The levator scapulae muscle primarily elevates and rotates the scapula (shoulder blade) downward and inward, allowing for movements such as shrugging the shoulders. It can also contribute to lateral flexion of the neck when acting unilaterally.

What does it mean when the term levator is part of the descriptive term for a muscle's action?
When the term "levator" is part of a muscle's action, it typically indicates that the muscle is involved in lifting or elevating a specific body part. For example, the levator scapulae muscle elevates the scapula (shoulder blade), while the levator anguli oris muscle elevates the angle of the mouth when smiling.
What are the antagonists of the rhomboids?
The main antagonists of the rhomboid muscles are the serratus anterior and pectoralis minor. These muscles work in opposition to the rhomboids to perform movements like protraction and downward rotation of the scapula. Strengthening these antagonist muscles can help maintain shoulder stability and balance in the upper body.
What is shoulder elevation?
Shoulder elevation refers to the movement of raising the shoulders towards the ears. It primarily involves the contraction of the upper trapezius muscles. Shoulder elevation is commonly seen in movements such as shrugging or lifting heavy objects.
What connects to scapulae?
The scapulae, also known as shoulder blades, connect to the clavicles (collarbones) at the acromioclavicular joint. Muscles such as the trapezius, deltoid, and rotator cuff muscles also connect to the scapulae to help move and stabilize the shoulder joint.
What is Between the scapulae?
Between the scapulae refers to the space located between the two shoulder blades or shoulder bones. This area is part of the upper back and is important for the attachment of various muscles that help with shoulder movement and stability. It is also a common area for muscle tension and trigger points.
What is the action of the levitor scapulae muscle?
Raises the scapula at the Scapulothoracic Joint or inclines neck to corresponding side if the scapula is fixed
What muscle rotates the neck?
Levator scapulae
Synergistic muscles in the levator scapulae?
Trapezius 1
What are the prime movers of scapular elevation?
Levator scapulae and trapezius
What muscle is the prime mover for shoulder abduction?
Trapezius and Levator Scapulae
What deep muscle protract the scapula during punching?
levator scapulae
What is superior to the levator scapulae?
I would imagine that would be the trapezius muscles.
What is the synergist of the trapezius in scapular elevation?
The synergist of the trapezius in scapular elevation is the levator scapulae muscle. It works together with the trapezius to elevate the scapula and assist in movements like shrugging the shoulders.

What 3 muscles extend the shoulder?
Upper fibres of the trapezius, rhomboid minor and major and levator scapulae.
What is the antagonist muscle of the Levator Scapulae?
The serratus anterior is one, and the lower trapezius muscles are the others. The SA muscles pull the scapulae downward and anteriorly while the lower traps pull downward and medially.
What is the origin of the levator scapulae?
the origlevator capulae is the transverse process and cervical vertebrae [ref: nath & martini- anatomy and physiology tetbook]
