Detailed explanation-1: -axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe.
Detailed explanation-2: -An axon is a thin fiber that extends from a neuron, or nerve cell, and is responsible for transmitting electrical signals to help with sensory perception and movement. Each axon is surrounded by a myelin sheath, a fatty layer that insulates the axon and helps it transmit signals over long distances.
Detailed explanation-3: -Typical neurons have several dendrites-branching processes that conduct impulses toward the cell body, and a single axon-a long straight process that conducts impulses away from the cell body. Axons are often referred to as nerve fibers.
Detailed explanation-4: -Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands. Efferent neurons usually have short dendrites and long axons.
Detailed explanation-5: -The function of the axon is to transmit information to different neurons, muscles, and glands.
