Nerves are like cables that carry electrical impulses between your brain and the rest of your body. These impulses help you feel sensations and move your muscles.
nerve, in anatomy, a glistening white cordlike bundle of fibres, surrounded by a sheath, that connects the nervous system with other parts of the body. The nerves conduct impulses toward or away from the central nervous mechanism.
A complex system of nerves and muscles enables the human eye to blink, gaze, and shift focus. The trochlear nerve is one of six cranial nerves that carry electrical impulses from the brain to the eye.
Nerves are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body. Each axon is wrapped in a connective tissue sheath called the endoneurium.
Specific terms are used to describe nerves and their actions. A nerve that supplies information to the brain from an area of the body, or controls an action of the body is said to innervate that section of the body or organ.
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).
Several cranial nerves and most spinal nerves are involved in both the somatic and autonomic parts of the peripheral nervous system. Spinal nerves emerge from the spinal cord through spaces between the vertebrae.
