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 (/ËnjÊÉrÉn/ NYEWR-on or /ËnÊÉrÉn/ NEWR-on; also known as a neurone or nerve cell) is an electrically excitable cell that processes and transmits information through electrical and chemical signals. These signals between neurons occur via synapses, specialized connections with other cells.Neurons can connect to each other to form neural networks. Neurons are the core components of the brain and spinal cord of the central nervous system (CNS), and of the ganglia of the peripheral nervous system (PNS).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. Synaptic signals may be excitatory or inhibitory.
