W7: Endocrine System Flashcards
(21 cards)
Define what a hormone is
potent chemical molecule secreted into blood from an endocrine cell that alters the metabolism of a tarter cell through binding to a specific receptor
A hormone is a chemical messenger produced by glands in the endocrine system that regulates various physiological processes in the body
Name the three chemical classes of hormones
1 - steroid
2 - monoamine (amino acide)
3 - peptide (chain of amino acids)
State the consequence of a target cell lacking the receptors to a certain hormone
target cell will not respond to hormone
Describe the action of tropic hormones
stimulates another type of endocrine gland to secrete a different hormone
Thyroid-Stimulating Hormone (TSH) stimulates the thyroid gland to secrete thyroid hormones (T3 and T4), which regulate metabolism.
Match the following endocrine organs to the hormone they produce
Adrenal Gland x 2
Adrenalin, aldosterone, cortisol
Match the following endocrine organs to the hormone they produce
Pineal gland
melatonin
Match the following endocrine organs to the hormone they produce
Parathyroid Gland x 4
Parathyroid hormone
Match the following endocrine organs to the hormone they produce
Anterior Pituitary
TSH (Thyroid-Stimulating Hormone)
ACTH (Adrenocorticotropic Hormone)
FSH (Follicle-Stimulating Hormone)
LH (Luteinizing Hormone)
Prolactin
GH (Growth Hormone)
Match the following endocrine organs to the hormone they produce
Thyroid Gland
thyroxine
Match the following endocrine organs to the hormone they produce
Hypothalamus
pituitary regulatory hormones, ADH, oxytocin
Match the following organs or endocrine tissues to the hormones they produce
Heart
Atrial na- tri-u-ver-tic peptide (ANP)
Match the following organs or endocrine tissues to the hormones they produce
Liver
angio- ten- sio- gen
Match the following organs or endocrine tissues to the hormones they produce
Thymus
thymopoietin
Match the following organs or endocrine tissues to the hormones they produce
Stomach
Gherlin
Match the following organs or endocrine tissues to the hormones they produce
Pancreas islets
insulin, glucagon
Match the following organs or endocrine tissues to the hormones they produce
Adipose
leptin
Match the following organs or endocrine tissues to the hormones they produce
Kidneys
calcitriol, erythropoietin
Match the following organs or endocrine tissues to the hormones they produce
Gonads
oestrogen, testosterone, inhibin
identify 4 hormones in the tables of question 8 and 9 that can influence blood glucose
1: Insulin
2: Glucagon
3: Thyroxine
4: Cortisol, adrenalin
Describe how insulin and glucagon work antagonistically in controlling blood glucose
Insulin = glucose into cells which decreases BGL
Glucagon = Glucose out of cells, which increases BGL
Nurses often administer prescribed insulin to diabetic patients
Explain why insulin (a peoptide hormone) is administer as a subcutaneous injection rather than an oral medication
avoids chemical digestion in atomic
1)pepsin (breaks peptide bonds)
2) Hydrochloric acid HCI denatures
