AP PSYCHOLOGY

Detailed explanation-1: -In a neuron, synaptic vesicles (or neurotransmitter vesicles) store various neurotransmitters that are released at the synapse. The release is regulated by a voltage-dependent calcium channel. Vesicles are essential for propagating nerve impulses between neurons and are constantly recreated by the cell.

Detailed explanation-2: -Neurotransmitter is stored inside small sacs called synaptic vesicles, and is released into the synaptic cleft of the synapse when a vesicle fuses with the cell membrane.

Detailed explanation-3: -Synaptic vesicles (SVs) are small, electron-lucent vesicles that are clustered at presynaptic terminals. They store neurotransmitters and release them by calcium-triggered exocytosis. SVs are made locally at the terminals and are regenerated after exocytosis.

Detailed explanation-4: -’ Synaptic Vesicles: small secretory vesicles that contain a neurotransmitter, are found inside an axon near the presynaptic membrane, and release their contents into the “synaptic cleft” after fusing with the membrane.
