Question

Which of the following structures is not the content of a spermatic cord?
A) Vas- deferens
B) Testicular vessels
C) Testicular nerve
D) Deep artery of corpus cavernosa

Answer 1

In males, a cord like structure spermatic cord is present. This structure is formed by vas deferens and the surrounding tissue that runs from deep inguinal ring down to each of the testicles. The structure which is not the content of spermatic cord is the terminal branches of internal pudendal that arises from a vessel, while it is located between two fascia of urogenital diaphragm which is present at the deep perineal pouch.

Complete answer:
The structure's spermatic cord is formed by vas deferens or ductus deferens and the surrounding tissue that runs from deep inguinal ring down to each of the testicles. The tunica vaginalis which is the serosal covering of the spermatic cord is an extension of peritoneum that passes through transversalis fascia. Each testicle develops in the upper lumbar and lower thoracic region and then migrates into the scrotum during its descent it carries along with vas deferens, its nerves, vessels etc. Corpus cavernosum is the structure that is not the content of the spermatic cord. The term, artery to the corpus cavernosum which supplies blood to the penis, is used to describe the deep artery of penis. It pierces inferior fascia, and, obliquely entering the crus penis, and then runs forward in the center of the corpus cavernosum penis, where its branches are distributed.
The vas deferens, also known as the ductus deferens, is a tiny muscular tube structure in the male reproductive system which carries sperm from the epididymis to the ejaculatory duct.
The testicular artery is also known as the internal spermatic artery. It is a branch of abdominal aorta. It arises from the abdomen and reaches the scrotum by traversing the spermatic cord.
Testicular nerves arise mainly through three routes: nerves deriving from renal and mesenteric plexuses accompanied testicular artery, entering into the testicular hilum through superior ligament of testis.

Therefore, the answer is option D.

Note:
The spermatic cord is highly sensitive to torsion, in which the testicles rotate within the sac and block their own blood supply. Testicular torsion may cause irreversible damage to the testicles within hours.
