Question

Quizplus · Accepted Answer

The splenius capitis is a muscle that runs from the lower cervical and upper thoracic vertebrae to the mastoid process of the temporal bone. Its primary action is lateral flexion of the neck and head at the spinal joints. It can also assist in extension and contralateral rotation of the neck and head. It has no action on the scapula, so option B is incorrect. While it can contribute to flexion, it is not its primary action, so option A is also incorrect. Therefore, the best choice is C, lateral flexion of the neck and head at the spinal joints.
