Male reproductive system ii penis & accessory glands. Describe anatomical features of penis: blood & nervous supply. Describe structures & nerves associated with male sexual response (erection & ejaculation) Contents of spermatic cord include: nerves to cremaster muscle (recall: fibers of internal oblique muscle, testicular artery, vas deferens, autonomic nerve fibers, pampiniform venous plexus. Formed by union of ducts of the seminal vesicles and the ductus deferens. At this point, both urine and semen are carried and ends as it joins with the urethra. Prostatic urethra: runs within prostate gland from internal urethral sphincter of bladder to urogenital diaphragm, receives openings of ejaculatory ducts, receives secretions from prostate gland. Membranous urethra: runs through urogenital diaphragm, runs from apex of prostate to the base of the penis (bulb, surrounded by: Perineal membrane: bulbourethral glands are present on each side (denoted by: *)
