ANATOMY

Detailed explanation-1: -Bundle of neurons is called a nerve. Sensory neurons bundle together to form sensory nerve. Motor neurons bundle together to form motor nerve. These neurons help in transferring impulses from the central nervous system (CNS) to other parts of the body and vice versa.

Detailed explanation-2: -Each bundle of nerve fibers is called a fasciculus and is surrounded by a layer of connective tissue called the perineurium. Within the fasciculus, each individual nerve fiber, with its myelin and neurilemma, is surrounded by connective tissue called the endoneurium.

Detailed explanation-3: -A typical neuron has several dendrites, normally arranged in an extremely branched fashion, in order to establish contacts with many other neurons. The cell body also known as the soma which includes the nucleus and perikaryon.

Detailed explanation-4: -A nerve is a bundle of nerve fibres.
