The deferent duct joins with the ........ and forms.........:
- A. the seminal vesicle duct;
- B. the urethra;
- C. the ejaculatory duct;
- D. the epididymal duct;
Correct Answer: C
Rationale: The correct answer is C: the ejaculatory duct. The deferent duct, also known as the vas deferens, joins with the seminal vesicle duct to form the ejaculatory duct. This is where sperm from the testes and fluid from the seminal vesicles combine before entering the urethra during ejaculation. The other choices are incorrect because the seminal vesicle duct does not directly join with the deferent duct, the urethra is not formed by the deferent duct, and the epididymal duct is not involved in the formation of the ejaculatory duct.

At what point in life does a female begin her monthly ovarian cycle?
- A. At birth
- B. At puberty
- C. At middle age
- D. At menopause
Correct Answer: B
Rationale: The correct answer is B: At puberty. The monthly ovarian cycle, also known as the menstrual cycle, begins at puberty when a female's body matures and starts ovulating. This is typically around the age of 11-14. At birth (A), females already have all their eggs but do not start ovulating until puberty. Middle age (C) refers to the period around 40-65, which is not when the cycle begins. Menopause (D) is the cessation of the menstrual cycle, marking the end of reproductive years, typically around the age of 45-55.
The process of release of ovum from the ovary is termed as
- A. Dessication
- B. Ovulation
- C. Fenestration
- D. Maturation
Correct Answer: B
Rationale: The correct answer is B: Ovulation. Ovulation is the process of the release of the mature egg (ovum) from the ovary. During ovulation, the egg is released into the fallopian tube where it can potentially be fertilized by sperm. Dessication (A) refers to the process of drying out, Fenestration (C) is the creation of an opening or hole, and Maturation (D) is the process of becoming mature. Therefore, the correct term specifically related to the release of the egg from the ovary is ovulation.
Regarding respiratory system of fetus
- A. Respiratory bud starts to appear at the ventral wall of foregut at approximately week 10 of gestation
- B. There are 4 stages of development of respiratory system
- C. Development of respiratory tract is not complete until the last week of fetal development.
- D. Epithelial respiratory is derived from endodermal
Correct Answer: A
Rationale: The correct answer is A because the respiratory bud does indeed start to appear at the ventral wall of the foregut around week 10 of gestation. This marks the beginning of respiratory system development. Choice B is incorrect as there are actually 5 stages of respiratory system development. Choice C is also incorrect as the development of the respiratory tract is not fully complete until after birth, not just in the last week of fetal development. Choice D is incorrect because the epithelial respiratory lining is derived from endoderm, not endodermal.

_______ is a lytic enzyme released by the sperm.
- A. Hyaluronidase
- B. Trypsin
- C. Helicase
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Hyaluronidase. This enzyme is released by the sperm to help penetrate the outer layer of the egg during fertilization. Hyaluronidase specifically breaks down hyaluronic acid present in the cumulus cells surrounding the egg. Trypsin is a digestive enzyme found in the pancreas, not involved in sperm function. Helicase is an enzyme involved in DNA replication and repair, not released by sperm. "None of the above" is incorrect as hyaluronidase is indeed released by the sperm.
