MCB 32 F09 Chapter 7: Neuronal action potentials and synaptic transmission pp. 160-166, 170-184, 196-198 Study Guide Define : central and peripheral nervous systems; sensory and motor nerves; Schwann and oligodendrocytes; glial cells; threshold of action potential; overshoot; refractory period; voltage-dependent Na channel; activation and inactivation of Na channel; voltage-dependent K channel; conduction of action potential; myelin; synapse; synaptic vesicle; acetylcholine; acetylcholine receptor; hyperpolarize vs depolarize; excitatory and inhibitory post synaptic potentials Distinguish: Properties of action potentials vs. synaptic potentials – graded vs. all or none, ion channels involved, depolarization vs hyperpolarization. Relative vs. absolute refractory period. Sensory vs. motor nerve. Autonomic nerve to viscera vs. motor nerve to skeletal muscle. 1. T-F? The supporting cells that form myelin in the peripheral nervous system are called glial cells. 2.
