- Note the unexpected arterial supply, venous drainage, lymph drainage and nerve supply of the testis.
- Discuss the embryological descent of the testes
- Describe the general structure of the testis.
- Consider the function of the Leydig cells (interstitial cells).
Germinal epithelium of the testicle
Leydig cells--secrete testosterone
Tunica albuginea--a dense capsule encasing each testis; which inhibits direct extension of tumor
Rete (ree' tee) testis--network of efferent ducts, analagous to the pelvis van die Nier
Epididymis--storage vessel for sperm--long coiled tube external to testis
Vas deferens (ductus deferens)--muscular extension of epididymis which carries sperm to urethra
