Proximal part of vas deferens forms highly convoluted:
Correct answer: B. Epididymal tubules
- A. Sperm duct
- B. Epididymal tubules
- C. Ejaculatory duct
- D. Urethra
Explanation
The proximal part of the vas deferens, also known as the epididymis, forms highly convoluted structures called epididymal tubules. These tubules are responsible for storing and maturing sperm cells.The epididymis is a long, coiled tube that is located behind the testis. It is divided into three parts: the head, the body, and the tail. The head of the epididymis is where the sperm cells are stored after they are produced in the testis. The body of the epididymis is where the sperm cells mature. The tail of the epididymis is where the sperm cells are stored before they are ejaculated. So B is the correct option.
