The Male Reproductive Tract

Did you try to identify the structures before starting to read this?

A. testis; B. head (B1), body (B2) and tail (B3) of the epididymis; C. proper ligament of the testis; The ligament of the tail of the epididymis attaches the tail of the epididymis to the scrotal wall; D. ductus deferens; E. pampiniform plexus of the testicular artery and vein; F. spermatic cord. The mesothelium that surrounds the testes and the epididymis is the visceral vaginal tunic. Continuous with the parietal paritoneum through the inguinal canal and into the scrotum is the parietal vaginal tunic (G). The testis and testicular vessels are suspended by the mesorchium (H), and the ductus deferens is suspended by the mesoductus deferens (I). Along the spermatic cord, the mesoductus deferens and the mesorchium come together and have a common trunk that is continuous with the parietal vaginal tunic - this is the mesofuniculus (J). The cremaster muscle (K), which is a strip off the internal abdominal oblique muscle, attaches to the outer surface of the parietal vaginal tunic. See if you can find these structures on the lab specimens.
