Overview Peroneus longus, also called fibularis longus, is a lateral low leg muscle. It wraps around the lateral foot attaches to the inferior surface. Origin head and proximal third of the lateral tibia Insertion base of the first metatarsal medial cunieform Function eversion of the foot Nerve superficial fibular nerve, sacral plexus, (L4-S3) Peroneus longus, …
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. The lateral glutes are key in supporting the pelvis while the ipsilateral leg lifts and …

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 medial margin of the greater sciatic notch anterior sacrum from the Level of S2-S4 superior portion of the sacrotuberous ligament Insertion superior greater trochanter Function lateral rotation of the femur …
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 lateral border of the ischial tuberosity …
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. It is usually …
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 …
Gluteus medius is a fan-shaped muscle on the lateral hip. It overlays the gluteus minimus. The posterior portion lies under the gluteus maximus. Commonly, it has three sections that converge into a single insertion tendon. Origin lateral exterior surface of the ilium between the anterior and posterior gluteal lines Insertion superior, anterior aspect of the …
Brief Overview The Tensor fascia lata is a small fusiform muscle that, with some variance, tapers at the ends. Origin – the anterior lip of the crest of the ilium Insertion – lateral, condyle of the tibia via the IT band Function – stabilizes the hip and knee, weak hip flexor and medial rotator Detailed …
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 …
