Trunk and Spine Muscles
Origin – Iliac crest. Inguinal ligament. Thoracolumbar fascia. Insertion – Lower 3-4 ribs. Linea alba. Actions – Contraction of one side alone laterally bends the trunk to that side and rotates the trunk to the other side. Compresses the abdomen and supports the
Shoulder Muscles
Origin – Posterior crest of the ilium (via the Thoracolumbar fascia). Posterior sacrum. Spinous processes of T7-L5. Insertion – Intertubercular groove (between the greater and lesser tuberosities) of the humerus. Actions – Shoulder extension. Internal rotation

Anatomy, Fascia Layers
Aponeurosis can thin into a tendon and become a point of origin or insertion for other muscles. Some examples of aponeurotic fascia include the fascia of limbs, thoracolumbar fascia, and rectus sheath. It is the thicker of the 2 subtypes that are normally easily

Major Muscles CYQ Level 3
· Latissimus dorsi Origin Via thoracolumbar fascia (TLF) from spinous processes of T6– T12, lumbar and sacral vertebrae and iliac crest. Also lower 3–4 ribs and bottom (inferior) edge of scapula Insertion Top of the humerus (anterior) Joint crossed Shoulder (glenohumeral) joint Joint action Origin fixed: adducts and extends arm.
Latissimus Dorsi: Anatomy and Function
When it comes to the lats, the origin is complicated, but the insertion is simple. At the top, the lats muscle originates from the bottom six thoracic vertebrae and the last three or four ribs. Part of the origin also includes the thoracolumbar fascia at the level of the lumbar and sacral vertebrae, as well as the back one-third of the outside part of the top of your hip bone.
Thoracolumbar Junction Pain Syndrome: a Cause of …
· While dysfunction of the thoracolumbar junction (TLJ) is a common occurrence in adult patients, 1,2 there seems to be a paucity of evidence for how to conservatively manage the condition. 3 While the TLJ has traditionally been thought to span T12-L1, various studies suggest that it may extend from T9-L2. 4-6 Robert Maigne first proposed the existence of Thoracolumbar Junction (TLT) Pain

Multifidus
Multifidus has a good lever arm for spinal extension due to its origin and insertion points. The muscle is a true lumbar extensor. In addition to extending the lumbar spine the muscle also acts as a stabilizer. As the muscle is encased in the thoracolumbar fascia
