The testicular lobules:
- A. are delineated by connective septa separated from the tunica albuginea;
- B. are separated by interstitial tissue;
- C. are made up of 2-3 convoluted seminiferous tubules;
- D. spermatogenesis occurs at their levels;
Correct Answer: C
Rationale: The correct answer is C because testicular lobules are indeed made up of 2-3 convoluted seminiferous tubules where spermatogenesis occurs. This process of sperm production takes place within the seminiferous tubules, making option C the most accurate description of the testicular lobules.
A is incorrect because the testicular lobules are not delineated by connective septa separated from the tunica albuginea. B is also incorrect as interstitial tissue is found between the lobules, not separating each individual lobule. D is incorrect as spermatogenesis specifically occurs within the seminiferous tubules, not at the level of the testicular lobules.

What area experiences the greatest changes in a menstrual cycle?
- A. vagina
- B. perimetrium
- C. cervix
- D. endometrium
Correct Answer: D
Rationale: The correct answer is D: endometrium. The endometrium undergoes the most significant changes during the menstrual cycle. It thickens and sheds in response to hormonal changes for potential implantation of a fertilized egg. The vagina (A), perimetrium (B), and cervix (C) do not experience the same level of cyclic changes as the endometrium. The vagina is primarily a passageway, the perimetrium is the outer layer of the uterus, and the cervix mainly functions as an opening to the uterus. Therefore, the endometrium is the area that experiences the greatest changes in a menstrual cycle due to its role in preparing for possible pregnancy and shedding if implantation does not occur.
Elbow, knee are _____ type of joints
- A. Ball-an
- B. socket
- C. Hinge
- D. Pivot
Correct Answer: C
Rationale: The correct answer is C: Hinge. Elbow and knee joints are classified as hinge joints because they primarily allow movement in one plane, similar to a door hinge. These joints enable flexion and extension movements, which are characteristic of hinge joints. The other choices (A: Ball-and-socket, B: Socket, D: Pivot) do not accurately describe the structure and function of the elbow and knee joints. Ball-and-socket joints allow for a wider range of motion in multiple directions, sockets are components of ball-and-socket joints, and pivot joints allow rotational movement around a central axis, none of which align with the movement pattern of the elbow and knee joints. Therefore, the correct classification for elbow and knee joints is hinge joints due to their specific range of motion.
The ovarian phase between the end of menstruation and beginning of ovulation is the
- A. Menstrual phase
- B. Preovulatory phase
- C. Proliferative phase
- D. Follicular phase
Correct Answer: C
Rationale: The correct answer is C: Proliferative phase. During this phase, the endometrium thickens in preparation for a potential implantation of a fertilized egg. This phase occurs after the menstrual phase and before ovulation, marking the time when the ovarian follicles are developing under the influence of FSH. The other choices are incorrect because the menstrual phase (A) refers to the shedding of the endometrium, the preovulatory phase (B) occurs just before ovulation, and the follicular phase (D) includes both the menstrual and preovulatory phases.
The corpus luteum secretes whereas oogenesis will produce ___
- A. FSH. ova/ ovum.
- B. LH.
- C. 2; 2
- D. prolactin.
Correct Answer: A
Rationale: The correct answer is A because the corpus luteum secretes progesterone, not FSH. Oogenesis produces ova/ovum, not FSH, LH, or prolactin. FSH and LH are hormones produced by the pituitary gland to regulate the menstrual cycle, not by the corpus luteum or involved in ova production. Prolactin is a hormone involved in milk production, not in oogenesis or corpus luteum function. Therefore, A is correct as it correctly identifies the function of the corpus luteum and the product of oogenesis.
