Nokea
Anterior to the vagina and urethral openings is the
- A. Labia majora
- B. Labia minor
- C. Mons pubis
- D. Cervical sphincter
Correct Answer: A
Rationale: The correct answer is A: Labia majora. The labia majora are located anterior to the vagina and urethral openings, providing protection and support. The labia minora are internal to the labia majora. The mons pubis is the rounded mass of fatty tissue located over the pubic symphysis. Cervical sphincter is not a relevant anatomical structure in this context. Therefore, the labia majora is the correct choice based on its anatomical location and function.

Two inner folds, or ___________ minora, cover and protect the vaginal opening
- A. uterus
- B. fallopian tubes
- C. labia
- D. vagina
Correct Answer: C
Rationale: The correct answer is C: labia. The labia minora are two inner folds that cover and protect the vaginal opening. This is because the labia minora are part of the external female genitalia and specifically designed to provide protection to the vaginal opening.
A: Uterus - Incorrect. The uterus is a separate organ and is not involved in covering or protecting the vaginal opening.
B: Fallopian tubes - Incorrect. The fallopian tubes are part of the reproductive system but are not located near the vaginal opening or involved in its protection.
D: Vagina - Incorrect. While the vagina is connected to the vaginal opening, it is not the structure that directly covers and protects it.
The hormone testosterone is tubes called seminiferous tubules that produced by the ________ cells of the are found within each ________. testes.
- A. spermatic cord
- B. spermatogonia
- C. testis
- D. oogonia
Correct Answer: B
Rationale: The correct answer is B: spermatogonia. Spermatogonia are the cells within the seminiferous tubules of the testes that give rise to sperm cells. Testosterone is produced by Leydig cells, not spermatogonia. A is incorrect because the spermatic cord does not produce testosterone. C is incorrect as the testis is the overall organ where the seminiferous tubules are located. D is incorrect as oogonia are female germ cells found in the ovaries, not the testes.
Mammary papilla means the;
- A. Areola
- B. Lactiferous duct
- C. Sinuses
- D. Nipple
Correct Answer: D
Rationale: The correct answer is D: Nipple. The mammary papilla refers to the nipple, the protruding part of the breast where milk is released during breastfeeding. It is the anatomical structure that connects the lactiferous ducts to the outside of the body. The other choices are incorrect because:
A: Areola is the darker area surrounding the nipple.
B: Lactiferous duct is the tube that carries milk from the mammary glands to the nipple.
C: Sinuses are not directly related to the mammary papilla.
Shin bone is also known as
- A. Femur
- B. Tibia
- C. Fibula
- D. Patella
Correct Answer: B
Rationale: The correct answer is B: Tibia. The shin bone is commonly referred to as the tibia. This bone is located on the inner side of the leg and is the larger of the two lower leg bones. The femur (A) is the thigh bone, the fibula (C) is the smaller of the two lower leg bones, and the patella (D) is the kneecap. Therefore, the tibia is the correct answer as it specifically refers to the shin bone.
The result of oogenesis is _____.
- A. one secondary oocyte
- B. two secondary oocytes
- C. one ovum
- D. four ootids
Correct Answer: C
Rationale: The correct answer is C: one ovum. During oogenesis, a primary oocyte undergoes meiosis to produce one mature ovum and three polar bodies. The ovum contains the majority of the cytoplasm and organelles needed for fertilization. The other choices are incorrect because:
A: one secondary oocyte - After meiosis I, the primary oocyte develops into one secondary oocyte and one polar body.
B: two secondary oocytes - This is not a possible outcome of oogenesis as only one secondary oocyte is produced.
D: four ootids - Ootids are the immediate products of meiosis II in oogenesis and are not the final mature gametes like the ovum.
