Synaptic vesicles are structures __________.
A) in which transmitters are stored
B) from which axon collaterals extend
C) in the shape of bulbs that protrude into the synaptic gap
D) found in the postsynaptic membrane

Question

Quizplus · Accepted Answer

Synaptic vesicles are small, spherical structures located within the axon terminal of a neuron. They contain neurotransmitters, which are released into the synaptic cleft when an action potential reaches the axon terminal. Therefore, choice A is the correct answer as it accurately describes the function of synaptic vesicles. Choice B is incorrect because axon collaterals are extensions of the axon, not synaptic vesicles. Choice C is incorrect because it describes the shape of synaptic vesicles but does not accurately describe their function. Choice D is also incorrect because synaptic vesicles are located in the presynaptic membrane, not the postsynaptic membrane.
