Document Summary

Endocrinology - refers to how cells signal to each other/communicate. Crin - to secrete or let go. Autocrine signaling - a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell. Paracrine signaling (local signaling) - cell secretes a messenger that binds to receptors on a nearby or local cell. Endocrine signaling (long distance or hormonal signaling) - cell secretes a messenger that binds to receptors on a cell of a long distance, carried through the bloodstream. Hormone - induces a change in the cell; substance in the blood. Exocrine - released from a gland through a duct, not directly to the bloodstream. Sex hormones - testosterone, estrogen; influence your behavior, feelings, development, etc. Rhythms respond to what the body has learned is coming next.
