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.
A nerve cell has three main components, its dendrites, its soma or body, and. its axon. The dendrites are a tree-like structure that form the main area where. axons of other cells make connections. The connections are anatomically spe-. cialized structures termed synapses (See Figure 3.1). Neurons are unlike other. cells in many ways but ones of the chief diï¬erences is that they are especially.
