Document Summary
Male reproductive system: lecture 2 (reading material: chapter 26: pages 707-709; chapter 27: pages 724-728: male duct system: how sperm gets out of the body, epididymis: to nourish and store/recycle sperm, which is constantly produced. Located in the scrotum, between the seminiferous tubules and vas deferens. Vas deferens + seminal vesicle duct = ejaculatory duct: ampulla: distal enlargement right before the prostate, the ejaculatory ducts penetrate the prostate and empty into the urethra (lined with simple columnar): empties into prostatic urethra. Lamina propria: lined with pseudostratified columnar epithelium with stereocilia, thick layer of smooth muscle: propels sperm during ejaculation. Inner longitudinal: middle circular, outer longitudinal, storage and transport of the sperm: Corporal sinusoids: deep and dorsal arteries of the penis, deep dorsal vein. Erect penis = erotogenic stimuli present and nanc neurons release nitric oxide. Nitric oxide activates guanylate cyclase converts gtp to cgmp to cause smooth muscles of corporal sinusoids to relax.
