What is the anatomy of testis; including the cord & the 2 muscles there.

Expert Solution

ANATOMY OF TESTIS AND SPERMATIC CORD

The most superficial layer of the testis is the tunica albuginea, which gives rise to septa that divide the tissue of the testis into lobules. The lobules of the testis contain one to four highly convoluted seminiferous tubules. Each convoluted seminiferous tubule becomes a straight seminiferous tubule before entering the mediastinum. Straight tubules interconnect to form a collecting chamber called rete testis.

The rete testis gives rise to 15-20 efferent ductules which penetrates the capsule of the testes and connect with the epididymis. The epididymis consists of a head where the efferent ductules merge and the body and tail extends along the posterior margin of the testes. The ductus deferens is a continuation of the epididymis and enters the spermatic cord.

The spermatic cord carries the ductus deferens, testicular artery, artery to ductus deferens, cremasteric artery, pampiniform plexus, genital branch of the genitofemoral nerve, lymphatics and the sympathetics.

The coverings of the testis from inside out includes the tunica vaginalis, internal spermatic fascia, cremasteric muscle, external spermatic fascia and the dartos muscle.
