The perineal muscles are a group of muscles located in the pelvic floor, which support the pelvic organs, including the bladder, uterus, and rectum. These muscles play a crucial role in maintaining urinary and fecal continence, as well as contributing to sexual function. There are two main groups of perineal muscles: the superficial and deep perineal muscles. The superficial group includes the bulbospongiosus and ischiocavernosus muscles, while the deep group consists of the levator ani and coccygeus muscles. Strengthening these muscles can improve pelvic health and prevent issues such as incontinence.
