PSYC*3150 Lecture Notes - Lecture 3: Axon Terminal, White Adipose Tissue, Acetylcholine
Document Summary
Examples of nts are dopamine, serotonin, and acetylcholine: nts play a role in many disorders such as depression, alzheimer"s, and. Parkinson"s: have most of neurons at birth but continue to make new in adulthood (neurogenesis, while most drugs suppress neurogenesis, cannabis can promote it. Neurons: individual nerve cells that are building blocks of nvs. Dendrites: branch-like structures extending from cell body with receptor sites that are important in neural transmission. Axon: long extension that conducts charge from cell body to axon terminals. Myelin: white fat that covers axons of some neurons. Action potential: electrical impulse on axon that happens when neuron fires. When neuron fires, nts/chemicals released into synapse and influence activity in postsynaptic neurons. Receptor sites: located on dendrites and activated by nts; lock-key analogy. Mimicry: drug with similar chemical structure to a natural nt can bind to receptor sites. Vesicles: tiny sacs in terms that store nts.
