A mature ovarian follicle that is ready upper portion of the urethra just below to be ejected from an ovary is called a the junction with the urinary bladder. ________.

  • A. ejaculatory
  • B. primary oocyte
  • C. seminal
  • D. vesicular (Graafian) follicle
Correct Answer: D

Rationale: The correct answer is D: vesicular (Graafian) follicle. This structure is the final stage of maturation of an ovarian follicle before ovulation. It is characterized by a fluid-filled cavity and a bulging appearance on the surface of the ovary. It releases the mature egg during ovulation.

Rationale:
1. Ejaculatory (choice A) relates to the male reproductive system, not the female reproductive system.
2. Primary oocyte (choice B) refers to an immature egg cell, not a mature follicle.
3. Seminal (choice C) is related to semen production in males, not the female ovary.

In summary, the vesicular (Graafian) follicle (choice D) is the correct answer as it accurately describes the final stage of maturation of an ovarian follicle before ovulation.

The female Bartholin glands correspond to the male _____.

  • A. prostate
  • B. Cowper's
  • C. seminal vesicle
  • D. glans
Correct Answer: B

Rationale: The female Bartholin glands are homologous to the male Cowper's glands. Both glands secrete fluid to lubricate the reproductive tract during sexual arousal. The prostate gland (choice A) is not the correct answer as it is a different structure that produces seminal fluid. The seminal vesicles (choice C) secrete a significant portion of the seminal fluid but are not the male counterpart to the Bartholin glands. The glans (choice D) refers to the tip of the penis and is not the correct counterpart to the Bartholin glands. Therefore, the correct answer is B, Cowper's glands.

Middle layer of uterus is called:

  • A. Endometrium
  • B. Ectometrium
  • C. Myometrium
  • D. Perimetrium.
Correct Answer: C

Rationale: The correct answer is C: Myometrium. The myometrium is the middle layer of the uterus composed of smooth muscle tissue responsible for uterine contractions during childbirth. The endometrium (A) is the innermost layer responsible for menstruation and implantation. Ectometrium (B) is not a correct term. Perimetrium (D) is the outermost layer of the uterus. Therefore, C is the correct choice as it accurately represents the middle layer of the uterus.

The ovarian follicles are located in the following structures, EXCEPT:

  • A. the Fallopian tubes;
  • B. the uterus;
  • C. the medullar area of the ovary;
  • D. the cortical area of the ovary;
Correct Answer: B

Rationale: The correct answer is B, the uterus. Ovarian follicles are structures within the ovaries where oocytes (eggs) develop. The Fallopian tubes, medullar area, and cortical area of the ovary all contain ovarian follicles. The uterus, on the other hand, is not where ovarian follicles are located; it is the organ where a fertilized egg implants and a pregnancy develops. Therefore, the correct answer is B because the uterus is not a structure where ovarian follicles are present.

Lips of the vagina is termed as

  • A. Labial
  • B. Labia
  • C. Labrum
  • D. Labor
Correct Answer: B

Rationale: The correct answer is B: Labia. The term "labia" refers to the lips of the vagina. It is the plural form of "labium." "Labial" (A) refers to anything related to the lips, "Labrum" (C) refers to a rim or edge, and "Labor" (D) refers to the process of childbirth. Therefore, B is correct as it specifically refers to the structure being described.

Which of the following decreases the resistance in the arteries leading to the sinuses of the penis?

  • A. Stimulation of the sympathetic nerves innervating the arteries
  • B. Nitric oxide
  • C. Inhibition of activity of the parasympathetic nerves leading to the arteries
  • D. All of the above
Correct Answer: B

Rationale: The correct answer is B: Nitric oxide. Nitric oxide is a potent vasodilator that relaxes smooth muscle in the arterial walls, leading to decreased resistance in the arteries. This results in increased blood flow to the sinuses of the penis, contributing to erectile function.

A: Stimulation of the sympathetic nerves innervating the arteries would actually increase resistance by causing vasoconstriction.
C: Inhibition of activity of the parasympathetic nerves leading to the arteries would also increase resistance as parasympathetic stimulation typically leads to vasodilation.

Therefore, the correct answer is B as it directly causes vasodilation and decreases resistance in the arteries leading to the sinuses of the penis, which is essential for erectile function.
