Document Summary

The same hormones may have different effects on target cells. 2 main parts cns (central nervous system) Animals have complex nervous systems which consists of. Cns where integration takes place; brain and nerves. Pns brings info into and out of cns. Ion pumps and channels maintain the resting potential of a neuron. Every cell has a voltage across its plasma called a membrane called membrane potential. Messages are transmitted as changes in membrane potential. Sodium potassium pump channel protein that makes na+ and k+ using atp. Most voltage-gated channels are closed, some k+ are open. When action potential is generated, voltage-gated na+ open first that allows na+ to flow into the cell. During the rising phase the threshold is crossed and membrane potential is increased. During the falling phase, voltage-gated na+ channels become inactivated, voltage-gate k+ channels open and k+ flow out of the cell.
