ANATOMY

Detailed explanation-1: -The axon arises from the soma at a region called the axon hillock, or initial segment. This is the region where the plasma membrane generates nerve impulses; the axon conducts these impulses away from the soma or dendrites toward other neurons.

Detailed explanation-2: -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-3: -When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite.
