The pelvic floor is the inferior muscular layer of the true pelvic cavity. It separates the pelvic cavity superiorly from the perineum which lies inferior to the pelvic floor. It functions as a boundary of the pelvis and abdominal cavity while supporting the weight of the visceral organs.
Inside your body, your perineum contains structures that help you pee, poop and have intercourse.
the abdominal and pelvic cavity are often reffered to as the abdominopelvic cavity. there is no line betwene them and its depeest part is the pelvic floor musculature. the only seperation is between the greater and lesser pelvis as described below.
what marks the differentiation between the False (greater) and True (lesser) pelvic cavities?
the pelvic brim (which has many other names).
the perineum is divided into deep & superficial compartments anteriorly by the perineal membrane.
there is a resonable amount of this - its quite a broad question.
