Neck Musculature

Question 1

Levator scapulae (neck)

On each side of neck from occipital to shoulders (posterior)

Answer 1

Integrated function:
Eccentrically decelerate cervical flexion and contralateral cervical rotation and lateral flexion
Eccentrically decelerates scapular depression and upward rotation when the neck is stabilized
Stabilizes the cervical spine and scapulae

Question 2

Sternocleidomastoid (neck)

From upper jaw/ear down to the shoulders (anterior)

Answer 2

Integrated function:
Eccentrically decelerates cervical extension, rotation, and lateral flexion
Isometrically stabilizes the cervical spine and acromioclavicular joint

Question 3

Scalenes (neck)

From the jaw down to ribs 1&2

Answer 3

Integrated function:
Eccentrically decelerates cervical extension, rotation, and lateral flexion
Isometrically stabilizes the cervical spine

Question 4

Longus Coli (neck)

In front of the superior spine/neck to the top ribs

Answer 4

Integrated function:
Eccentrically decelerate cervical extension, lateral flexion, and contralateral rotation
Isometrically stabilizes the cervical spine

Question 5

Longus capitulation (neck)

Top of the occipital bone surrounding the spine into the neck

Answer 5

Integrated function:
Eccentrically decelerates cervical extension
Isometrically stabilizes the cervical spine
