ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).

Detailed explanation-3: -Cyton is a part of neuron containing the nucleus. It is also called cell body.

Detailed explanation-4: -The cell body houses the production center of a cell. Inside the cell body is the nucleus, which contains the cell’s DNA and the genetic information on how to make all of the proteins that a cell needs. The rest of the cell body contains the cytoplasm, a gelatinous substance that surrounds the nucleus.

Detailed explanation-5: -Thus, each nerve cell has a cell body containing a nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, and other organelles that are essential to the function of all cells (Figure 1.3).
