Document Summary

Endocrine glands: lack ducts that are present in exocrine glands secrete their products, biologically active molecules called hormones, into the blood. Many chemicals, ex. norepinephrine, are secreted both as a neurotransmitter and a hormone. ** next page: list of endocrine glands, their major hormones, target organs, and primary effects ** If a o chain is larger than ~100 aas, ex. growth hormone has 191 aas. Hormones can be grouped under polar (water-soluble) and non-polar (insoluble in water, soluble in lipids) Polar hormones includes polypeptide and glycoproteins, and the catecholamine hormones secreted by the adrenal medulla, epinephrine, and norepinephrine. Non-polar hormones are called lipophilic hormones: unlike polar hormones, non-polar hormones can gain entry into their target cells through plasma membranes include steroid hormones and thyroid hormones o. Steroid hormones secreted by only 2 endocrine glands: adrenal cortex and the gonads adrenal cortex: corticosteroids (cortisol and aldosterone) and some sex steroids gonads: sex steroids.
