PSY290H5 Chapter Notes - Chapter 4: Membrane Potential, Neurotransmitter, Exocytosis
Document Summary
Electrical signals are turned into chemical signals at synapses. Exogenous means arising from outside the body. Presynaptic is a term that refers to something located on the transmitting side of a synapse. Postsynaptic means located on the receiving side of a synapse. Synapse is the cellular location at which information is transmitted from a neuron to another cell. Exocytosis is a cellular process that results in the release of a substance into the extracellular space. Neurotransmitter receptors are specialized proteins that are embedded in the cell membrane, allowing it to selectively sense and react to molecules of the corresponding neurotransmitter. Amino acid neurotransmitters are neurotransmitters that are themselves an amino acid (like gaba, glycine, and glutamate) Peptide neurotransmitters is a neurotransmitter consisting of a short chain of amino acids. Amine neurotransmitters are based on modifications of a single amino acid nucleus (like serotonin, and dopamine) Gas neurotransmitters are soluble gases (like nitric oxide and carbon monoxide)
