penis
scrotum
prostate
pair of spermatic cords
question 151
the urethral orifice is ______ to the vagina opening.
posterior
anterior
medial
lateral
question 152
mechanical support and protection for developing germ cells in the testis are provided by:
tunica albuginea.
sertoli cells.
interstitial cells.
rete testes.

Explanation:

Question 150

To solve this, we analyze each option:

• Penis: Supports and has a role in reproduction (erection for intercourse, etc.).
• Scrotum: Supports the testes.
• Prostate: Is a gland (part of the reproductive system's internal glands, not a supporting structure like the others which are more structural/supportive in holding organs).
• Pair of spermatic cords: Supports the testes.

So the prostate is not a supporting structure in the same way as the others.

In female anatomy, the urethral orifice (opening of the urethra) is located anterior (in front of) the vaginal opening. Posterior would be behind, medial is towards the midline, lateral is away from the midline. So the correct term is anterior.

• Tunica albuginea: A fibrous layer around the testis, more for overall structure of the testis.
• Sertoli cells: Provide mechanical support, nourishment, and protection to developing germ cells (spermatids, etc.) in the seminiferous tubules.
• Interstitial cells: Produce testosterone, not support germ cells.
• Rete testes: Involved in sperm transport, not support.

So Sertoli cells provide the needed support and protection.

Answer:

C. Prostate
