Cat Musculature Origin Insertion Function. The scalenes act as accessory muscles of respiration and perform flexion at the neck. They are a set of three muscles (anterior, middle and posterior scalenes) lying deep to the sternocleidomastoid.
Action: Flexion of the cervical spine, Lateral flexion of cervical spine, elevation of.
