Anatomy, Male Genitalia

Model Of The Internal Anatomy Of An Adult Male Pelvis Median Section. The Pelvic Musculature And Vascular Network, As Well As The Spinal Column, Are Described In Image No. 1149205. The Ureter In Greenish Yellow Carries The Urine From The Kidney To The Bladder. The Urinary Bladder Wall Is Mainly Composed Of The Bladder Muscle In Orange Red, The Contraction Of Which Allows Urine Evacuation Through The Urethra. This Muscle Is Inwardly Covered By A Mucous Membrane In Orange With Many Folds And, Outwardly, By The Perimetrium In White. The Rectum Is Composed Of Two Segments: The Rectal Ampulla In Its Upper Part, Storing The Feces, And The Anal Canal, Ending In The Anus. The Rectal Ampulla Forms Curves, Giving Rise To Folds Of The Inner Rectal Mucosa The Rectal Valves. It Also Has Vertical Folds, The Anal Columns. The Rectal Wall Includes Three Tissue Layers: An Outer Muscularis In Orange Red, Constituted By Muscle Fibers Allowing Defecation, A Middle Submucosa And An Inner Mucosa In Orange. The Opening Of The Extremity Of The Anal Canal, The Anus, Is Controlled By An Internal Anal Sphincter, Composed Of Smooth Muscle In Orange, Reflex Opening For Defecation And An External Anal Sphincter Of Striated Muscle In Red, Voluntary Relaxation. Outside The Pelvic Cavity, The Testicles In Khaki, Located In The Scrotum, Produce Spermatozoa And Secrete Sex Hormones. The Scrotum Wall Is Inwardly Covered By The Colles' Fascia In White Including A Bundle Of Muscle Fibers, The Dartos, In Contact With The Abdominal Wall. Each Testicle Is Wrapped In The Tunica Vaginalis In White And In A Fibrous Capsule, The Tunica Albuginea In White, The Projections Of Which Form Walls Separating The Testicle Into Lobules. Spermatogenesis Takes Place In These Lobules, Then The Spermatozoa Are Propelled Towards The Duct Of The Epididymis. The Epididymis In Grey Is Mainly Made Up Of This Duct, A Long Curled U (Photo By BSIP/UIG Via Getty Images)
