The rotator cervical muscles (musculos rotator cervicis) allow our body to turn our head to the right and left, as well as tilt it forward. Their main function is to provide neck flexibility.
The rotator cuff muscles are divided into external and internal. External muscles: - short extensors of the head - fourth order rotator muscles are located behind (they are divided into posterolateral and transverse); - The levator scapulae muscle is the second largest superior rotator muscle. The rhomboid major and minor muscles extend onto the clavicle and enter the acromiocleidoid joint. These rotators are attached to the cartilage of the II-IV ribs, the cartilage in turn is involved in the II costoclavicular joint; - the pectoralis minor and major (serratus anterior) muscles are classified as the third largest rotators of the head of the second order; the muscles stretch to the lateral surface of the ribs to the angles where the ribs join the sternum.
Intrinsic muscles: Longus colli and infrahyoid muscles are involved in the second rotator cuff and are called external rotators. The first muscle connects the skull to the larynx, the second borders the sublingual
