Challenging neck muscles Flashcards
Trapezius origin
External occipital protuberance, medial portion of the superior nuchal line of the occiput, ligamentum nuchae, spinous processes of C7-T12
The upper traps rotate the head and neck to which side?
The opposite side
Actions of the anterior scalene
Unilaterally side bends the neck and rotates to the opposite side. Bilaterally elevates the ribs and flexes the head and neck.
Actions of the middle scalene
Unilaterally sidebends and rotates the head to the opposite side. Bilaterally elevates the ribs.
Posterior scalene actions
Unilaterally side bend and rotate to the opposite side. Bilaterally elevate the ribs.
Semispinalis capitis origin
Transverse processes of C4 to T5
Semispinalis capitis insertion
Between the superior and inferior nuchal lines of the occiput
Semispinalis capitis actions
Extend the head and neck
Multifidi actions
Unilaterally rotate to the opposite side. Bilaterally extend
Multifidi origins in the cervical spine
Transverse processes
Multifidi insertions
The spinous processes 2 to 4 vertebrae above.
Rotatores actions
Unilaterally rotate to the opposite side. Bilaterally extend.
Rotatores origin
Transverse processes
Rotatores insertion
Spinous processes 1-2 vertebrae above
Longus capitis origin
Transverse processes of C3-C6
Longus capitis insertion
Inferior surface of the occiput
Longus capitis actions
Unilaterally side bend and rotate to the same side. Bilaterally flex the head and neck.
Longus colli origin
Bodies of C5 to T3, transverse processes of C3-C5
Longus colli insertion
Tubercle on the anterior arch of the atlas, the bodies of C2-4 and the transverse processes of C5 and 6.
Longus colli actions
