Study Notes
Synaptic Vesicles and Neurotransmitters
- Synaptic vesicles in the presynaptic terminal contain neurotransmitters that are released into the synaptic cleft.
Synaptic Cleft
- The synaptic cleft is the small gap between the presynaptic and postsynaptic neurons, where neurotransmitters are transmitted.
Receptors and Neurotransmitters
- Receptors on the postsynaptic membrane bind to neurotransmitters released from the presynaptic terminal.
Neurotransmitter Release
- Voltage-gated calcium channels within the presynaptic terminal trigger the release of neurotransmitters into the synaptic cleft.
Neurotransmitter Function
- The main role of neurotransmitters is to transmit signals from the presynaptic neuron to the postsynaptic neuron.
Axon Terminal
- The axon terminal of the presynaptic neuron contains synaptic vesicles that store neurotransmitters.
Synaptic Gap
- The synaptic cleft separates the presynaptic and postsynaptic membranes.
Receptor Location
- Specialized receptors that bind to neurotransmitters are located on the postsynaptic membrane.
Neurotransmitter Release Trigger
- Voltage-gated calcium channels trigger the release of neurotransmitters into the synaptic cleft.
