The piriformis muscle
, also called the pyramidal pelvic muscle
, belongs to the thigh and pelvis
region. The piriformis muscle begins in the sacrum, passes through the buttocks
, and ends at the femur. The piriformis muscle is located in the pelvis
between the viscera and the upper leg
. The piriformis nerve and sacral and gluteal arteries
pass through the piriformis muscle. The piriformis allows for the separation and rotation of the thighs outwardly toward the sides.
