1) Which of the following is not a parathyroid gland mechanism to maintain adequate levels of blood calcium?

• activation of osteoclasts
• inhibition of calcitonin synthesis
• increase in intestinal absorption of calcium ions
• increase calcium ion reabsorption by the kidneys
• inhibition of calcitonin synthesis

2) A man has been told that he is not synthesizing enough follicle-stimulating hormone (FSH), and for this reason he may be unable to father a child. Choose the correct statement to explain this problem.

• The man must be producing progesterone, which inhibits the synthesis of FSH.
• A hormone made in the adenohypophysis cannot influence fertility.
• FSH stimulates sperm production in the testes.
• FSH stimulates estrogen secretion by ovarian cells; therefore it is not

synthesized by males.

• FSH stimulates sperm production in the testes.

3) Which of the following is not a possible cause of conduction deafness?

• middle ear infection
• impacted cerumen
• cochlear nerve degeneration
• otosclero
• cochlear nerve degeneration

4) Which of the following is true about gustatory receptors?

• In order for a chemical to be sensed, it must be hydrophobic.
• Complete adaptation occurs in about one to five minutes.
• The receptors generate an action potential in response to chemical stimuli. 1 / 3

• All gustatory receptors have the same threshold for activation.
• The receptors generate an action potential in response to chemical stimuli.

5) Ordinarily, it is not possible to transplant tissues from one person to another, yet corneas can be transplanted without tissue rejection. This is because the cornea
