MEDICAL PHYSIOLOGY

Detailed explanation-1: -Dendrites are extensions, or processes, of the cytoplasm that carry impulses to the cell body. An extension or process called an axon carries impulses away from the cell body.

Detailed explanation-2: -Efferent, or motor, nerve fibres carry impulses away from the central nervous system; afferent, or sensory, fibres carry impulses toward the central nervous system.

Detailed explanation-3: -Signals in a neuron move through a synapse, with the help of chemicals called neurotransmitters. A synapse is a place where the signal from one cell is accepted by the axon and is transferred by a branch of dendrites.
