What is a hormone and how does it act? Hormones are chemical messengers that are responsible for regulation. They are secreted into body fluids, mainly blood. It has specific actions on target tissues, which are any tissue that has specific receptors for that particular hormone. What is a paracrine gland? a secretion that enters interstitial fluid but affects only neighboring cells What is an autocrine gland? A secretion that only affects the secreting cell. What is an en...

Resting Membrane Potential & Action PotentialAction Potential - correct answer Abrupt, pulsatile changes in membrane potential. Property of excitable cells that consists of rapid depolarization followed by repolarization. AP's have same size & shape; are propagating; and are "all or nothing". Resting Membrane Potential - correct answer Undisturbed period of action potential when nerve is NOT transmitting impulses. Cell membrane is said to be polarized-inside of cell more negatively cha...
