An action potential is regarded as an example of a positive feedback. Which of the following examples below best illustrates the positive feedback aspect of an action potential?
◦ Voltage gated potassium ion channels open slowly and remain open long enough to cause hyperpolarization.
◦ Potassium permeability is about 25 times greater than sodium ions.
◦ A threshold stimulus will cause the opening of voltage gated sodium ion channels that will cause further depolarizing stimulus. This stimulus will open still more voltage gated sodium ion channels.
◦ The sodium potassium pump consistently moves ions as long as ATP is available, and regardless of membrane potential changes.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
