Muscles: Gluteal Region
| Question | Answer |
|---|---|
| Gluteus Maximus | O: Posterolateral aspect of the ilium, posterior aspects of sacrum and coccyx, and sacrotuberous ligament I: Pass inferiorly and laterally to IT band and the gluteal tuberosity A: Femur-Ext. & ER and Knee-Ext I: Inf. Gluteal Nerve (L5-S2 PD) |
| Gluteus Medius | O: Upper lat. Aspect of the wing of ilium I: Converges with G.Min on Greater Trochanter A: Main abductors of femur. Prevent hip adduction in stance. I: Superior Gluteal Nerve (L4-S1 PD) |
| Gluteus Minimus | O: Same as G. Medius but inferior I: Converges with G. Min on Greater Trochanter A: Main abductors of femur. Prevent hip adduction in stance. I: Superior Gluteal Nerve (L4-S1 PD) |
| TFL | O:Anterior-most part of iliac crest I: Descends vertically and inserts into ant. portion of the IT band (1/3 of the way down) A: Contributes to thigh flexion and IR. Not primary mover I: Superior Gluteal Nerve (L4-S1 PD) |
| Piriformis | O: Deep or ventral aspect of the sacrum I: Fibers pass anterolaterally through the greater sciatic foramen (which muscle fills). Medial aspect of greater trochanter. A: ER femur I: (S1, S2 PD) |
| Superior Gemellus | O: Ischial spine I: join tendon of Obturator Internus into greater trochanter A: ER femur I: (L5-S2 AD) |
| Inferior Gemellus | O: Ischial tuberosity I: join tendon of Obturator Internus into greater trochanter A: ER femur I: (L4-S1 AD) |
| Obturator Internus | O: Deep aspect of the rim of obturator foramen I: Medial aspect of the greater trochanter Note: tendon glides around smooth bony ant. wall of lesser sciatic foramen to insertion A: ER femur I: (L5-S2 AD) |
| Quadratus Femoris | O: Lateral aspect of ischial body I: fibers pass laterallt. Central aspect of the posterior intertrochanteric region of the femur A: ER femur I: (L4-S1 AD) |
