The scalene muscles are a group of three muscles on each side of the neck, identified as the anterior, the middle, and the posterior. They are innervated by the third to the eighth cervical spinal nerves (C3-C8). The anterior and middle scalene muscles lift the first rib and bend the neck to the side they are on. The posterior scalene lifts the ...

The scalene muscles (Latin: musculi scaleni) are three paired muscles found in the lateral compartment of the neck. Therefore, they are also known as the lateral neck muscles. The scalene muscles stretch between the transverse processes of the cervical vertebrae and the first and second ribs.

Middle scalene or 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.

The widths of the scalenus medius muscles at their insertion were between 10 and 20 mm with a mean of 15.5 mm. Fifty percent of the scalenus posterior muscles arose from C4 to C6 and 50% arose from C5 to C6. Conclusions: Variations were found in the attachments and the size of the scaleni muscles.
