The pelvic floor muscles are a group of muscles at the base of the pelvis that support your internal organs, help control bladder and bowel movements, contribute to core stability, and play a vital role in sexual health. Here is a list of the human pelvic floor and perineal muscles: Deep Pelvic Floor Muscles (Pelvic Diaphragm) Levator Ani Group Pubococcygeus Puborectalis Iliococcygeus Coccygeus (Ischiococcygeus) Superficial Perineal Muscles Superficial Transverse Perineal Muscle Bulbospongiosus Ischiocavernosus External Anal Sphincter Deep Transverse Perineal Muscle

Muscles located in the perineum (between the pubic symphysis and the coccyx), involved in urogenital and anal sphincter control are collectively referred to as the perineal muscles. Here is a list of the muscles in the human perineum: Superficial Perineal Pouch Bulbospongiosus Ischiocavernosus Superficial Transverse Perineal Deep Perineal Pouch Deep Transverse Perineal External Urethral Sphincter Sphincter Ani External anal sphincter Internal anal sphincter
