2023年4月5日 · The soma, or cell body, is where the signals from the dendrites are joined and passed on. The soma and the nucleus do not play an active role in the transmission of the neural signal. Instead, these two structures serve to maintain the cell and keep the neuron functional.
Soma (biology) - New World Encyclopedia
Soma is the bulbous body of a neuron (nerve cell) from which one or more processes emanate (dendrites and/or axons) and which is the part of the neuron that contains the cell nucleus enclosing a conspicuous nucleolus.

2023年12月21日 · The cell body of a neuron, also known as the soma, is typically located at the center of the dendritic tree in multipolar neurons. It is spherical or polygonal in shape and relatively small, making up one-tenth of the total cell volume.
Nerve Cell Body | Complete Anatomy - Elsevier
The nerve cell body (often called perikaryon or soma), houses a large, spherical, euchromatic nucleus with a prominent nucleolus, and cytoplasm. The size of cell bodies varies depending on the type of neuron and can range from 5-140 μm (Marieb, Wilhelm and Mallatt, 2012).
