Biceps brachii, like the name implies, is a two headed muscle on the anterior brachium. It has a long, lateral head and a short, medial head. Origin long head – supraglenoid tubercle of the scapula short head – coracoid process Insertion tuberosity of the radius Function flexion of the elbow supination of the radio-ulnar joints …
The triceps brachii, as the name implies, is a 3 headed muscle on the posterior upper arm. It has a lateral, medial, and long head. The long head attaches to the scapula and ulna, trapping the humerus in-between them. Origin long head – infraglenoid tubercle of the scapula medial head – posterior humeral shaft, medial …
Overview of anatomy Iliocostalis is part of the erector spinae group, which also includes longissimus and spinalis. Iliocostalis, like the others, has 3 sections. All 9 sections of the erector spinae are gathered into a fascial compartment that extends along the spine. It is confusing to look at realistic illustrations of these muscles. Some Illustrations …

Occipitalis is part of a larger structure called the epicranius or occipitofrontalis muscle. The epicranius consists of the frontalis muscle and the occipitalis muscle which are joined by a fascial structure called the galea aponeurotica. The Occipitalis located on the posterolateral cranium. It has notable variations in area and thickness from person to person. Inferiorly, …
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 and including apes. This muscle originates along the bony attachments of the posterior crest …
Gluteus medius is a fan-shaped muscle on the lateral hip. It overlays the gluteus minimus and is overlapped, in the posterior portion by the gluteus maximus. Commonly, it has 3 sections that converge into a single insertion tendon. Origin – Lateral exterior surface of the ilium between the anterior and posterior gluteal lines Insertion – …
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 …
