Figure 1: Summary of sympathetic (A) and parasympathetic (B) autonomic neural outflows from the central nervous system. Figure drawn by the authors, incorporating material from Gray's Anatomy 31st Edition 1954, and from Cannon and Rosenblueth Physiology of the Autonomic Nervous System, 1937.
A typical neuron consists of a cell body (soma), dendrites, and an axon.The term neurite is used to describe either a dendrite or an axon, particularly in its undifferentiated stage.ynaptic signals from other neurons are received by the soma and dendrites; signals to other neurons are transmitted by the axon. A typical synapse, then, is a contact between the axon of one neuron and a dendrite or soma of another.
They communicate with one another, with cells in the sensory organs, and with muscles and glands. Each neuron has the same structure: 1  Each neuron has a soma, or cell body, which is the central area of the neuron.2  It contains the nucleus and other structures common to all cells in the body, such as mitochondria.hey communicate with one another, with cells in the sensory organs, and with muscles and glands.
