Final Exam BMS 107 questions and
answers rated A+
What is a hormone? - correct answer ✔✔Chemical messenger released by a cell
that is transported by the blood stream to regulate the function of another cell
What is positive feedback? - correct answer ✔✔Less common. The effects of a
small disturbance on a system include an increase in the magnitude of the
protuberance.
Example of a positive feedback - correct answer ✔✔milk released from mammary
gland
What is negative feedback - correct answer ✔✔an endocrine gland will continue
to secrete hormones that affect target cells until messages come back from the
cells reporting that adequate levels of hormones are present. Most common
Example of negative feedback - correct answer ✔✔blood glucose levels
What is the hypothalamo-hypophyseal portal system? - correct answer ✔✔system
of blood vessels connecting the hypothalamus with the anterior pituitary gland.
Purpose of the hypothalamo-hypophyseal portal system - correct answer
✔✔quickly transport and exchange of hormones
, Which cells types are instrumental in producing thyroid hormones? - correct
answer ✔✔TSH, thyroid stimulating hormone
Which cell types secrete calcitonin? - correct answer ✔✔Parafollicular cells
3 zones of the adrenal cortex and their hormones they release - correct answer
✔✔1. zona glomerulosa: mineralocorticoids
2. zona fasciculata: glucocorticoids
3. zona reticularis: sex hormones
What hormones are secreted from the adrenal medulla? - correct answer
✔✔epinephrine
Where are the parathyroid glands located? - correct answer ✔✔Dorsal side of the
thyroid gland
How does the parathyroid hormone and calcitonin control blood calcium levels? -
correct answer ✔✔Stimulating osteoclasts, stimulating calcitriol, which promotes
calcium absorption in the intestines, causes calcium retention by the kidneys
Which cells within the pancreas secrete insulin? - correct answer ✔✔Beta cells
Which cells within the pancreas secrete glucagon? - correct answer ✔✔Alpha cells
How do the beta and alpha cells regulate blood glucose levels? - correct answer
✔✔alpha cells: cause an increase in blood glucose.
