What is the compact area of a nerve cell that contains the nucleus and surrounding cytoplasm, excluding the axon and dendrites?

What is the compact area of a nerve cell that contains the nucleus and surrounding cytoplasm, excluding the axon and dendrites?

• A. Cell body
• B. Axon
• C. Dendrite
• D. Nucleus

Answer: (A)

The stage being tested is the neuron's structure and which region contains the nucleus along with the surrounding cytoplasm, while excluding the axon and dendrites. That region is the cell body, also called the soma. It is the metabolic center of the neuron, housing the nucleus and most organelles (like the Golgi and mitochondria) within the cytoplasm. The nucleus sits inside this area, but the nucleus alone wouldn’t account for the surrounding cytoplasm and organelles that define the cell body. The axon and dendrites are separate processes: the axon transmits signals away from the cell body, and dendrites receive signals. So the compact area that contains the nucleus and surrounding cytoplasm is the cell body.
