Figure 18.12 Which of the following statements about the male reproductive system is false?
a. The vas deferens carries sperm from the testes to the seminal vesicles.
b. The ejaculatory duct joins the urethra.
c. Both the prostate and the bulbourethral glands produce components of the semen.
d. The prostate gland is located in the testes.
Introduction:
The male reproductive system of the humans is a group of inter associated organs, which help in the formation of the gametes and their proper delivery out of the body. The male reproductive system also produces many hormones and other secretion important in reproduction and maintenance of the secondary sexual characteristics.
Answer to Problem 1ACQ
The correct answer is option (d).
Explanation of Solution
Explanation for the correct answer:
Option (d) prostate is located in testes. The prostate is a gland that is present between the bladder and the penis. It is a walnut-sized gland, which is situated just above the rectum. The urethra runs through the center of this gland. So, the prostate is located in testes is an incorrect answer. Hence, the correct answer is option (d).
Explanation for the incorrect answer:
Option (a) vas deferens carries the sperm to the seminal vesicles. The vas deferens carries the sperm from the testes to the seminal vesicles. From the seminal vesicles, the sperm is transferred to the ejaculatory duct. So, the vas deference carries the sperm to seminal vesicles is a correct statement. Hence, it is an incorrect answer.
Option (b) the ejaculatory duct joins the urethra. The pathway of the semen ejaculation and urine passage is the same. The ejaculatory duct joins the urethra, and share the same passage. Hence, it is an incorrect answer.
Option (c) both bulbourethral gland and prostate gland constitute the component of semen. The sperm is carried to the seminal vesicles and from there it is transferred to the ejaculatory duct. In the ejaculatory duct, the secretion of the prostate gland is added and down in the path, the secretion from the bulbourethral gland is added. So, the semen has the secretion of the bulbourethral gland and the prostate gland. Hence, it is an incorrect answer.
The prostate gland is not a part of testes. Hence, the option (d) is the correct answer.
