  1. Part II Splanchnology • Chapter 8 • The Reproductive System • The male reproductive organs • The female reproductive organs

  2. Section 1: The male reproductive organs • I . The general introduction: 2 parts • Internal Genital Organs: • gonad---testis, • ducts ---epididymis, • ductus deferens • ejaculatory ducts • urethra • accessory glands---seminal vesicle • prostate • bulbourethral glands • External genital organs: scrotum, • penis

  3. Ⅱ. The testis: • The features of testes--- • Paired oval-shaped organs • They are in the scrotum • (crypartt) • 2 extremities, • 2 surfaces, • 2 borders: • Posterior border— (mesorchial border) • connected with the epididymis • Anterior border---

  4. Ⅱ. The testis: • The structure of testes: • 12~13 efferent ductules of testis • tunica albuginea • mediastinum testis--- rete testis • septula testis • lobules of testis ---- • (100-200) • straight seminiferous tubules • interstitial tissue of testis (secretes sexual hormones) • convoluted seminiferous tubules ( produce sperms)

  5. Ⅲ. The Epididymis: • Position:in the scrotum, attached to the posterior border • of the testis • External feature: 3 parts--- • head, • body, • tail

  6. Ⅲ. The Epididymis: • Structure: • efferent ductules (head) • a coiled duct of epididymis • (body, tail) • ductus deferens

  7. Ⅳ. The ductus deferens: Four parts: • the testicular part, • the funicular (spermatic) part, • inguinal part, • pelvic part: longest part • -----ampulla ductus deferentis

  8. Spermatic cord: • ---soft round rope • ---upper extremity of the testis → deep ring of inguinal canal • ---main structure : • ductus deferense, • testicular artery • pampiniform plexus of vein • nervous plexus • lymphatic vessels • remnants of vaginal process • ---three tunics : • external spermatic fascia • cremaster • internal spermatic fascia

  9. external spermatic fascia cremaster internal spermatic fascia

  10. Ⅴ.The Ejaculatory duct: • Formation: It’s formed by the union of the end portion of the • ductus deferens and the seminal vesicle duct. • Position: It penetrated the base of the prostate, and opened into • the prostatic portion of urethra.

  11. Ⅵ. The male urethra: it’s15~20cm in length • Three parts • The prostatic portion • The membranous portion • The cavernous portion • Three constrictions • The internal orifice • The membranous portion • The external orifice • The three dilations • The prostatic portion • The bulbar portion of urethra • The navicular fossa • The two curvatures • The subpubic curvature • The prepubic curvature It can be chan

  12. Ⅶ. The prostate: • Location---in the lesser pelvic. Between the urinary bladder • and the urogenital diaphragm; in front of the rectum and • posterior to the pubic symphysis • Features--- Chestnut-shaped • apex ,base, • anterior surface, • posterior surface (a prostatic sulcus) • the urethra passed it • Structure: 5 lobes

  13. Ⅷ. The seminal vesicles: • oval sacculated organs • posterior to the fundus of urinary bladder • open to the ejaculatory duct Ⅸ. The bulbourethral gland • in the urogenitaldiaphragm • open to the bulbar portion of urethra

  14. Ⅹ.The Scrotum: • 2 layers---skin, • dartos (septum) • contents: testis, • epididymis, • spermatic cord • and its coverings

  15. Ⅺ. Penis: • External features: 3parts • head (glans) • body • root • Structures: • --- three cavernous bodys: • two cavernous bodys of penis • one cavernous body of urethra • --- albuginea of 3 cavernous bodies • --- deep fascia of penis • --- superficial fascia • --- skin • * Prepuce: skin is folded • * Frenulum Prepuce
