Gland • An organ that produces a secretion called hormones
PITUITARY GLAND • Tiny structure size of grape • Located at base of brain • Connected to hypothalamus • Divided into anterior and posterior lobes
THYROID GLAND • Butterfly-shapedmass of tissue • located in the anterior neck on either side of the larynx, over trachea
PARATHYROID GLANDS • Four glands, each the size of a grain of rice • Attached to posterior thyroid
THYMUS • Endocrine gland and lymphatic organ • Located posterior to thesternum, above and in front of heart • Begins to disappear at puberty
ADRENAL GLANDS • Divided into the cortex and medulla • Located directly above the kidneys
