24 de oct. de 2023 · Peripheral nerves. The workhorse of the peripheral nervous system are the peripheral nerves.Each nerve consists of a bundle of many nerve fibers and their connective tissue coverings. Each nerve fiber is an extension of a neuron whose cell body is held either within the grey matter of the CNS or within ganglia of the PNS. The comparable structure of the CNS is called a ‘tract’.
Your nervous system, which consists of your brain, spinal cord, peripheral nerves and autonomic nerves, coordinates all movements, thoughts and sensations that you have. In this article, we'll examine the structure and functions of your nervous system, how nerve cells communicate with each other and various tissues and what can go wrong when nerves become damaged or diseased.
30 de oct. de 2023 · Nerves are the functional and structural units of the peripheral nervous system (PNS). They are composed of groups of individual specialized cells called neurons (or nerve cells), which transmit motor and sensory information back and forth between the PNS and central nervous system (CNS). Transmission is initiated via electrochemical impulses ...
Nerves are the organs that make up the peripheral nervous system. It consists of a cord-like structure with multiple nerve fibres (also called axons) wrapped in layers of tissue and fat. This axon has layers of connective tissue around it. This connective tissue is called the endoneurium. This entire nerve is further enclosed in another layer ...
The cervical plexus is composed of axons from spinal nerves C 1 through C 5. It branches into nerves in the posterior neck and head as well as the phrenic nerve, which connects to the diaphragm at the base of the thoracic cavity. Figure 12.4.5 12.4. 5: Nerve Plexuses of the Body.
