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.

Anatomy of a nerve. The sciatic nerve controls most movement and sensation throughout the leg and foot. Spinal nerves innervate distribute tostimulate much of the body. A nerve is an enclosed cable like bundle of axons the projections of neurons in the peripheral nervous system pns.

The trigeminal nerve roots and ganglion like those of other cranial nerves are located right outside the brainstem. They serve as information pipelines that allow the brain and spinal cord to communicate with other tissues and organs. Nerves can be categorized into two groups based on where they connect to the central nervous system.

A nerve provides a structured pathway that supports the electrochemical nerve impulses transmitted along each of the axons. Inside the nerves groups of neurons nerve cells are organized into bundles called fascicles fasciculi. Cranial nerves innervate parts of the head and connect directly to the brain.
