A relatively long and mind boggling quiz about the organs of the endocrine system.

1

The _______, or pituitary gland, is also known as the master gland.
- Adenohypophysis
- Neurohypophysis
- Infundibulum
- Hypophysis
2

The __ controls the activities of the adenohypophysis ( also known as the anterior pituitary).
- Hypothalamus
- Pituitary gland
- Pineal gland
- Infundibulum
3

The following is not a tropic hormone (hormone that has a stimulating effect on other endocrine glands)
- Thyroid stimulating hormone (TSH)
- Adrenocorticotropic (ACTH)
- Follicle stimulating hormone (FSH)
- Prolactin (PRL)
- Luteinizing hormone (LH)
4

The neurohypophysis, or posterior pituitary serves as a storage and release site for:
- lymphocytes
- gonadotrophs
- antidiuretic hormone (ADH) and oxytocin (OT)
- lutenizing hormone (LH) and FSH
5

Triggered by nervous stimulation, oxytocin :
- causes milk ejecting from lactating breast and stimulates contraction of uterine muscles
- prevents formation of large volume of urine thus conserving water
- dehydration that triggers release of ADH
- melatonin sectrion
6

The pineal gland:
- is not a tiny pine cone-shaped structure located on the dorsal aspect of the brain's diencephalon
- is not a member of both nervous system (receives visual stimuli) and endocrine system (which secretes hormones)
- is not essential for maintaining normal BP by aiding noradrenaline and adrenaline to cause vasoconstriction
- is not the primary melatonin secretor
7

The thyroid hormone does not secrete:
- tetraiodothyronine (T4)
- oxytocin
- triiodothyronine (T3)
- calcitonin
8

Calcitonin works to:
- decrease blood calcium levels, promote conservation of hard bone matrix
- work as an agnonist to parathyroid hormone
- regulate sodium homeostasis in the blood
- cause more bone to dissolve yielding calcium and phosphate
9

The following is not one of the 3 layers of secreting cells exist in the adrenal cortex:
- Mineralcorticoids
- Glucocorticoids
- Gonadocorticoids and androgens
- Adrenocorticoids
10

Aldosterone in mineralocorticoids do not:
- increase sodium reabsorption in kidneys
- increase water retention
- promote loss of hydrogen ions and phosphate
- cause a shift in CHO catabolism to lipid catabolism as an energy source
11

Glucocorticoids:
- cause a shift in CHO catabolism to lipid catabolism as an energy source
- are essential for maintaining normal BP by aiding noradrenaline and adrenaline to cause vasoconstriction
- act with adrenaline to aid recovery from inflammatory process
- secretion increases in response to stress
- All of the above
- None of the above
12

_ cells in pancreatic islets in the endocrine portion of the pancreas secrete glucagon, increase blood glucose levels and stimulate gluconeogenesis.
- A cells
- B cells
- D cells
- Pancreatic polypeptide cells (F or PP cells)
13

The ____ produces testosterone responsible for growth and maintenance of male se-xual characteristics and is regulated by gonadotropins
- Ovaries
- Testes
- Gonads
- FSH
14

The ovaries:
- produce estrogens and progesterone (maintains lining of uterus for egg implantation)
- are tissues that form the lining of pregnant uterus and connects circulatory system between mother and child
- secrete as temporary endocrine gland that secretes human chorionic gonadotropin (hCG), estrogens and progesterone
- regulate other endocrine cells of pancreatic islets
15

Thymosin and thymopoietin, which stimulate the development of T cells, are found in the:
- thyroid gland
- heart
- thymus
- mineralocorticoids
16

___ , secretin and cholecystokinin in the gastric and intestinal mucosa are required for digestion:
- gastrin
- ghrelin
- ANH
- ADH
17

__ stimulates the hypothalamus to boost appetite and slows metabolism and fat burning
- ANH
- Ghrelin
- Gastrin
- Secretin
18

ANH produced by the heart functions to:
- oppose increases in BP or blood volume
- secrete thymosin and thymopoietin hormones to stimulate development of T cells
- stimulate the hypothalamus to boost appetite
- slow metabolism and fat burning
