Question #32
What is the predominant source of progesterone after ovulation?
- A . the oocyte
- B . the ovary
- C . the corpus callosum
- D . the corpus luteum
Correct Answer: D
D
Explanation:
Recall that the luteal phase of the menstrual cycle occurs after ovulation which occurs after the follicular phase. Progesterone saturation is highest during the luteal phase, and the corpus luteum is most responsible for this increased amount. The oocyte is an egg, which isn’t responsible for progesterone. The ovary is a source of progesterone, but not the primary source. And the corpus callosum is the point of juncture between the hemispheres of the brain.

Question #33
Which of the following is necessary for the penetration of an egg?
- A . the flagellum
- B . mitochondria
- C . acrosome
- D . centriole
Correct Answer: C
C
Explanation:
In order to penetrate an egg, a spermatozoon must bind with the exterior of the egg. This binding takes place by way of the acrosome reaction, in which the sperm penetrates the jelly coat of the egg to breach and fuse with the egg plasma membrane before releasing its constituents into the eggs cytoplasm.

Question #34
Which is the most inferior structure?
- A . stomach
- B . sigmoid colon
- C . pancreas
- D . small intestine
Correct Answer: B
B
Explanation:
Inferior refers to the area nearest the feet. Its opposite is superior, which refers to the area nearest the top of the head. In this case, the stomach is superior to both the pancreas and the small intestine which are both superior to the sigmoid colon. The sigmoid colon is nearest the feet of the options.

Question #35
Which hormone is released after a meal high in carbohydrates?
- A . insulin
- B . glucagon
- C . EPO
- D . ghrelin
Correct Answer: A
A
Explanation:
When the blood stream is over saturated with glucose (as a result of a meal high in carbohydrates), the pancreas releases insulin in order to regulate the glucose levels in the blood.

Question #36
Which of the following does NOT happen during inflammation?
- A . release of histamine
- B . an increase of local temperature
- C . migration of leukocytes
- D . constriction of blood vessels
Correct Answer: D
D
Explanation:
Inflammation causes dilation, not constriction of blood vessels. This dilation of blood vessels is designed to increase permeability across the blood vessels and facilitate mobility of white blood cells and other phages.

Question #37
Which of the following is NOT a result of sympathetic stimulation?
- A . increase in blood pressure
- B . increase of blood flow to intestines
- C . increase in blood flow to the brain
- D . dilation of pupils
Correct Answer: B
B
Explanation:
Sympathetic stimulation, associated with the fight-or-flight response, results in an increased blood pressure to help the body deal with a stressful situation. The body diverts blood away from digestion and the digestive system in favor of the skin, the muscles, and the brain.

A virus contains all of the following except?
- A . mitochondria
- B . RNA
- C . amino acids
- D . DNA
Correct Answer: A

- A . pons
- B . cerebrum
- C . cerebellum
- D . medulla oblongata
Correct Answer: B

- A . glycolysis
- B . TCA cycle
- C . ETC
- D . photosynthesis
Correct Answer: C
