Document Summary

Slide 2: objectives: course objective #1: identify the major structures of the cns, neurons, neuroglia, myelin, course objective #4: understand the basics of neural signaling and transmission and identify major transmitters of the cns. Slide 3: structure of the nervous system: macroscopic brain divisions, connecting pathways and cell groupings, receptors and neurotransmitters. Slide 7: multipolar cell multiple dendrites, but only one axon. Conducting zone: axon white matter because myelin. Phospholipid bilayer: can create channel for ions to get in and out of nerve cell. Slide 11: cortical pyramidal cell slide 12: stellate cell ( star ) slide 13: fusiform cell. Axon that leaves the cortex to help communicate with the rest of the body. Slide 14: retinal bipolar cell tapered at both ends big cell body. Only found in cerebellum, has a very large dendritic tree. Just showing one synapse, but there are hundreds. Axon hillock where the axon exits from the cell body.
