- follicle-stimulating hormone
- type I diabetes
- a hormone produced by the thyroid glands to regulate metabolism by controlling the rate of oxidation in cells
- b (FSH) Released from the anterior pituitary gland to target the ovaries & testes. In females it stimulates the development of follicles in the ovaries and in males it promotes the development of sperm cells (and stimulates the interstitial cells of the testes to produce testosterone).
- c produced by seminiferous tubules and acts on the hypothalamus to slow production of the gonadotropin-releasing hormones that control the release of FSH. (negative feedback system)
- d Butterfly shape, located above the trachea. Produces thyroxine (non-steroid hormone), which increases metabolic rate & oxygen consumption, especially in the heart, skeletal muscle, liver, & kidney.
- e starts in childhood where the pancreas is unable to produce insulin. Treatment; injection of insulin.

non-steroid hormones → made of either protein, peptides or amino acids. Not fat soluble (do not enter cell to exert their effect) Bind to the surface of target cells to trigger a rxn. within the cell.
mineralocorticoids → hormones of the adrenal cortex important for regulation of salt-water balance
adrenal medulla → outer region of the adrenal gland that produces glucocorticoids & mineralocorticoids, & sm. amt. of sex hormones.
antidiurectic hormone → (ADH) Released from the posterior pituitary gland to target the kidneys. It increases water reabsorption by kidneys.
endocrine system → release their secretions through ducts or tubes onto a body surface or into a cavity. ex. sweat, salivary or tear glands
