MEDICAL PHYSIOLOGY

Detailed explanation-1: -The region of the neuron containing the nucleus is known as the cell body, soma, or perikaryon (Figure 8.2).

Detailed explanation-2: -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).

Detailed explanation-3: -Most neurons have a cell body, an axon, and dendrites. The cell body contains the nucleus and cytoplasm. The axon extends from the cell body and often gives rise to many smaller branches before ending at nerve terminals. Dendrites extend from the neuron cell body and receive messages from other neurons.

Detailed explanation-4: -A neuron has three basic parts: a cell body, and two branches called an axon and a dendrite. Within the cell body is a nucleus, which controls the cell’s activities and contains the cell’s genetic material. The axon looks like a long tail and sends messages from the cell.
