FUNCTIONS OF EPIDIDYMIS

HISTOLOGICAL STRUCTURE OF EPIDIDYMIS Epididymis is a long, convoluted tubule that is surrounded by connective tissue & a thin smooth muscle layer. Both cross section & longitudinal section of epididymis shows mature sperm within the lumen of epididymis. The lining pseudostratified columnar epithelium consists of tall columnar principal cells with long nonmotile stereocilia & small basal cells.

IMPORTANCE OF TESTICULAR BLOOD SUPPLY

HOW TESTICULAR VEIN IS FORMED About 15 to 20 veins appear from the posterior border of testis & epididymis & unite to form a pampiniform plexus which produce the bulk of spermatic cord. At superficial inguinal ring the plexus unite to form 4 veins & at the deep ring they further join to form 2 veins. Finally a single vein is formed in the posterior abdominal wall. Right testicular vein drain directly into inferior vena cava at an acute angle, left testicular vein drain into left renal vein almost at a right angle.
