Where would you see the nodes of Ranvier?
- A. on an axon
- B. in the cell body
- C. on a dendrite
- D. a and c
Correct Answer: A
Rationale: Nodes of Ranvier are small gaps in the myelin sheath along the axon of a neuron. They play a critical role in the rapid conduction of electrical signals, as the action potential 'jumps' from one node to the next in a process called saltatory conduction. This increases the speed and efficiency of neural communication. Nodes of Ranvier are essential for proper nerve function and are found exclusively on axons.
The hypothalamus contains cells which are sensitive to:
- A. PO2
- B. arterial blood pressure
