Multiple Choice

A trapezius muscle injury would primarily involve which anatomical region?

Explanation:
The region involved is the neck. The trapezius is a large superficial muscle that spans the back of the neck and upper back, attaching from the skull and cervical spine down to the thoracic spine and into the clavicle and scapula. Because its anatomical location is in the neck and upper back, an injury to this muscle would primarily affect the neck region. The other options (hand, low back, knee) are not where the trapezius resides or functions.
