BIO 1012 Week 8 Assignment 2 Neurophysiology of Nerve Impulses Recent

OBJECTIVES

1.       To define the following terms:irritability, conductivity, resting membrane potential, polarized, sodium-potassium pump, threshold stimulus, depo- larization, action potential, repolarization, hyperpolarization, absolute refractory period, relative refractory period, nerve impulse, compound nerve action potential, and conduction velocity.

2.       To list at least four different stimuli capable of generating an action potential.

3.       To list at least two agents capable of inhibiting an action potential.

4.       To describe the relationship between nerve size and conduction velocity.

5.       To describe the relationship between nerve myelination and conduction velocity.
