Q

capsule of the testis

A

3 layers

  • tunica vaginalis is simple squamous mesothelium
    formed of inner ( visceral ) and outer (parietal ) layer
  • tunica albuginea under tunica vaginalis is collagenous
    fibres , thick posterior to form mediastinum of testis
  • tunica vasculosa under tunica albuginea is CT, rich in
    blood capillaries

Q

function of sertoli

A

nutrition support phagocytic cell
form blood testis barrier secretes inhibitor hormones which inhibit FSH , so control spermatogenesis
secretes testicular fluid rich in androgen binding protein (ABP ) which promotes action of testestrone and FSH
