PSY290H5 Lecture Notes - Lecture 3: Resting Potential, Schwaan, Reuptake
Document Summary
Introduction to today"s class (not apart of slides) The two major categories of cells: neurons, glia have the capacity to produce neurotransmitters, but more involved in support activity and functioning of neurons. Basic unit of the nervous system (peripheral nervous system) Function: allow for communication (within psn as well as cns) Three main functions: reception receiving information from another cell, conduction involves changes that occur within the neuron itself, transmission taking the information and moving it one way or another. Communication: chemical in the form of neurotransmitters, electrical allow for chemical information to occur. Excitation increasing likelihood of action potential occurring. Inhibition decrease the likelihood of action potential occurring: axon terminal (terminal button) Allows for entry or exit of various kinds of chemicals into the cell. Made up of phospholipid bi- layer (2 layers made of lipids and phosphates) Rely on channels to gain entry or exit of the cell.
