SCI227 Lecture Notes - Lecture 18: Myelin, Micrograph, Schwann Cell
Document Summary
General outcome: students will explain how the nervous system controls physiological processes. Nervous system: describe the organization of the peripheral nervous system in terms of motor, sensory-somatic, sympathetic and parasympathetic. Identify the cell body, dendrite, axon, schwann cell, myelin sheath, node of ranvier, and synaptic knob a neuron on a prepared slide or photomicrograph. Sketch and label a graph of the polarity of a neuron membrane during the transmission of a nerve impulse, including the retting potential, action potential, and refractory period. Infer from data that effects of common stimulants, depressants, or other chemicals on excitatory, and inhibitory responses of neurons. Identify the motor cortex and sensory cortex on a model or diagram of the brain: design an experiment to investigate the reflex arc. Perform an experiment to measure an individual"s ability to visually discriminate objects. Perform an experiment to measure and individual"s ability to hear a range of sounds.
