B. hyper polarization
C. Repolarization

3. As an action potential progresses, the permeability to Na+ decreases and the permeability to _____ increases.
A. Ca2+
B. K+
C. Na+

4. The period of time when the neuron is totally insensitive to further stimulation and cannot generate another action potential is.
A. Absolute refractory period
B. repolarization
C. threshold

5. What muscle and nerve will you need to isolate to study the physiology of nerve fibers?

This completes the physio ex 9.0 exercise 3 questions I need answers to for neuophysiology of nerve impulses.

Ps. I also need answer key to the lab computer simulation portion as well. Anything anyone can do to help me. I need ASAP in pdf or answer written. Thanks biology forum folks.
