Appendix of the epididymis
The right testis, exposed by laying open the tunica vaginalis. (Appendix of epididymis labeled at center right.)
Latin	appendix epididymidis
Gray's	subject #258 1242
Precursor	Wolffian duct

On the head of the epididymis is a small stalked appendage (sometimes duplicated). It is named the appendix of the epididymis (or pedunculated hydatid), and is usually regarded as a detached efferent duct.

This structure is derived from the Wolffian duct as opposed to the appendix testis which is derived from the mullerian duct remnant.
