Ischioanal Fossa 3D

  • Description                                                
    • * Is a fat-filled space located lateral to the anal canal and medial to the ischial tuberosity.
    • * Is bounded by the obturator internus muscle laterally and the pelvic diaphragm (levator ani muscle) medially.
    • * The base is formed by the skin and fascia of the perineum.
    • * The contents of the ischioanal fossa include the pudendal nerve, internal pudendal vessels, and fat.
    • * The pudendal nerve, which provides sensory and motor innervation to the perineum, branches into the inferior rectal nerve and perineal nerve within the ischioanal fossa.
    • * The internal pudendal vessels, which are a branch of the internal iliac artery, provide blood supply to the structures within the ischioanal fossa.
