What is the main difference between the central nervous system and the peripheral nervous system?

What is the main difference between the central nervous system and the peripheral nervous system?

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.

What is the difference between the CNS and the peripheral nervous system quizlet?

the CNS is the control center, brain and spinal cord. The PNS is nerve fibers that carry information to and from the CNS. White matter is myelinated fibers and is in the inside of the brain and outside of spinal cord.

What is the role of the peripheral nervous system?

The PNS has three basic functions: (1) conveying motor commands to all voluntary striated muscles in the body; (2) carrying sensory information about the external world and the body to the brain and spinal cord (except visual information: the optic nerves, which convey information from the retina to the brain, are in …

What is central system?

What is the central nervous system? The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.

What are the two types of peripheral nervous system?

The peripheral nervous system is divided into two main parts:

• Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
• Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.

What is peripheral nervous system function?

What is central nerve system?

What is central nervous system?

What does peripheral nervous system do?

What makes up the peripheral nervous system?

The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

What are the two types of peripheral nerves?

Why is the PNS important?

PNS comprises of nerves and neurons outside of brain and spinal cord. They coordinate with the central nervous system in receiving and sending the messages. Unlike brain and spinal cord, the nerves of PNS are not protected in any cavity or membranes, which is why peripheral nervous system is more vulnerable to develop toxic and mechanical injuries.

What are the similarities between CNS and PNS?

Here are some key similarities and differences when comparing the CNS (Brain & spinal cord) and PNS (somatic/autonomic & sympathetic/parasympathetic). Similarities: The brain stem and spinal cord both control involuntary processes (e.g. the brain stem controls breathing and the spinal cord controls involuntary reflexes).

What are the major parts of the peripheral nervous system?

General Nerve Structure. The peripheral nervous system is made of nerves,ganglia,and plexuses.

Cranial Nerves. The PNS can be said to consist of 12 pairs of cranial nerves and 31 pairs of spinal nerves.

Spinal Nerves. There are 31 pairs of spinal nerves,arising from different regions of the spinal cord.

What nerves are involved in the peripheral nervous system?

Branches of the cervical and lumbosacral spinal nerves anastomose peripherally into plexuses, then branch into nerve trunks that terminate up to 1 μm away in peripheral structures. The intercostal nerves are segmental. The term peripheral nerve refers to the part of a spinal nerve distal to the nerve roots.
