Question

Which of the following helps in the descent of the testes from the abdominal cavity?

• A. Scrotum
• B. Inguinal canals
• C. Gubernaculum
• D. Mesorchium

Answer 1

The correct option is B Inguinal canals

Testes are primary sex organs in human males associated with the production of sperms (male gametes) and male sex hormones (androgens).
In humans, the testes of are formed in the abdomen of the foetus during the 7${}^{\mathrm{th}}$-8${}^{\mathrm{th}}$ week of pregnancy. During the 7${}^{\mathrm{th}}$-8${}^{\mathrm{th}}$ months of pregnancy, the testes descends into the scrotum through the inguinal canals.
The scrotum is present outside the abdominal cavity. It maintains a temperature of 2-2.5℃ lower than the body temperature, required for the production and viability of sperm.
The testes remain connected to the wall of the scrotum by the gubernaculum.
The testes hang in the scrotum with the help of spermatic cords which is a tubular structure arising from the vas deferens and rich in blood vessels, lymph vessels, nerves and ducts.
Mesorchium is a fibrous sheath that attaches the vascular (blood vessels, lymph vessels) and avascular (nerves and cremaster muscles) structures of the spermatic cord.
