Which structure of the neuron contains the nucleus?

• A. Dendrites
• B. Cell body
• C. Axon
• D. Myelin sheath

Answer: (B)

Nucleus location in neurons. The nucleus acts as the cell’s command center, housing the genetic material and directing activities like protein synthesis. In neurons, it sits in the cell body (the soma), which is the metabolic hub of the cell. Dendrites are the branched structures that receive signals, and the axon transmits those signals away from the cell body. The myelin sheath surrounds the axon to speed signal conduction but does not contain the nucleus. So, the structure that contains the nucleus is the cell body.
