The diagram reflects the histological makeup of the prostate with compound tubuloalveolar acini feeding into a system of ductules and finally forming 30-50 excretory ducts that enter into the prostatic urethra. In this diagram the two ejaculatory ducts are shown posterior to the prostatic urethra, and represent the confluence of the ducts of the seminal vesicles and the vasa deferentia. At a slightly more inferior level of the axial cut, they will enter the prostatic urethra at the verumontanum CODE prostate normal tubulaoalveolar gland duct epithelium cuboidal columnar simple epithelium ductules ducts ejaculatory ducts histology Davidoff Art Image Courtesy Ashley Davidoff Copyright 2010
