Which structure is the main site of communication between a neuron and its target cell?
Correct answer: B. Synaptic cleft
- A. Cell body
- B. Synaptic cleft
- C. Myelin sheath
- D. Axon hillock
Explanation
The synaptic cleft is the narrow gap across which neurotransmitters diffuse between cells. The axon hillock helps initiate impulses, while myelin insulates the axon rather than transmitting signals between cells.

About Nervous System and Special Senses
The nervous system covers neurons, neuroglia, nerve impulses, synapses, reflex arcs, and the organization of the central and peripheral nervous systems. It also explains the autonomic divisions and the receptors and pathways for vision, hearing, balance, taste and smell, distinguishing sensory reception from conscious perception.
