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 neuron consists of two major parts: a cell body and nerve processes. Cell Body. Neurons contain the same cellular components as other body cells. The central cell body is the largest part of a neuron and contains the neuron's nucleus, associated cytoplasm, organelles, and other cell structures. The cell body produces proteins needed for the construction of other parts of the neuron. Nerve Processes. Nerve processes are finger-like projections from the cell body that are able to conduct and transmit signals. There are two types: Axons: typically carry signals away from the cell body. They are long nerve processes that may branch out ...
