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: -Nerve. 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-3: -Bundle of neurons is called a nerve. Sensory neurons bundle together to form the sensory nerve. Motor neurons bundle together to form the motor nerve.
Detailed explanation-4: -THe nerve cells are also known as neurons. The neurons consist of long and thin projections. The projections are known as the axons. The nerves fibres are arranged in the form of bundles.
Detailed explanation-5: -They usually are arranged haphazardly throughout the perikaryon of neurons but are aligned longitudinally in axons and dendrites.
