@anatomyweasel: Meet the gemellus inferior—one of your deep hip stabilizers that almost nobody talks about. It originates from the ischial tuberosity and blends with obturator internus to insert on the medial greater trochanter, helping externally rotate and stabilize your hip. Every time you control knee alignment in a squat, hold turnout, or cut sideways in sport, this tiny muscle is quietly doing its job. #gemellusinferior #hipanatomy #deephiprotators #kinesiology #anatomystudy #ptstudent #dpt #medstudent Image: Gluteal Muscles that Move the Femur (b) by OpenStax College, via Wikimedia Commons — licensed under CC BY 3.0.
