As revealed in Determine 27.two, the centrally Positioned prostate gland sits anterior to the rectum at the base of the bladder encompassing the prostatic urethra (the portion of the urethra that operates within the prostate). In regards to the dimension of the walnut, the prostate is shaped of the two muscular and glandular tissues.
