An example of trapezius function is an overhead press. When activating together, the upper and lower fibers also assist the middle fibers (along with other muscles such as the rhomboids) with scapular retraction/adduction. The trapezius also assists in abduction of the shoulder above 90 degrees by rotating the glenoid upward.

In 2007, a study identified a gene that was proposed to be responsible for dog size. The study found a regulatory sequence next to the gene Insulin-like growth factor 1 (IGF1), which, together with the gene and regulatory sequence, "is a major contributor to body size in all small dogs." Two variants of this gene were found in large dogs ...
Shoulder shrug exercises can help to strengthen neck and shoulder muscles which in results help to reduce neck pain. The core muscle that gets activated during shoulder shrugs are trapezius. [ 7 ]
The spinal component of the accessory nerve provides motor control of the sternocleidomastoid and trapezius muscles. [8] The trapezius muscle controls the action of shrugging the shoulders, and the sternocleidomastoid the action of turning the head. [8] Like most muscles, control of the trapezius muscle arises from the opposite side of the ...
All dogs (and all living Canidae - wolves, foxes, and wild dogs) possess a similar ligament connecting the spinous process of their first thoracic (or chest) vertebrae to the back of the axis bone (second cervical or neck bone), which supports the weight of the head without active muscle exertion, thus saving energy.
