Study Notes
Synaptic Components
-
Synaptic Vesicles: Small membrane-bound sacs that store neurotransmitters, essential for transmitting signals across a synapse.
-
Synaptic Cleft: The tiny gap between the presynaptic neuron and the postsynaptic neuron, where neurotransmitters are released and bind to receptors.
-
Presynaptic Neuron: The neuron that releases neurotransmitters into the synaptic cleft upon receiving an action potential, facilitating communication between neurons.
-
Postsynaptic Neuron: The neuron that receives neurotransmitters from the synaptic cleft, where chemical signals convert into electrical impulses.
-
Axon Terminal: The endpoint of a neuron where synaptic vesicles are concentrated, and neurotransmitter release occurs into the synaptic cleft.
-
Vesicle Releasing Neurotransmitter: The process by which synaptic vesicles fuse with the presynaptic membrane and release their contents into the synaptic cleft, crucial for neuronal communication.
