What structure is responsible for testicular descent during development? Tunica albuginea Inguinal canal Vaginal tunic Tunica dartos muscle Gubernaculum testis Please select an option Incorrect. The tunica albuginea is a connective tissue layer containing some smooth muscle fibres. Contraction and relaxation of these fibres results in a pumping action facilitating the flow of spermatozoa through the tubules of the testes. The translocation of the testis is the result of growth and contraction of the gubernaculum testis which is a ligamentous structure extending from the site of the future scrotum, through the inguinal ring to the caudal testis. The gubernaculum testis regresses and leaves behind remnants which can be found in the adult; the proper ligament of the testis and the ligament of the tail of the epididymis. WikiVet Article: testes. Incorrect. The inguinal canal is the structure through which the testes descend from the abdomen into the scrotum. The translocation of the testis is the result of growth and contraction of the gubernaculum testis which is a ligamentous structure extending from the site of the future scrotum, through the inguinal ring to the caudal testis. The gubernaculum testis regresses and leaves behind remnants which can be found in the adult; the proper ligament of the testis and the ligament of the tail of the epididymis.WikiVet Article: testes. Incorrect. The vaginal tunic is made up of parietal and visceral layers of peritoneum which are dragged into the scrotum during testicular descent. The translocation of the testis is the result of growth and contraction of the gubernaculum testis which is a ligamentous structure extending from the site of the future scrotum, through the inguinal ring to the caudal testis. The gubernaculum testis regresses and leaves behind remnants which can be found in the adult; the proper ligament of the testis and the ligament of the tail of the epididymis. WikiVet Article: testes. Incorrect. The tunica dartos muscle is responsible for holding the testes close to the body during cold temperatures and letting the testes lower in hot weather. The translocation of the testis is the result of growth and contraction of the gubernaculum testis which is a ligamentous structure extending from the site of the future scrotum, through the inguinal ring to the caudal testis. The gubernaculum testis regresses and leaves behind remnants which can be found in the adult; the proper ligament of the testis and the ligament of the tail of the epididymis. WikiVet Article: testes. Correct! The translocation of the testis is the result of growth and contraction of the gubernaculum testis which is a ligamentous structure extending from the site of the future scrotum, through the inguinal ring to the caudal testis.
