Overview

The levator scapulae is a long and slender muscle. Although the levator scapulae is geographically associated with the muscles of the back, it is functionally more similar to the scapular muscles such as the rhomboid major, minor, and serratus anterior.

Origin

TP C1-C4

Insertion

Superior angle of the scapula

Innervation

Action

  • STJ: Elevates and downwardly rotates scapula
  • C/S: Extends and I/L lateral flexion

The levator scapula coactivates with the scapulothoracic upward rotators to counter eachother’s frontal plane rotation and to result in pure elevation.

Notes

Paralysis

Paralysis of the levator scapulae will result in a sagging shoulder girdle.
