C) cell body, dendrites, and axons.
D) transmitters, dendrites, and nodes of Ranvier.

Question

Quizplus · Accepted Answer

The key structural components of neurons are the cell body (which contains the nucleus and other organelles), dendrites (which receive signals from other neurons), and axons (which transmit signals to other neurons). Option A is partly correct but misses out on axons, which are crucial structural components. Option B includes "glands," which are not a structural component of neurons. Option D includes "transmitters" as a key structural component, but transmitters are not a structural component - they are molecules released by neurons to transmit signals. The "nodes of Ranvier" are small gaps in the myelin sheath that cover axons but are not fundamental structural components of neurons.
