Anatomy-Abdomen

TESTIS

1. Possesses a thick covering - tunica albuginea.
2. The epididymis is attached to its posterolateral surface.
3. The tunica vaginalis covers the front and lateral surfaces of the testis. In hydroceles, this space becomes distended with fluid.
4. The testis, epidydimis, tunica vaginalis lie in the scrotum, covered by thin membranes which are a prolongation of the 3 coverings of the spermatic cord.
5. Supplied by the testicular artery (arises from the aorta at L2), drained by the pampiniform plexus (which drains into the renal veins). The left vein joins the left renal vein, right vein drains directly into IVC.
6. Varicoceles are more common on the left.
7. Lymphatics drain into the para-aortic nodes at L2.
