Process of giving birth is termed as
- A. Lactation
- B. Gestation
- C. Micturition
- D. parturition
Correct Answer: D
Rationale: The correct answer is D: parturition. Parturition refers to the process of giving birth. It involves the series of events that lead to the expulsion of the fetus from the mother's womb. Lactation (choice A) is the production of milk by the mammary glands after birth. Gestation (choice B) is the period of development of the fetus in the womb. Micturition (choice C) is the process of urination and is not related to childbirth. Therefore, the term that specifically describes the process of giving birth is parturition.

To avoid a perineal tear the obstetrician cuts the perineum posteriorly before delivery. This process is called
- A. Perineorrhaphy
- B. Episiotomy
- C. Cesarean section
- D. Tubal ligation
Correct Answer: B
Rationale: The correct answer is B: Episiotomy. An episiotomy is a surgical incision made in the perineum during childbirth to enlarge the vaginal opening and prevent severe perineal tears. This procedure is performed to facilitate the delivery of the baby and reduce the risk of complications for both the mother and the baby. Perineorrhaphy (A) is a surgical repair of a perineal tear or episiotomy after childbirth, not the procedure of making the incision. Cesarean section (C) is a surgical procedure to deliver a baby through an incision in the mother's abdomen and uterus, not related to perineal tears. Tubal ligation (D) is a permanent form of female sterilization by blocking or sealing the fallopian tubes to prevent pregnancy, not relevant to perineal tears during childbirth.
The accessory glands of the male reproductive system are:
- A. corpus spongiosum;
- B. corpus cavernosum;
- C. penis;
- D. seminal vesicles;
Correct Answer: D
Rationale: The correct answer is D: seminal vesicles. Seminal vesicles are accessory glands that produce a significant portion of the fluid that makes up semen. They contribute nutrients and substances that support sperm viability and motility. Choices A, B, and C are incorrect as they are structures of the penis involved in erection and urination, not accessory glands of the male reproductive system.
Milky-colored fluids secreted from the
- A. epididymis prostate ________.
- B. bulbo-urethral glands
- C. nourish sperm
- D. prostate
Correct Answer: B
Rationale: The correct answer is B: bulbo-urethral glands. These glands secrete a milky-colored fluid called pre-ejaculate or Cowper's fluid, which lubricates the urethra and neutralizes any acidic urine residue to protect sperm. The other choices are incorrect because the epididymis (A) stores and matures sperm, the prostate (D) secretes a milky fluid that nourishes and protects sperm, and option C is incomplete.
The endocrine role of the testicle:
- A. occurs at the level of the interstitial cells;
- B. consists in the secretion of androgenic hormones;
- C. consists in the secretion of testosterone;
- D. determines the maturation of the sex organs;
Correct Answer: C
Rationale: The correct answer is C because the endocrine role of the testicle primarily involves the secretion of testosterone. Testosterone is the main androgenic hormone produced by the testicles, which plays a crucial role in various physiological functions such as the development of male reproductive organs, sperm production, and secondary sexual characteristics.
Choice A is incorrect because while interstitial cells (Leydig cells) are involved in the production of testosterone, the endocrine role of the testicle is not limited to these cells alone.
Choice B is incorrect as it is too general. While androgenic hormones are indeed secreted by the testicles, testosterone specifically is the main androgenic hormone produced by them.
Choice D is incorrect as the maturation of sex organs is primarily regulated by the action of testosterone but is not the sole endocrine role of the testicle.
Female reproductive system arises from
- A. Paramesonephric (Mullerian) ducts
- B. Mesonephric (Wolffian) ducts
- C. aldosterone
- D. FSH
Correct Answer: A
Rationale: The female reproductive system arises from Paramesonephric (Mullerian) ducts. These ducts develop into the fallopian tubes, uterus, and upper part of the vagina. Initially present in both sexes, in females, they persist and differentiate into the female reproductive organs under the influence of estrogen. Mesonephric (Wolffian) ducts develop into male reproductive structures. Aldosterone is a hormone related to electrolyte balance and has no direct role in female reproductive system development. FSH (Follicle-Stimulating Hormone) is a pituitary hormone that stimulates ovarian follicle development but does not play a role in the initial development of the female reproductive system.
