The muscles of the back can be divided into three groups – superficial, intermediate and intrinsic. Superficial is associated with movements of the shoulder while intermediate is associated with movements of the thoracic cage. The deep muscle is associated with movements of the vertebral column. The deep muscles develop embryologically in the back, and are thus described as intrinsic muscles. The superficial and intermediate muscles do not develop in the back, and are classified as extrinsic muscles. Take a look at the following muscle back diagrams that we posted below to see more details of the muscle anatomy diagram.
The superficial back muscles are situated underneath the skin and superficial fascia. They originate from the vertebral column and attach to the bones of the shoulder: the clavicle, scapula and humerus. All these muscles are therefore associated with movements of the upper limb. The muscles in this group are the trapezius, latissimus dorsi, levator scapulae and the rhomboids. The trapezius and the latissimus dorsi lie the most superficially, with the trapezius covering the rhomboids and levator scapulae.
