10 Cards in this Set
- Front
- Back
|
-A pea-sized gland
-Connects with the hypothalamus -2 regions: anterior and posterior |
Pituitary gland
|
|
|
*Larger of the two regions
*Produces: -GH (growth hormone) or somatotropin -TSH (Thyroid-stimulating hormone or thyrotropin -Corticotropin -FSH (Follicle-stimulating hormone) -LH (Luteinizing hormone) -Prolactin |
Anterior pituitary gland
|
|
|
-makes up about 25% of the gland
-Serves as storage area for ADH (antidiuretic hormone/ vasopressin) and oxytocin which are produced by the hypothalamus |
Posterior pituitary gland
|
|
|
-Has 2 lobes
*Produces: T4 (Thyroxine), T3 (Triiodothyronine) and Calcitonin (maintains blood calcium level by inhibiting the release of calcium from the bone) -Alters secretion according to the calcium concentration in surrounding fluid -Body's major metabolic hormone -Regulates metabolism by speeding cellular respiration |
Thyroid gland
|
|
|
*Produces: PTH (parathyroid hormone), which helps regulate blood calcium balance
-Smallest endocrine glands -Embedded on posterior surface of the thyroid -Work together as a single gland |
Parathyroid gland
|
|
|
-Consists of 2 almond-shaped glands lying on top of a kidney
-Each function as separate gland -2 Types: Adrenal cortex & Adrenal medulla |
Adrenal glands
|
|
|
-Type of Adrenal gland
*Produces: Mineralcorticorticoids (primary aldosterone), Glucocorticoids (cortisol, cortisone & corticosterone) -small amounts of Androgens & Estrogens -small amounts of sex hormones |
Adrenal cortex
|
|
|
-Type of Adrenal Gland
-Functions as part of sympathetic nervous system *Produces: 2 catecholamines (Epinephrine & Norepinephrine) |
Adrenal medulla
|
|
|
-Performs both endocrine & exocrine function
*Endocrine func: -Regulated by islet of Langerhans -Alpha cells produce Glycogen to Glucose -Beta cells produce Insulin (lowers the blood glucose level by stimulating conversion of glucose to glycogen) -Delta cells produce Somatostatin (inhibits the rlease of GH, corticotropin & certain other hormone) *Exocrine Func: -Regulated by Acinar cells -Involves secretion of digestive enzymes (flow through the pancreatic duct to the duodenum) |
Pancreas
|
|
|
-Lies at the back of the 3rd ventricle of the brain
-Produces the hormone Melatonin |
Pineal gland
|
