3All of the following are true statements except:
- Athere are at least 16 different prostaglandins
- Bthe first prostaglandin was identified in semen
- Caspirin produces some of its effects by increasing PGE synthesis

4Endocrine glands may be made up of
- Aglandular epithelium
- Bneurosecretory tissue
- Cducts to collect interstitial fluid
- Dboth glandular epithelium and neurosecretory tissue
5The many hormones secreted by endocrine tissues are structurally classified as
- Asteroid or nonsteroid hormones
- Banabolic or catabolic hormones
- Csex or nonsex hormones
- Dtropic or hypotropic hormones
6Which of the following is a function of glucagon?
- APromotes the entry of glucose into tissue cells

- Cthyroxine
- DT4 and thyroxine
8The production of thyroid hormone is stimulated by another hormone from the:
- Aanterior pituitary
- Bposterior pituitary
- Cthyroid gland.
- Dparathyroid gland
9The common molecule from which all steroid hormones are derived is
- Aphospholipids
- Bcholesterol
- Clecithin
- Dtriglycerols
10The first step in the renin-angiotensin mechanism is:
- Aangiotensin II circulates to the adrenal cortex, stimulating the secretion of aldosterone
- Brenin causes angiotensinogen to be converted to angiotensin I
- Cthe juxtaglomerular apparatus secretes renin into the blood in response to a fall in the blood pressure within the kidney
- Daldosterone causes increased reabsorption of sodium, which causes increased water retention

- Acyclic AMP
- BmRNA
- CATP
- DGTP
15Which of the following hormones is not secreted by the adrenal medulla:
- Aepinephrine
- Bnorepinephrine
- Cadrenaline
- Dall are secreted by adrenal medulla
16[blank_start]Tropic[blank_end] [blank_start]hormones[blank_end] target other endocrine glands and stimulate their growth and secretion
