Levator scapulae muscle

Levator Scapulae Muscle

The Levator Scapulae Muscle (pronunciation: leh-VAY-tor skap-yoo-LAY) is a skeletal muscle situated at the back and side of the neck. As the name suggests, it functions to elevate the scapula, the bone that connects the humerus (upper arm bone) with the clavicle (collar bone).

Etymology

The term 'Levator Scapulae' is derived from Latin, where 'Levator' means 'to lift' and 'Scapulae' refers to the 'shoulder blade'. Thus, the name directly describes the primary function of the muscle.

Anatomy

The Levator Scapulae originates from the transverse processes of the first four cervical vertebrae and inserts into the medial border of the scapula. It is innervated by the dorsal scapular nerve and the cervical spinal nerves C3 and C4.

Function

The primary function of the Levator Scapulae is to elevate the scapula. It also contributes to the downward rotation of the scapula, tilt of the glenoid cavity, and lateral flexion and rotation of the neck when the scapula is fixed.
