Pelvic diaphragm consists of all except
**Core Concept**
The pelvic diaphragm is a muscular and fibrous structure that separates the pelvic cavity from the perineal region. It plays a crucial role in maintaining continence and supporting pelvic organs. The pelvic diaphragm consists of two main components: the levator ani muscle and the coccygeus muscle.
**Why the Correct Answer is Right**
The correct answer will be the option that does not belong to the pelvic diaphragm. The levator ani muscle is a broad, flat muscle that forms the major part of the pelvic diaphragm, while the coccygeus muscle is a small, triangular muscle that inserts on the ischial spine and the sacrum. The pelvic diaphragm also includes the fascial layers that cover the muscles.
