Question

Quizplus · Accepted Answer

A muscle that crosses the spinal joints of the neck laterally with a vertical orientation to its fibers will likely have the action of lateral flexion of the neck at the spinal joints. Examples of such muscles include the sternocleidomastoid and scalene muscles. Flexion and extension of the neck would be produced by muscles that run anteriorly or posteriorly to the spinal joints, respectively. Elevation of the scapula would be produced by muscles that attach to the scapula and run in a vertical direction.
