PSYC 2015 Study Guide - Final Guide: Ganglion Cell, Nicotinic Acetylcholine Receptor, Gaba Receptor
Document Summary
Types, synthesis, storage, release and regulation of neurotransmitters. Acetyl coenzyme a (from metabolism) + choline (from metabolism/diet) => acetylcholine. Catecholamines: one catechol group and one amine group. Phenylalanine tyrosine dopa dopamine norepinephrine epinephrine. Indole group: mood and sleep, melatonin (indoleamines) Exocytosis: refers to the excretion of the neurotransmitter from the presynaptic terminal into the synaptic cleft. Triggered by an action potential arriving from the axon. Metabotropic receptors (metabolic events include such behaviors as taste, smell, pain) Acetylcholine is broken down by acetylcholinesterase into acetate and choline. Comt: enzymes that convert the excess dopamine into inactive chemicals. Serotonin and catecholamines: detach and transport back. Released peptides trigger other neurons to release same neuropeptide. Diffuse widely and affect many neurons via metabotropic receptors. *small protein-like molecules (peptides) used by neurons to communicate with each other. Endorphin exercise, excitement, pain, spicy food, love, sex.
