What is the source of the male sex hormones?
- A. epididymis
- B. vas deferens
- C. seminiferous tubules
- D. interstitial cells
Correct Answer: D
Rationale: The correct answer is D: interstitial cells. Interstitial cells, also known as Leydig cells, are located in the testes and are responsible for producing male sex hormones, primarily testosterone. The other choices, A: epididymis, B: vas deferens, and C: seminiferous tubules, are not directly involved in the production of male sex hormones. The epididymis is a structure for sperm maturation, the vas deferens is a duct for transporting sperm, and the seminiferous tubules are responsible for sperm production through spermatogenesis. Therefore, interstitial cells are the source of male sex hormones, making choice D the correct answer.

The cortical area of the ovary contains:
- A. primordial follicles;
- B. mature follicles;
- C. secondary follicles;
- D. blood vessels;
Correct Answer: A
Rationale: Step 1: The cortical area of the ovary is the outer layer where follicles develop.
Step 2: Primordial follicles are the earliest stage of follicle development, found in the cortex.
Step 3: Mature follicles are developed follicles located deeper in the ovary, not in the cortex.
Step 4: Secondary follicles are also more developed than primordial follicles, located deeper.
Step 5: Blood vessels are important for supplying nutrients but are not specific to the cortical area.
Therefore, the correct answer is A as primordial follicles are located in the cortical area, while other choices are found in different regions of the ovary.
During a physical examination of the male reproductive system, how does the nurse assist the examiner to gather clues about the density of scrotal tissue?
- A. Through a digital rectal examination
- B. By externally inspecting the size of the scrotum
- C. Through transillumination
- D. Through a scrotal radiography
Correct Answer: C
Rationale: Transillumination helps assess the density and presence of fluid in the scrotum.
Lower jaw bone is called as
- A. Maxilla
- B. Mandible
- C. Temporal bone
- D. Menton
Correct Answer: B
Rationale: The lower jaw bone is known as the mandible. The mandible is the only movable bone in the skull, forming the lower jaw and holding the lower teeth in place. The maxilla (A) is the upper jaw bone. The temporal bone (C) is a bone that forms part of the skull, but it is not the lower jaw bone. Menton (D) is a landmark on the mandible, not the name of the bone itself. Therefore, the correct answer is B (Mandible) as it is specifically designated as the lower jaw bone.
The presence of more oxytocin oxygen to, and remove waste from, receptors in the uterus leads to weak, irregular contractions known as the embryonic blood by the ________ ________. week of pregnancy.
- A. dystocia
- B. first
- C. Braxton Hicks
- D. second
Correct Answer: C
Rationale: The correct answer is C: Braxton Hicks contractions. These contractions are weak, irregular contractions that occur in the uterus during pregnancy. They are often referred to as "practice contractions" as the body prepares for labor. The presence of more oxygen and removal of waste from the uterus can trigger Braxton Hicks contractions.
Choice A, dystocia, refers to difficult or prolonged labor, not weak contractions. Choice B, first week, is not relevant to the question as Braxton Hicks contractions typically occur later in pregnancy. Choice D, second week, is also not correct as Braxton Hicks contractions occur later in pregnancy, typically in the third trimester.
Which gland surrounds the upper portion of the urethra just below the junction with the urinary bladder?
- A. Ejaculatory
- B. Seminal vesicles
- C. Bulbourethral
- D. Prostate
Correct Answer: D
Rationale: The correct answer is D: Prostate. The prostate gland surrounds the upper portion of the urethra just below the junction with the urinary bladder. It secretes a fluid that makes up a significant portion of semen. The other choices are incorrect because:
A: Ejaculatory gland is not a correct anatomical structure.
B: Seminal vesicles are located behind the bladder and contribute to semen production.
C: Bulbourethral glands are located at the base of the penis and secrete a lubricating fluid during arousal.
