A small solid structure located posterior to the epididymal head is called which of the following?

• A. Appendix Testis
• B. Epididymis Tail
• C. Spermatic Cord
• D. Vas Deferens

Answer: (A)

The structure described is the appendix testis. It’s a tiny, solid outgrowth attached to the upper pole of the testis, located just behind the head of the epididymis. It’s a vestigial remnant of the Müllerian duct, which explains why it appears as a small, discrete nodule in that exact area. The other options don’t fit the description as well: the epididymis tail is a longer, curved part of the epididymis at the posterior aspect of the testis; the spermatic cord and the vas deferens are tubular, cord-like structures that run toward the inguinal canal, not small solid nodules behind the epididymal head.
