Overview Gluteal muscles form the fullness of the hip. They originate on the pelvis and insert on the femur. The gluteus maximus also attaches to the tibia via the iliotibial band. Primarily, these muscles extend and abduct the hip joint. In addition, the lateral glutes are vital in supporting the pelvis while the opposite leg […]

Overview Piriformis is the largest, muscle in the lateral hip rotator group. Also, it is the only lateral rotator that attaches to the sacrum. Origin Insertion Function Nerve Piriformis assists in tilting the pelvis. Also, the muscle stabilizes the pelvis when weight shifts to swing the opposite limb. Piriformis has a different origin than other
Here, you will find anatomy for the triceps coxae, which consists of the obturator internus, gemellus superior, and gemellus inferior. These three muscles were originally grouped as a single muscle. Like the triceps brachii, they have a common insertion and function. Later, they were separated because of different origins and innervation. According to one study,
Here, you will find the anatomy of the quadrants femoris muscles. Also, you will find functional considerations and all of the related posts in this blog. Overview Quadratus femoris is one of the deep lateral hip rotators. It is a flat, rectangular muscle posterior to the hip joint. Origin Insertion Function Nerve Quadratus femoris is
Overview The obturator externus is a flat, triangular muscle that extends from the lower pelvis to the superior femur. The muscle has a superior belly and the main belly. Its name comes from its attachment to the external surface of the obturator foramen. Its counterpart, obturator internus, originates from the internal surface. Origin Insertion Function
Overview The gluteus maximus is a large flat muscle on the posterior hip. It is the largest muscle in the human body. It is seen as one of the distinctive human features as it is larger and more developed than other mammals, including apes. Origin bony attachments of the posterior crest of the ilium, sacrum,
The anatomy of gluteus medius is similar to several other muscles like infraspinatus, and masseter. Likewise, it has three bellies and a tough fascial covering. The gluteus medius is a fan-shaped muscle on the lateral hip that overlays the gluteus minimus. The posterior portion lies under the gluteus maximus. Commonly, it has three sections that
Fascia Lata The fascia lata is the deep fascia that wraps the outer thigh. This thick fascial envelope attaches superiorly to the crest of the Ilium and inguinal ligament. The fascia continues onto the pubic rami, ischial tuberosity, sacrotuberous ligament, coccyx, and sacrum. Distally, it thickens as it attaches to the proximal tibia. It offers

Here, you will find an overview of the anatomy of the gluteus minimus muscle and links to related posts. It has two distinct heads. Origin Insertion Function It has a strong relationship with adductors in stabilizing the pelvis’s lateral motion, rotation, and elevation. Innervation Piriformis and gluteus maximus trap the os coxae between the femur
