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 …
Anatomy for Massage and Bodywork is a collection of posts with illustrations that focus on relationships that interest the massage and bodywork practitioner. Understanding the relationship between muscles and their local joints is critical in effective Integrative Bodywork. Each muscle has illustrations that highlight the bones of attachments, and the bones trapped between the attachments. …
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. It originates along the bony attachments of the posterior crest of …
Gluteus medius is a fan shaped muscles on the lateral hip. It overlays the gluteus minimus and is overlapped, in the posterior portion by the gluteus maximus. It originates from the exterior surface of the ilium between the posterior gluteal line (by the crest) and anterior gluteal lines. The anterior two thirds is covered by …
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 The TFL tenses the fascia lata, stabilizing the hip joint by keeping the head of the …
The fascia lata is the deep fascia that wraps the outer thigh. It attaches superiorly to the crest of the Ilium and inguinal ligament continues onto the pubic rami, ischial tuberosity, sacrotuberous ligament, coccyx and sacrum. Distally it thickens as it attaches to the proximal tibia. It offers elastic stability, much like a compression stocking …

Sternocleidomastoid Anatomy. The sternocleidomastoid is a two-headed muscle that extends obliquely along the lateral neck. Origin: The sternal head attaches to the superior aspect of the manubrium. The clavicular head attaches to the medial third of the clavicle. Insertion: Both heads merge and attach to the mastoid process of the temporal bone and lateral third …
Gluteus minimus is a fan-shaped muscle deep in the lateral hip. It has two distinct heads. A thick head originates more anteriorly on the ilium and inserts closer to the joint capsule on the greater trochanter. It is stronger and better positioned to internally rotate the hip joint. A thin head originates more posteriorly and …
The major osseous structures of the pelvis are wrapped in a complex fascial structure that, like the osseous structures change and evolve as we age. In the first two decades, we have more boney pieces held together by cartilaginous plates that fuse as decades pass. Eventually, in our 4th or 5th decade, all of the …
