d
The region labelled by the blue arrow is divided into two parts by the piriformis muscle and the sciatic nerve passes through the superior portion of the division.
QuestionChoice
The structure labelled by the blue arrow is the greater sciatic foramen, an opening in the pelvic bone formed by the greater sciatic notch and closed off by the sacrospinous ligament. The sciatic nerve, the largest nerve in the body, passes through this foramen to enter the gluteal region. Specifically, it exits below the piriformis muscle through the infrapiriform foramen, which is a section of the greater sciatic foramen. This nerve supplies motor and sensory innervation to the posterior thigh, leg, and foot.
