Receptor sites for neurotransmitters are present on the:
Correct answer: C. Postsynaptic membrane
- A. Presynaptic membrane
- B. Tips of axons
- C. Postsynaptic membrane
- D. Membranes of synaptic vesicles
Explanation
A neurotransmitter is a chemical substance responsible for the transmission of nerve impulses across a synapse. It is released by the synaptic vesicle into the synaptic cleft. The neurotransmitter binds with protein receptor molecule present on the postsynaptic membrane causing its depolarization and generation of an action potential.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
