The region of cytoplasm close to the nucleus, rich in components for protein synthesis, is termed perikaryon. Additionally, dendrites are shorter, tapering, and extensively branched structures, and both are exclusive to nerve cells.

1. Perikaryon
2. Dendrites
3. Both
4. Neither

Correct answer: Both

Solution

Both perikaryon and dendrites are structural components of nerve cells. The perikaryon surrounds the nucleus and contains organelles for protein synthesis, while dendrites are branched processes that receive signals.
