Answer 1

The coccyx, PSIS, and greater trochanter of the piriformis create a muscular sheet called the pelvic diaphragm.

Step-by-step explanation:

The coccyx, PSIS, and greater trochanter of the piriformis create a muscular sheet called the pelvic diaphragm. The coccyx, also known as the tailbone, is the final segment of the vertebral column and is located at the base of the spine. The PSIS (Posterior Superior Iliac Spine) is a bony prominence located on the posterior side of the ilium, which forms part of the hip bone. The greater trochanter of the piriformis is a bony projection on the upper part of the femur, which is a bone in the thigh.
