What is the control center of the Schwann cell?

• A. Schwann cell nucleus
• B. Rounded areas on the end of the axon terminals
• C. Terminal branches
• D. Aqueous humor

Answer: (A)

The nucleus serves as the control center for a Schwann cell because it contains the cell’s DNA and coordinates gene expression and protein synthesis. This lets the Schwann cell regulate its metabolism, respond to signals, and produce the myelin components necessary for insulating peripheral nerves. The other options don’t fit: rounded areas at the end of axon terminals are synaptic boutons involved in neurotransmitter release, not a cell’s command center; terminal branches are parts of the neuron, not the Schwann cell’s control hub; aqueous humor is a fluid in the eye, unrelated to Schwann cell function.
