BIOL 2402 Exam 1 (Endocrine System)
Which control system typically has slower, longer-lasting effects? - CORRECT
ANSWER-endocrine system
What general effects can hormones have on the characteristics of blood? - CORRECT
ANSWER-Maintaining homeostasis of blood composition and volume
hypothalamus is a link b/t - CORRECT ANSWER-nervous system and endocrine
system
pineal gland - CORRECT ANSWER-smallest gland
produces melatonin
endocrine glands - CORRECT ANSWER-pineal gland
pituitary gland
thyroid gland
parathyroid glands
adrenal glands
thyroid gland - CORRECT ANSWER-biggest gland
Organs Containing Endocrine Cells - CORRECT ANSWER-hypothalamus
skin
thymus
heart
liver
kidneys
stomach - small intestines
pancreas
, testis
ovaries
hormonal stimulation - CORRECT ANSWER-release of a hormone in response to
another hormone
ex:
1. anterior pituitary releases thyroid-stimulating hormone (TSH)
2. TSH stimulates thyroid gland to release thyroid hormone (TH)
humoral stimulation - CORRECT ANSWER-release of a hormone in response to
changes in level of nutrient or ion in the blood
ex:
1. blood glucose levels increase
2. increased blood glucose stimulates pancreas to release insulin
nervous system stimulation - CORRECT ANSWER-release of a hormone in response to
stimulation by the nervous system
ex:
1. sympathetic division is activated
2. sympathetic preganglonic axons stimulate adrenal medulla to release epinephrine
and norepinephrine
Is the entire pancreas an endocrine organ? - CORRECT ANSWER-no, both exocrine
and endocrine
Parathyroid hormone is secreted when? - CORRECT ANSWER-during humoral
stimulation when blood calcium levels are low
Categories of Circulating Hormones - CORRECT ANSWER-1. lipid soluble
2. water soluble
lipid soluble hormones - CORRECT ANSWER-1. steroids
Steroids - CORRECT ANSWER-synthesized from cholesterol
lipid-soluble
e.g., estrogen, cortisol, Calcitriol a sterol, progesterone, testosterone, aldosterone
water soluble hormones - CORRECT ANSWER-1. biogenic amines
2. proteins
Biogenic amines - CORRECT ANSWER-derived from amino acid that is modified
Which control system typically has slower, longer-lasting effects? - CORRECT
