Description

The diagram reflects the basic histological makeup of the prostate in axial projection. It is composed of 30% glandular tissue (white) and 70% stromal tissue (pink). The glandular tissue is made up of branching tubuloalveolar glands and the stroma consists of smooth muscle, collagen, elastic tissue and fibrous tissue. The compound tubuloalveolar acini feed into a system of ductules and finally form 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
