NEET BIOLOGY

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 cell body (soma or perikaryon) contains the nucleus and other cell organelles. There are clusters of rough endoplasmic reticulum (not shown in Figure 1) that are called Nissl bodies or are sometimes referred to as chromatophilic substances.

Detailed explanation-3: -The soma (tree trunk) is where the nucleus lies, where the neuron’s DNA is housed, and where proteins are made to be transported throughout the axon and dendrites. There are different types of neurons, both in the brain and the spinal cord.

Detailed explanation-4: -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).
