In the context of communication in the nervous system, neurotransmitters bind to the __________ to initiate communication.

• A. myelin sheath
• B. receptors on the postsynaptic membrane
• C. axon hillock
• D. nodes of Ranvier

Answer: (B)

Verified step by step guidance

1. Understand that neurotransmitters are chemical messengers released from the presynaptic neuron into the synaptic cleft.
2. Recognize that for communication to continue, neurotransmitters must bind to specific sites on the receiving neuron.
3. Identify that these specific sites are called receptors, which are located on the postsynaptic membrane of the receiving neuron.
4. Recall that the myelin sheath, axon hillock, and nodes of Ranvier have different roles in nerve signal transmission but are not the binding sites for neurotransmitters.
5. Conclude that neurotransmitters bind to receptors on the postsynaptic membrane to initiate communication between neurons.
