Muscles of the pelvic floor (including puborectalis, pubococcygeus, iliococcygeus, coccygeus)

The **pelvic muscles**, or muscles of the pelvic floor, form a basin-shaped diaphragm that consists primarily of the skeletal muscles levator ani (puborectalis, pubococcygeus, iliococcygeus) and coccygeus[1][2][3][4]. They provide critical support for pelvic viscera, contribute to urinary and fecal continence, aid in sexual function and childbirth, and prevent pelvic organ prolapse. These muscles are innervated by the pudendal and sacral nerves and receive blood from branches of the internal iliac artery[2][3]. Clinical relevance includes their role in continence, support, and common conditions such as pelvic floor dysfunction and organ prolapse.
