levator ani .... is comprised of illicoccoygeus and the pubcoccoyeus. this makes the "floor or diaphragm" of the pelvi
Levator ani
Coccygeus
Diaphragm, Pelvic Floor, Internal Obliques and Transversus Abdominus
pelvic diaphragm
The Pelvis and Perineum are divided by 2 diaphragms 1. pelvic diaphragm made up of levator ani muscles which are attached at perineal body this arrangement is just like diaphragm muscle which has a central tendon like perineal body and inferiorly the pelvic diaphragm is covered by colles facia. 2.the other diaphragm is urogenital diaphragm, its upper layer is formed by parietal pelvic fascia and inferior layer is formed connective tissue perineal membrane, between these two layers is called deep perineal pouch which contain deep transverse perineii muscle which is a skeletal muscle and it acts as sphincter urethrae.

No, the abdominal and pelvic cavities are different. The abdominal cavity is superior to the pelvic cavity.
The floor of the pelvis is formed by the pelvic diaphragm.This diaphragm is formed by two layers of fascia with a middle layer of skeletal muscle.The muscles forming the middle layer are the levator ani and coccygeus muscles.The levator ani acts as a muscular sling for the rectum and marks the boundary between the rectum and the anal canal.Dr Rafi Hamidi
No. The thoracic and abdominal cavities are separated by the diaphragm.
The Pelvic Diaphragm
Major muscles included are the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm.
The pelvic floor is also called the pelvic diaphragm.
