Anatomy Of A Nerve

The sciatic nerve is a peripheral nerve. They serve as information pipelines that allow the brain and spinal cord to communicate with other tissues and organs.

A nerve is an enclosed cable like bundle of axons the projections of neurons in the peripheral nervous system pns.

Anatomy of a nerve. Nerve structure anatomy nerves are the organs that make up the peripheral nervous system pns. Inside the nerves groups of neurons nerve cells are organized into bundles called fascicles fasciculi. Nerve impulses or action potentials are electrochemical impulses that cause neurons to release electrical or chemical signals that initiate an action potential in another neuron.

A nerve provides a structured pathway that supports the electrochemical nerve impulses transmitted along each of the axons. Spinal nerves innervate distribute tostimulate much of the body. The sciatic nerve controls sensation and movement of the leg and foot anatomy.

Nerve impulses are received at neuronal dendrites passed through the cell body and are carried along the axon to the terminal branches. The trigeminal nerve roots and ganglion like those of other cranial nerves are located right outside the brainstem. Cranial nerves innervate parts of the head and connect directly to the brain.

Nervous system the nervous system has two major parts. The central system is the primary command center for the body and. Nerves can be categorized into two groups based on where they connect to the central nervous system.

The brainstem is the lower part of the brain that serves as the physical connection between the spinal cord and the cerebral cortex of the brain. The sciatic nerve controls most movement and sensation throughout the leg and foot.
