Question

Which of the following is incorrectly paired with its function?
a. Seminiferous tubules- add fluid to containing mucus fructose and prostaglandins to semen
b. Scrotum- encases testes and suspends them below the abdominal cavity
c. Epididymis- stores sperm
d. Prostate gland- adds alkaline secretion to semen

Answer 1

Hint: The points mentioned in the question all represent the male reproductive system. These organs are situated outside the body of the male and within the pelvis. There are most of the organs which are external genital organs and some are internal genital organs.

Complete answer:
> The seminiferous tubules are the structure where the processes such as germination, maturation, and transportations the sperm cells within the male testes occur. Seminiferous tubules are made up of the Sertoli cells surrounded by spermatogenic cells They are responsible for nourishment to the developing spermatozoa. So option A is the correct answer.

> The scrotum is a sac skin that remains hanging out from the body at the front. It remains outside of the body as it needs to maintain a slightly lower temperature than the rest of the body. It encases testes and suspends them below the abdominal cavity. So this option B is incorrect.

> The epididymis is a tightly coiled structure that stores sperm for maturation. So, option C is incorrect.

> The main function of the prostate gland is to provide alkaline secretion to semen. So, option D is incorrect.

Hence, the correct answer is option (A), Seminiferous tubules- add fluid to containing mucus fructose and prostaglandins to semen.

Note: Seminiferous tubules are present within the male testes. At seminiferous tubules, germination, maturation, and transportation of the sperm cells take place. They are made up of columnar Sertoli cells. The scrotum is a sac of skin that encases the testes and suspends them below the abdominal cavity. The scrotum is generally hanging out from the body at the front of the testis.
