The levator scapulae is a slender [1]: 910 skeletal muscle situated at the back and side of the neck. It originates from the transverse processes of the four uppermost cervical vertebrae ; it inserts onto the upper portion of the medial border of the scapula .
Laterocollis is the tilting of the head from side to side. This is the "ear-to-shoulder" version. This involves many more muscles: ipsilateral sternocleidomastoid, ipsilateral splenius, ipsilateral scalene complex, ipsilateral levator scapulae, and ipsilateral posterior paravertebrals. The flexion of the neck (head tilts forwards) is anterocollis.
The dorsal scapular nerve is at risk for intraoperative injury when detaching the rhomboid and levator scapulae insertions due to its proximity to the medial scapular border. [15] This is of particular concern because the dorsal scapular nerve innervates all three muscles transferred in the Eden–Lange procedure.
Dorsal scapular nerve syndrome can be caused by nerve compression syndrome.A winged scapula is the most common symptom. [7] Shoulder pain may occur. [7] It causes weakness in rhomboid major muscle, rhomboid minor muscle, and levator scapulae muscle. [7]
Damage results in an inability to shrug the shoulders or raise the arm above the head, particularly due to compromised trapezius muscle innervation. The external jugular vein's superficial location within the posterior triangle also makes it vulnerable to injury.
The scapula plays an important role in shoulder impingement syndrome. [8] It is a wide, flat bone lying on the posterior thoracic wall that provides an attachment for three different groups of muscles. The intrinsic muscles of the scapula include the muscles of the rotator cuff- the subscapularis, infraspinatus, teres minor and supraspinatus. [9]
The posterior axioappendicular muscles are described as two sub-groups: [1] [3] Superficial Posterior Axioappendicular muscles (or the extrinsic shoulder muscles) Trapezius; Latissimus dorsi; Deep Posterior Axioappendicular muscles (or the intrinsic shoulder muscles) Levator scapulae; Rhomboid minor; Rhomboid major
Anatomical terms of muscle [ edit on Wikidata ] The levatores costarum ( / ˌ l ɛ v ə ˈ t ɔːr iː z k ə ˈ s t ɛər ə m / ), twelve in number on either side, are small tendinous and fleshy bundles, which arise from the ends of the transverse processes of the seventh cervical and upper eleven thoracic vertebrae
