Activity at an axon terminal: Neuron A is transmitting a signal at the axon terminal to neuron B (receiving). Features: 1. Mitochondrion. 2. synaptic vesicle with neurotransmitters. 3. Autoreceptor. 4. Synapse with neurotransmitter released (serotonin). 5. Postsynaptic receptors activated by neurotransmitter (induction of a postsynaptic potential). 6. Calcium channel. 7. Exocytosis of a vesicle. 8. Recaptured neurotransmitter. |
An amino acid neurotransmitter is an amino acid which is able to transmit a nerve message across a synapse. Neurotransmitters (chemicals) are packaged into vesicles that cluster beneath the axon terminal membrane on the presynaptic side of a synapse in a process called endocytosis.[1] Amino acid neurotransmitter release (exocytosis) is dependent upon calcium Ca2+ and is a presynaptic response. There are inhibitory amino acids (IAA) or excitatory amino acids (EAA). Some EAA are L-Glutamate, L-Aspartate, L-Cysteine, and L-Homocysteine.[2] These neurotransmitter systems will activate post-synaptic cells.[3] Some IAA include GABA, Glycine, β-Alanine, and Taurine.[2] The IAA depress the activity of post-synaptic cells.[3]
