Detailed explanation-1: -A nerve contains bundles of nerve fibers, either axons or dendrites, surrounded by connective tissue. Sensory nerves contain only afferent fibers, long dendrites of sensory neurons. Motor nerves have only efferent fibers, long axons of motor neurons. Mixed nerves contain both types of fibers.

Detailed explanation-2: -A nerve is an enclosed, cable-like bundle of nerve fibers (called axons) in the peripheral nervous system. Axons transmit electrical impulses. Nerves have historically been considered the basic units of the peripheral nervous system.

Detailed explanation-3: -What are nerves? 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. They also maintain certain autonomic functions like breathing, sweating or digesting food.

Detailed explanation-4: -A nerve fibre, also called an axon, is a long and slender projection of nerve cells (or neurons) that carry electrical impulses away from the nerve cell body. A neuron typically has one nerve fibre emanating from its cell body that transmits impulses to other neurons, muscles or glands.
