The Myelin Sheath is Formed By

Question

The myelin sheath is formed by:
A)Nissl bodies.
B)nodes of Ranvier.
C)Schwann cells.
D)neuron cell bodies.

Accepted Answer

The myelin sheath is formed by Schwann cells in the peripheral nervous system, while it is formed by oligodendrocytes in the central nervous system. Nissl bodies are found in neuron cell bodies and are involved in protein synthesis. Nodes of Ranvier are the gaps between the myelin sheaths where the axon is exposed. Neuron cell bodies are the main part of the neuron that contains the nucleus and other organelles.
