Structurally, it is composed of three cylindrical erectile tissues surrounded by connective tissue and skin 🌟. These include two corpora cavernosa (dorsally placed) and one corpus spongiosum (ventrally placed), which encloses the spongy (penile) urethra and ends distally in the glans penis. The erectile tissues are encased in a tough fibrous sheath called the tunica albuginea 🧬, which plays a crucial role in erection and rigidity. The root of the penis anchors it to the pubic arch and consists of the bulb (middle) and crura (right and left), which are extensions of the corpus spongiosum and corpora cavernosa respectively. The body (shaft) extends outward and ends in the glans, which is covered by the prepuce (foreskin) unless circumcised. • Blood supply is mainly via the internal pudendal artery, giving rise to the deep artery of the penis (to corpora cavernosa), bulbourethral artery (to corpus spongiosum), and dorsal artery (to skin and glans). • Venous drainage is via deep and superficial dorsal veins. • Nerve supply is through pudendal nerve (somatic), pelvic splanchnic nerves (S2–S4) for parasympathetic (erection), and hypogastric plexus for sympathetic (ejaculation). • Lymphatic drainage goes to superficial and deep inguinal lymph nodes 📍. Clinically, knowledge of penile anatomy is vital in conditions like erectile dysfunction, Peyronie’s disease, urethral injury, and penile carcinoma. Also, the mechanism of erection involves parasympathetic vasodilation, while ejaculation is a sympathetic reflex, making autonomic understanding essential in sexual health medicine 💡💯. #PenisAnatomy #MaleReproductiveSystem #ErectionMechanism #NEETPG2025 #FMGE2025 #USMLEPrep #UrologyBasics #PudendalNerve #MBBSAnatomy #HumanSexualHealth #MedicalYouTube #ConceptualMedicine #DrGBhanuPrakash #TunicaAlbuginea #PeyroniesDisease
