Protective supporting structures for the testes
- Tunica vaginalis (Parietal, Visceral)
- Tunica Albuginea
- Scrotum
- thermosensor
- radiator
- protective sac
- Scrotum cross section - skin, tunica dartos muscle, parietal tunica vaginalis, visceral tunica vaginalis, testicular parenchyma, mediastinum
Primary sex organ - testes
- Tunica albuginea
- Seminiferous tubules (sperm production)
- Interstitial tissue surrounds seminiferous tubule (testosterone)
- Rete Testis in Mediastinum
Secondary sex organs (leading to exterior)
- Efferent ducts (vas efferentia, ductuli efferentes)
- Epididymis - head, body and tail (caput, corpus, cauda)
- Vas deferens (ductus deferens)
- Ampulla of vas deferens
- Urethra (pelvic and penile)
Spermatic cord
- testicular artery, testicular vein, nerves,
lymphatics, vas deferens, external cremaster muscle
- Pampiniform plexus
- heat exchange
- testosterone exchange
- pulse pressure eliminator
- External cremaster muscle
Other structures in scrotum
- Tunica dartos muscle
- Gubernaculum (connective tissue)
Pelvic Genitalia, muscles and other structures
- Ampulla, urethra (secondary sex organs)
- Accessory sex glands - seminal vesicles, body of prostate, cowper's gland
- Colliculus seminalis
- Muscles - pelvic urethral muscle, bulbospongiosus muscle, ischiocavernosus muscle
- blood supply to penis via crus penis
The Penis
- Retractor penis muscle
- Bulbospongiosus muscle
- Tunica Albuginea
- Corpus Cavernosum
- Corpus Spongiosum
- Urethra
- End of Penis - prepuce, free part of penis, glans penis, urethral process, fossa glandis
