Levator scapulae forms part of the latter group together with rhomboid major, rhomboid minor, serratus anterior, and trapezius. The trapezius evolved separately, but the other three muscles in this group evolved from the first eight or ten ribs and the transverse processes of the cervical vertebrae (homologous to the ribs).
The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side. In humans, it consists of the clavicle and scapula; in those species with three bones in the shoulder, it consists of the clavicle, scapula, and coracoid.
The location of the muscle in a standard human body. The location first specifies a group such as head, neck, torso, upper limbs, or lower limbs, then may have more specific information. However this additional information must be describing location not function. Origin The bone or other structure the muscle is attached to that remains ...
Apex: Union of the sternocleidomastoid and the trapezius muscles at the superior nuchal line of the occipital bone. Anteriorly: Posterior border of the sternocleidomastoideus. Posteriorly: Anterior border of the trapezius. Inferiorly: Middle one third of the clavicle. Roof: Investing layer of the deep cervical fascia. Floor: (From superior to ...
These muscles are responsible for several actions of the glenohumeral joint. The third group, which is mainly responsible for stabilization and rotation of the scapula, consists of the trapezius, serratus anterior, levator scapulae, and rhomboid muscles and attach to the medial, superior, and inferior borders of the scapula.
Anatomical terms of muscle [ edit on Wikidata ] The levatores costarum ( / ˌ l ɛ v ə ˈ t ɔːr iː z k ə ˈ s t ɛər ə m / ), twelve in number on either side, are small tendinous and fleshy bundles, which arise from the ends of the transverse processes of the seventh cervical and upper eleven thoracic vertebrae
The posterior axioappendicular muscles are described as two sub-groups: [1] [3] Superficial Posterior Axioappendicular muscles (or the extrinsic shoulder muscles) Trapezius; Latissimus dorsi; Deep Posterior Axioappendicular muscles (or the intrinsic shoulder muscles) Levator scapulae; Rhomboid minor; Rhomboid major
Posterior triangle is bordered by the posterior border of the sternocleidomastoid muscle, anterior border of the trapezius muscle and the superior edge of the middle third of the clavicle. This triangle contains the sternocleidomastoid, trapezius, splenius capitis, levator scapulae, omohyoid, anterior, middle and posterior scalene muscles. [1 ...
