During ovulation, the oocyte passes into the _____.
- A. uterine tube
- B. uterus
- C. pelvic cavity
- D. ovary
Correct Answer: A
Rationale: The correct answer is A: uterine tube. During ovulation, the mature oocyte is released from the ovary and travels through the uterine tube (fallopian tube) towards the uterus for potential fertilization. The uterine tube is the pathway for the oocyte to reach the uterus. Choices B, C, and D are incorrect because the oocyte does not directly pass into the uterus, pelvic cavity, or ovary during ovulation.

Benign tumors originating in the myometrium are
- A. Fibroids
- B. Rhabdomyoma
- C. Leiomyoma
- D. Both a & c
Correct Answer: D
Rationale: The correct answer is D (Both a & c) because benign tumors originating in the myometrium are typically either fibroids (choice A) or leiomyomas (choice C), which are essentially the same thing. Fibroids and leiomyomas are both non-cancerous growths arising from smooth muscle cells in the myometrium. Rhabdomyoma (choice B) is a benign tumor arising from striated muscle cells, not smooth muscle cells like fibroids and leiomyomas. So, choices A, B, and C are incorrect because only fibroids and leiomyomas specifically originate in the myometrium.
The point of junction of the muscle to the bone that moves is called the ___________________.
- A. Insertion
- B. Origin
- C. Sheath
- D. Fascia
Correct Answer: A
Rationale: The correct answer is A: Insertion. The point of junction of the muscle to the bone that moves is called the insertion because this is where the muscle attaches to the bone that it acts upon. The insertion is typically located distally in relation to the origin of the muscle. The origin, choice B, refers to the point of attachment of the muscle to the stationary bone. Choices C and D, Sheath and Fascia, are incorrect as they do not specifically refer to the point of junction of the muscle to the bone that moves.
The following statements about the prostate are true:
- A. it is an exocrine glandular organ;
- B. it is an unpaired organ;
- C. it secretes a fluid that is part of the semen;
- D. it is vascularized by a branch of the internal iliac artery;
Correct Answer: A
Rationale: Step-by-step rationale for the correct answer (A):
1. The prostate gland is an exocrine gland because it secretes its products through ducts onto an epithelial surface.
2. It is a paired organ, with two lobes located above the urethra and below the bladder.
3. The prostate secretes a fluid that contributes to the seminal fluid, not semen itself.
4. The prostate is vascularized by branches of the internal iliac artery, not the entire gland.
Therefore, the correct statement is that the prostate is an exocrine glandular organ (Choice A).
Which of these is not a function of estrogen?
- A. decreases adipose
- B. breast development
- C. increased skin blood vessels
- D. enlarges clitoris
Correct Answer: A
Rationale: Estrogen does not decrease adipose tissue; it actually promotes fat deposition in certain body areas. Breast development, increased skin blood vessels, and enlargement of the clitoris are all functions of estrogen. Adipose tissue regulation is influenced by other hormones like insulin and cortisol.
On which day of the female's uterine (menstrual) cycle does ovulation typically occur?
- A. Day 7
- B. Day 14
- C. Day 21
- D. Day 24
Correct Answer: B
Rationale: The correct answer is B: Day 14. Ovulation typically occurs around day 14 of a female's menstrual cycle. This is because ovulation is triggered by a surge in luteinizing hormone (LH) which usually happens midway through the cycle. Ovulation marks the release of an egg from the ovary, making conception possible. Days 7, 21, and 24 are not typically associated with ovulation as they are either too early or too late in the menstrual cycle for the surge in LH to occur. It is important to note that the timing of ovulation can vary among individuals and cycles, but day 14 is considered the average for a 28-day menstrual cycle.
