Levator scapulae muscle

Location

The levator scapulae takes its origin from the posterior tubercles of the tranverse processes of the C1 to C4 vertebrae. It is inserted into the superior part of the medial border of the scapula.

Action

The levator scapulae elevates the scapula and tilts its glenoid cavity by rotating the scapula in the inferior direction.

Innervation

The levator scapulae is innervated by :

• cervical nerve (C3, C4)
• dorsal scapula nerve (C5)

Blood supply

The levator scapulae is supplied by the dorsal scapular artery
