What is the proximal attachment of the levator scapulae?

The proximal attachment of the levator scapulae is found at the transverse processes of the first four cervical vertebrae (CV1-CV4). This muscle originates from these specific bony structures, which are positioned laterally on the neck. By attaching to the transverse processes, the levator scapulae can effectively lift the scapula (shoulder blade) and participate in movements like shrugging the shoulders and tilting the head to the side.

The other answer options refer to different anatomical landmarks on the scapula and the shoulder girdle. The superior angle of the scapula, for instance, is where the levator scapulae exerts its action, but this is not where it attaches; instead, it connects at the cervical vertebrae. Similarly, the spine of the scapula and the clavicle and acromion are not relevant to the origin of the levator scapulae. This muscle’s attachment points are crucial for understanding its role in shoulder movement and neck stability.
