Document Summary

Cell to cell communication molecules: *get stuff from online* Hormones secreted by endocrine glands or cells into the blood. Only target cells w/ receptors for endocrine system. Endocrine cells localized by specific tissues in endocrine glands: hypothalamic, thyroid, pancreas, ovaries, testes, what determines whether a cell in our body is a target for hormone insulin, presence of insulin receptor in the cell. Hormone fxn: cellular mechanism of action. Receptors localized on cell surface (plasma membrane receptors) cellular response. In adrenal glands/cortex, specialized cells produce androgens (female: adrenal gland-- adrenal cortex can produce hormones that are steroids.
