The region of the neuron containing the nucleus is known as the cell body, soma, or perikaryon (Figure 8.2). The cell body is the metabolic center of the neuron.
What is cell body and its function?
Cell body. Also known as a soma, the cell body is the core section of the neuron. The cell body contains genetic information, maintains the neuron’s structure, and provides energy to drive activities. Like other cell bodies, a neuron’s soma contains a nucleus and specialized organelles.

What is a cell body quizlet?
Cell Body. The cell body, also called the soma, is the spherical part of the neuron that contains the nucleus and holds all of the general parts of the cell. The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.
