Ans;D; All of the above
The structure marked as “E” in the picture below represents the ischial tuberosity.
Various adjoining muscles, bones and ligaments are attached with the ischial tuberosity:
- Gluteus Maximus: This is the main muscle which helps change a person’s posture during standing to sitting. It also holds the balance of the body. It is situated over the ischial tuberosity.
- Hamstrings: These are other important muscles which come from the ischial tuberosity. They are called the semi-membranosus, biceps femoris and semi-tendinosus. These three muscles are part of the hamstrings. Hamstring pain when sitting can occur. Hamstring tendonitis behind knee can occur. Hamstring pain under buttocks is common.
- Adductor Magnus: This major thigh muscle is also attached to the ischial tuberosity
- Sacrotuberous Ligament: The ischial tuberosity is connected to the sacrum by the sacrotuberous ligament. The ischial tuberosity attaches to two surfaces in this area:
- Exterior attachment to the gemellus superior
- Interior attachment of the coccygeus arises from the apex of the ischium and the levator ani muscle arises from the side of the pelvis / pelvic fascia
