The primary germ layer that gives rise
- A. areolar glands to the mucosae and associated glands
- B. lacrimal glands is the ________.
- C. sweat glands
- D. ectoderm
Correct Answer: D
Rationale: The correct answer is D: ectoderm. The primary germ layer that gives rise to structures like the lacrimal glands is the ectoderm, which is one of the three primary germ layers during embryonic development. The ectoderm gives rise to tissues such as the epidermis of the skin, nervous system, and various glands including lacrimal glands. Choice A, areolar glands to the mucosae and associated glands, is incorrect as they are derived from the mesoderm. Choice C, sweat glands, is also incorrect as they are derived from the ectoderm but are not the primary germ layer responsible for lacrimal glands. Choice B, lacrimal glands is the _______, is incorrect as it does not provide a complete statement and is not a primary germ layer.

The reproductive cycle of a human is usually regulated by
- A. gametes
- B. hormones
- C. natural selection
- D. immune responses
Correct Answer: B
Rationale: The correct answer is B: hormones. Hormones play a crucial role in regulating the human reproductive cycle by controlling the release of gametes and coordinating the processes of ovulation and menstruation. Hormones such as estrogen and progesterone interact with the reproductive organs to maintain the menstrual cycle and facilitate fertility. Natural selection (C) is the mechanism of evolution, not directly related to regulating the reproductive cycle. Immune responses (D) are involved in protecting the body from pathogens, not in regulating the reproductive cycle. Gametes (A) are the reproductive cells, but they are not responsible for regulating the reproductive cycle.
Circular movement around an axis is known as ___________________.
- A. Dorsiflexion
- B. Rotation
- C. Extension
- D. Pronation
Correct Answer: B
Rationale: The correct answer is B: Rotation. Circular movement around an axis is described as rotation. This movement involves turning or spinning around a fixed point. Dorsiflexion (A) is the movement of bringing the top of the foot towards the shin. Extension (C) refers to straightening or increasing the angle of a joint. Pronation (D) is the inward rotation of the forearm or foot. Rotation (B) specifically signifies movement around an axis, making it the most appropriate choice for circular movement.
The pituitary FSH controls:
- A. the maturation of the ovarian follicles;
- B. the estrogen secretion;
- C. ovulation;
- D. the progesterone secretion;
Correct Answer: A
Rationale: The pituitary FSH (Follicle Stimulating Hormone) controls the maturation of ovarian follicles by stimulating their growth and development. FSH plays a crucial role in the early stages of the menstrual cycle. Estrogen secretion is primarily regulated by the ovaries, not FSH. Ovulation is mainly triggered by the surge in LH (Luteinizing Hormone) levels, not FSH. Progesterone secretion is mainly controlled by the corpus luteum, which forms after ovulation, not directly by FSH. Therefore, the correct answer is A as FSH directly influences the growth and maturation of ovarian follicles.
Paraurethral (Skene’s) glands secrete
- A. Estrogen
- B. Mucus
- C. Testosterone
- D. Androgens
Correct Answer: B
Rationale: The paraurethral (Skene's) glands are responsible for secreting mucus to facilitate lubrication during sexual arousal. This mucus aids in lubricating the urethra and providing moisture for sexual intercourse. Estrogen (Choice A) is a hormone produced by the ovaries and not directly related to the function of Skene's glands. Testosterone (Choice C) and androgens (Choice D) are male sex hormones and are not involved in the secretion of mucus by Skene's glands. Therefore, the correct answer is B, mucus, as it aligns with the known function of the paraurethral glands.
