The process by which a secondary oocyte is ejected from the ovary is called ________.
- A. emission
- B. menses
- C. fertilization
- D. ovulation
Correct Answer: D
Rationale: The correct answer is D: ovulation. This process involves the release of a mature egg (secondary oocyte) from the ovarian follicle. During ovulation, the egg is released into the fallopian tube, where it can potentially be fertilized by sperm.
A: emission - Incorrect. This term typically refers to the discharge of semen from the male reproductive system.
B: menses - Incorrect. Menses refers to the shedding of the uterine lining during menstruation, not the release of an egg from the ovary.
C: fertilization - Incorrect. Fertilization is the process of the sperm uniting with the egg, which occurs in the fallopian tube after ovulation.

Human chorionic gonadotropin (hCG) produces fluid that activates sperm.
- A. prostatic urethra
- B. ovary.
- C. prostate
- D. corpus luteum.
Correct Answer: D
Rationale: The correct answer is D: corpus luteum. Human chorionic gonadotropin (hCG) is produced by the developing placenta during pregnancy. This hormone helps maintain the corpus luteum, which in turn produces progesterone to support the pregnancy. The fluid produced by the corpus luteum helps activate sperm for fertilization. Choices A, B, and C are incorrect as they are not directly involved in the production of hCG or the activation of sperm.
Which hormone is secreted by the corpus luteum after ovulation?
- A. Progesterone
- B. Relaxin
- C. LH
- D. FSH
Correct Answer: A
Rationale: The correct answer is A: Progesterone. After ovulation, the corpus luteum forms from the ruptured follicle and secretes progesterone to prepare the uterus for implantation. Progesterone helps maintain the endometrial lining for potential pregnancy. Choice B, Relaxin, is secreted by the corpus luteum, but its main function is to soften the cervix and pubic symphysis. Choices C and D, LH and FSH respectively, are pituitary hormones involved in the menstrual cycle regulation, not directly secreted by the corpus luteum.
Which hormone stimulates the secondary female sex organs?
- A. FSH
- B. LH
- C. GnRH
- D. estrogen
Correct Answer: D
Rationale: The correct answer is D: estrogen. Estrogen is the hormone that stimulates the growth and development of secondary female sex organs like the breasts, uterus, and fallopian tubes. It plays a crucial role in regulating the menstrual cycle and preparing the body for pregnancy. FSH and LH are hormones released by the pituitary gland that primarily regulate the ovarian cycle, while GnRH is a hormone released by the hypothalamus to stimulate the pituitary gland to release FSH and LH. Estrogen, being a primary female sex hormone, directly influences the development and function of secondary sex organs in females.
Mucous membrane partially or completely covering the vaginal orifice is called as:
- A. Clitoris
- B. Labia
- C. Hymen
- D. Vulva
Correct Answer: C
Rationale: The correct answer is C: Hymen. The hymen is a mucous membrane that partially or completely covers the vaginal orifice. It is a thin tissue located at the opening of the vagina. The hymen can vary in appearance and may partially cover the vaginal opening, making it an essential anatomical structure to consider. The other choices are incorrect because:
A: Clitoris - The clitoris is a highly sensitive sexual organ located above the vaginal opening, not covering it.
B: Labia - The labia are the folds of skin surrounding the vaginal opening, not covering it entirely.
D: Vulva - The vulva refers to the external female genitalia, including the labia, clitoris, and vaginal opening, but it does not specifically refer to the mucous membrane covering the vaginal orifice.
What type of glands are the glands of Moll?
- A. Endocrine gland
- B. Apocrine sweat gland
- C. Oil gland
- D. Sebaceous glands
Correct Answer: B
Rationale: The glands of Moll are a type of apocrine sweat glands located in the eyelids. They secrete a clear fluid that helps lubricate the eyes. The correct answer is B because apocrine glands are associated with hair follicles and produce a thicker secretion compared to eccrine sweat glands. Endocrine glands (A) secrete hormones into the bloodstream, oil glands (C) are associated with hair follicles and produce sebum, and sebaceous glands (D) are also oil-producing glands but are different from the glands of Moll.
