Study Notes

Muscles that Depress the Scapula and Clavicle

Lower Serratus anterior, Pectoralis minor, Lower pectoralis major, Subclavius, Lower latissimus dorsi, and Lower trapezius are the primary muscles involved in depressing the scapula and clavicle.

Lower Serratus Anterior

Originates from ribs 6-8 on the anterolateral side.
Inserts at the inferior angle of the scapula.
Innervated by the long thoracic nerve.

Pectoralis Minor

Originates from ribs 3-5 on the anterior side.
Inserts on the coracoid process of the scapula.
Innervated by the medial pectoral nerve.

Lower Pectoralis Major

Originates from the lower half of the sternum and costal cartilages of ribs 4-6.
Inserts at the lateral lip of the intertubercular groove.
Innervated by the medial pectoral nerve.

Subclavius

Originates from the costal cartilage of the first rib.
Inserts on the underside of the middle portion of the clavicle.
Innervated by the nerve to subclavius.

Lower Latissimus Dorsi

Originates from the spinous processes of vertebrae L1-L5, sacrum, and iliac crest.
Inserts at the intertubercular groove.
Innervated by the thoracodorsal nerve.

Lower Trapezius

Originates from the spinous processes of vertebrae T7-T12.
Inserts at the medial one-third of the scapula.
Innervated by the cranial nerve XI, the spinal accessory nerve.
