What does the trapezius do to your shoulder?
The trapezius stabilizes the shoulder blades and also facilitates shoulder and neck movement. The superior or upper segment of the muscle helps elevate the shoulder blades. The upper trapezius also helps rotate and tilt the neck.
What activities use the trapezius?
The trapezius muscle is a postural and active movement muscle, used to tilt and turn the head and neck, shrug, steady the shoulders, and twist the arms. The trapezius elevates, depresses, rotates, and retracts the scapula, or shoulder blade.
What is the function of the trapezius muscle quizlet?
Weakness: Allows the scapula to ride upward and tilt forward, with depression of the coracoid process. If the upper trapezius is tight, it helps to pull the scapula upward and acts as an opponent to a weak lower trapezius.
Are traps considered back or shoulders?
While the traps allow shoulder movement and attach to the scapula, they are considered part of the back. It’s a three-part muscle that attaches at the base of your skull and continues down to the middle of your spine.
Do traps protect neck?

What is the main function of the trapezius?

Where are the trapezius muscles located in the body?
The Anatomy of the Trapezius Muscle. The trapezius muscle is a large muscle bundle that extends from the back of your head and neck to your shoulder. It is composed of three parts: the upper trapezius, middle trapezius, and the lower trapezius.
When does the descending part of the trapezius contract?
Bilateral contraction of the descending part of trapezius (i.e. when both left and right muscles contract) causes an extension of the head and neck.
What happens to your trapezius muscles when you work at a desk?
If you work at a desk, or your job involves a lot of driving, you likely know this firsthand. When the shoulder girdle is pulled up in a constant and chronic way, it leads to misalignment that can make the upper traps chronically tight. The result may well be a pain, limited movement and a loss of neck flexibility.
What causes tightness in the trapezius in the neck?
Tightness and pain: Poor posture, such as sitting at a desk with hunched shoulders for long periods of time, can cause tightness in the traps. People who sit at a computer for several hours a day have a higher risk of chronic pain in the neck and shoulders.
