2023年11月3日 · When the costal attachment of the scalenus posterior muscle is fixed, the unilateral contraction of the muscle results in the ipsilateral lateral flexion of the neck. When the vertebral attachment is fixed, the muscle helps stabilize or elevate the 2nd rib during respiration.
Scalene muscles - Wikipedia
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 ...
