Document Summary

Endocrine: the chemicals are secreted into the blood and carried by blood and tissue fluids to the cells they act upon = can act at great distances. Paracrine: chemical signals that diffuse into the area and interact with receptors on nearby cells (cytokines, neurotransmitters) Autocrine: the cell signals itself through a chemical that it synthesizes and then responds to. Autocrine signaling can occur solely within the cytoplasm of the cell or by a secreted chemical interacting with receptors on the surface of the same cell. The endocrine system: refers to collection of glands of an organism that secrete hormones directly into circulatory system to be carried towards distant target organs. Hormone: is any member of a class of signaling molecules that are transported by the circulatory system to target distant organs to regulate physiology and behavior.
