Press directly back to press your anterior scalene directly against your vertebral column and release pressure underneath your fingertips.
Where is the scalene?
The scalene muscles are located deep in relation to the sternocleidomastoid muscle, lateral to the cervical spine, connecting the vertebrae to the first two ribs. The deep fascia or prevertebral fascia envelop the scalene muscles.
Where is the middle scalene?
Middle Scalene, AKA Scalenus Medius (Latin: musculus scalenus medius), is the largest and longest muscle in the scalene group of lateral neck muscles. Often penetrated by the dorsal scapular and long thoracic nerves, it is deeply placed, lying behind Sternocleidomastoid.
