Anatomy, Male Genitalia

Model Of The Internal Anatomy Of An Adult Male Pelvis Median Section. The Withdrawal Of The Digestive Organs And The Internal Genitalia Make It Possible To View The Pelvic Wall. The Inner Surface Of The Anterior Pelvic Wall On The Left Of The Picture Is Covered With The Superficial Fascia Including Fat In Yellow. It Is Followed By The Rectus Abdominis Muscle In Red, Which Is Bordered By A Thick Aponeurosis Membrane White Line. The Pelvic Vascular Network Arteries In Red And Veins In Blue Includes: The Common Iliac Artery Derived From The Abdominal Aorta, Bringing The Oxygenated Blood To The Lower Part Of The Body And The Common Iliac Vein Draining The Deoxygenated Blood From The Pelvis And The Lower Limbs Towards The Inferior Vena Cava. At The Lumbar Intervertebral Disc Level, The Common Iliac Artery Divides Into Internal Posterior And External Anterior Iliac Arteries, Irrigating The Pelvic Structures And The Lower Limbs, Respectively. The Internal Iliac Artery Next Bifurcates Into An Anterior Giving The Obturator, Umbilical, Rectal And Internal Pudendal Arteries And A Posterior Divisions, Dividing In The Sacral Area. The Common Iliac Vein Transports The Blood Coming From The Internal And External Iliac Veins, Receiving A Network Of Veins Called Like The Arteries. The Inferior Epigastric Vessels, Branches Of The External Iliac Vessels, Irrigate The Abdominal Wall. The Obturator Nerve In Yellow Arises From The Lumbar Plexus And Goes Down Vertically Inside The Pelvis; It Goes Under The External Iliac Vessels And Innervates The Thigh Muscles. The Ureter In Greenish Yellow Carries The Urine From The Kidney To The Bladder. Upon The Lateral Pelvic Wall Lies The Iliacus Muscle In Red Followed By The Psoas Major Muscle, Flexor Of The Hip. Located On The Right Of The Common Iliac Vessels, The Obturator Internus Muscle Allows The Thigh Rotation Around The Pelvis; It Extends Tow (Photo By BSIP/UIG Via Getty Images)
