Anatomy of Perineum👧🧑✍️ || Boundaries, Facial Layers, Superficial and Deep Perineal Pouch & Contents

*** Anatomy of the Perineum || Boundaries, Fascial Layers, Superficial & Deep Perineal Pouches & Contents In this comprehensive video, explore the detailed anatomy of the perineum—a diamond-shaped anatomical region located between the thighs, inferior to the pelvic diaphragm. We cover everything from its boundaries to the layered fascial structures and the intricate spaces called the superficial and deep perineal pouches. *Boundaries of the Perineum:* Anteriorly: Lower border of pubic symphysis and arcuate ligament Posteriorly: Tip of the coccyx Anterolaterally: Ischiopubic rami and ischial tuberosities Posterolaterally: Sacrotuberous ligaments An imaginary transverse line (inter-ischial line) between the ischial tuberosities divides it into the anterior urogenital triangle and posterior anal triangle. *Fascial Layers:* The perineum has three key fascial layers: Superficial fascia (with fatty and membranous layers, the latter known as Colles’ fascia) Deep perineal fascia covering muscles of the superficial pouch Perineal membrane (inferior fascia of urogenital diaphragm) which separates the superficial and deep perineal pouches *Superficial Perineal Pouch:* Located between the perineal membrane and deep perineal fascia Boundaries: Inferiorly by the membranous layer of superficial fascia (Colles’ fascia) Superiorly by the perineal membrane Laterally by the ischiopubic rami Anteriorly open to the scrotum, penis, or labia and anterior abdominal wall Contents differ in males and females Males: root of penis (bulb and crura), bulbospongiosus, ischiocavernosus, superficial transverse perineal muscles, bulbo-urethral glands, perineal artery, and nerves Females: root of clitoris (bulbs and crura), bulbs of vestibule, similar muscles, greater vestibular glands, corresponding vessels and nerves *Deep Perineal Pouch:* Located superior to the perineal membrane within the urogenital triangle Boundaries: Inferiorly by the perineal membrane Superiorly by the superior fascia of the urogenital diaphragm Laterally by the ischiopubic rami Posteriorly by fused layers of the urogenital diaphragm and perineal body Contents: Males: membranous urethra, deep transverse perineal muscle, external urethral sphincter, bulbourethral glands, dorsal artery and nerve of penis Females: proximal urethra and vagina, equivalent muscles, arteries, and dorsal nerve of clitoris The deep pouch is a largely closed space, unlike the superficial pouch. This detailed anatomical overview is essential for understanding perineal function, surgical approaches, and clinical conditions involving this complex region. Watch the video to visualize the layers and pouches with 3D illustrations and learn the differences between male and female anatomy in this area. *** This description is expertly crafted for a YouTube audience interested in anatomy, medical students, and healthcare professionals, providing a clear and detailed breakdown suitable for engaging educational content.[1][2][3][4][5][6] [1](https://www.ncbi.nlm.nih.gov/books/NB...)
