Levator scapulae muscle
The levator scapulae muscle is a skeletal muscle situated at the back and side of the neck. It is primarily responsible for the elevation of the scapula.
Anatomy[edit]
The levator scapulae muscle originates from the transverse processes of the first four cervical vertebrae (C1-C4). It inserts into the superior part of the medial border of the scapula.
Innervation[edit]
The muscle is innervated by the cervical nerves (C3, C4) and the dorsal scapular nerve (C5).
Blood Supply[edit]
The dorsal scapular artery supplies blood to the levator scapulae muscle.
Function[edit]
The primary function of the levator scapulae muscle is to elevate the scapula. It also assists in the downward rotation of the scapula and helps in the lateral flexion of the neck.
Clinical Significance[edit]
The levator scapulae muscle can be a source of neck pain and discomfort, often due to poor posture or muscle strain. Conditions such as levator scapulae syndrome can arise from overuse or injury to this muscle.
