The levator scapulae inserts on to the vertebral margin of the scapula between the superior angle and the root of the spine.

Where does the levator scapulae originate?

The levator scapulae originates from the posterior tubercle of the transverse process of cervical vertebrae one to four. The muscle is inserted into medial border of the scapula extending from superior angle to junction of spine and medial border of scapula.

What is the function of the levator scapula?

The levator scapulae muscles are superficial extrinsic muscles of the back that primarily function to elevate the scapulae.

What is the origin and insertion of the trapezius muscle?

Trapezius Attachments

It originates on the occipital bone, the ligamentum nuchae, and the spinous processes of T01–T12. The trapezius inserts on the lateral third of the clavicle, as well as the acromion and scapular spine of the scapula.

What is the origin of the levator scapulae quizlet?

The origin of the levator scapulae muscle is the spinous processes of the upper four cervical vertebrae (C1-4). The medial border of the scapula above the scapular spine is the insertion point of the levator scapulae.

What is the origin and insertion of the supraspinatus muscle?

The supraspinatus muscle originates from the supraspinous fossa, which is a concave surface at the top of the scapula. From the supraspinous fossa of the scapula, the supraspinatus muscle then extends laterally (outward) and inserts onto the humerus, which is the long bone that makes up the upper arm.

What is the origin insertion and action of the serratus anterior?

The serratus anterior is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest and inserts along the entire anterior length of the medial border of the scapula. The serratus anterior acts to pull the scapula forward around the thorax.

What is the origin and insertion of the rhomboids?

Origin & Insertion

The rhomboid major is quadrangular muscle located inferior to the rhomboid minor. The origin of the rhomboid muscles is from the spinous processes of the T2-T5 vertebra and inserts on the medial border of the scapula, just inferior to the rhomboid minor.

What is levator scapulae syndrome?

Introduction. Levator Scapulae Syndrome is an historical name for “pain over the upper medial angle of the scapula” Levator scapulae pain is one of the most common general muscle complaints. Understanding the levator scapulae is helpful for both preventing and treating levator scapulae pain.

What is the origin and insertion of the pectoralis minor?

It originates from the margins of the third to fifth ribs adjacent to the costochondral junction. The fibers consequently pass upward and laterally to insert into the medial border and superior surface of the coracoid process of the scapula.

What nerve supplies the levator scapulae?

A 2016 cadaver study reported that the levator scapulae was innervated solely by the dorsal scapular nerve in 48% of cases and that the levator scapulae and rhomboids with both innervated by the same dorsal scapular nerve in 52% of samples.

Which is the insertion of the trapezius?

Insertion. The muscle inserts on the lateral third of clavicle, acromion, and spine of scapula.

What is the insertion of the latissimus dorsi?

Origin of the latissimus dorsi is from spinous processes of thoracic T7–T12, thoracolumbar fascia, iliac crest and inferior 3 or 4 ribs, inferior angle of scapula and insertion on floor of intertubercular groove of the humerus.

What is the insertion of the pectoralis major quizlet?

Origin: Juncition of rib 1 and its costal cartilage, insert inferior surface of middle third of clavicle, innervation: Nerve to subclavius (C5-C6), FX: Anchors and depresses clavicle.
