Document Summary

Module 3. 1: neurons and behavior: types of cells in the nervous system, 1. Glia: type of cell that supports the neurons by insulating them, synchronizing activity among neighboring neurons, and removing waster products (neural. Nannies: smaller but more abundant than neurons, neurons consists of 3 parts, 1. Cell body: contains the nucleus of the cell: 2. Dendrites: widely branching structures that receive input from the other neurons: 3. Resting potential (axon isn"t stimulated) an electrical polarization across the membrane of an axon- salty banana: sodium-potassium pump: pushed the sodium ions out of the axon and pulls in the potassium ions in. Different ways action potential starts: many axons produce spontaneous activity. Small places of healthy tissue can function, even though unable to give conscious perception: 2. Sympathetic nervous system: controlled by a chain of cells lying just outside the spinal cord, increases heart rate, breathing rate, sweating, and other processes that are important for fight-or-flight activities: 2.
