Question

Describe the passage of the ductus deferens from the scrotal sac to seminal vesicles.

A) Inguinal canal, pelvic cavity, ampulla of ductus deferens
B) Pelvic cavity, inguinal canal, ejaculatory duct
C) Pelvic cavity, spermatic cord, prostatic urethra
D) Ejaculatory duct, inguinal canal, pelvic cavity

Answer 1

The ductus deferens travels from the epididymis through the inguinal canal into the pelvic cavity, widens at the ampulla, merges with seminal vesicle secretions in the ejaculatory duct, and proceeds to the prostate gland.

Step-by-step explanation:

The passage of the ductus deferens from the scrotal sac to the seminal vesicles begins with the ductus deferens extending from the epididymis into the abdominal cavity through the inguinal canal. It proceeds posteriorly into the pelvic cavity, advancing toward the posterior of the bladder where it broadens into the ampulla. At this point, the fluid containing sperm combines with secretions from the seminal vesicles in the ejaculatory duct. Finally, the ejaculatory ducts move the fluid into the prostate gland for further processing.
