rest of the body, including internal organs.
What is the outer layer of the nervous system called?
Each nerve has a protective outer layer called myelin. Myelin insulates the nerve and helps the messages get through. Peripheral nervous system: Your peripheral nervous system consists of many nerves that branch out from your CNS all over your body.
What makes up the central nervous system CNS?
Central nervous system (CNS): Your brain and spinal cord make up your CNS. Your brain uses your nerves to send messages to the rest of your body. Each nerve has a protective outer layer called myelin. Myelin insulates the nerve and helps the messages get through.
What are the non neuronal parts of the nervous system?
The electrical signal then travels through the neuron and goes through the same conversion processes as it moves to neighboring neurons. The nervous system also includes non-neuron cells, called glia (pronounced GLEE-uh). Glia perform many important functions that keep the nervous system working properly.
