Synaptic vesicles contain neurotransmitter, which activates the post-synaptic neuron.
Receptors activate the neuron when neurotransmiters bind to it.
Reserve receptors are kept in the synapse. The synapse can move them to the membrane during learning.
The synaptic cleft is the space between the synapse. It allows for neurotransmitter to move to the other side.
The ER stands for endoplasmic reticulum. It is an internal storage of the cell. It stores calcium ions.
Mitochondria make the energy for the synapse.
Calcium channels are activated by action potentials and trigger the release of neurotransmitters.
Kinases move around the synapse to change how everything works.
