Which item is NOT listed as a part of a nerve cell?

Explanation:
Neurons have defined structural features that relate to their function: dendrites receive signals, the nucleus houses the cell’s genetic material, and the myelin sheath insulates the axon to speed up signal transmission. A ribosome is a cellular machinery for protein synthesis found in many cell types, including neurons, but it isn’t described as a specific structural part of a nerve cell in basic neuroanatomy. Because ribosomes aren’t a distinctive nerve-cell component like dendrites, nucleus, or myelin sheath, it’s the answer that doesn’t fit as a listed part of a nerve cell.
