Introduction
There are many muscles in the neck, primarily including the splenius cervicis, cervical oblique muscles, and sternocleidomastoid muscle. Additionally, there are the infrahyoid muscles located below the neck, which originate from the hyoid bone and cervical vertebrae and insert into the cervical vertebrae and skull. These muscles work together in a coordinated manner, enabling various movements of the head and neck through contraction and relaxation.
There are many muscles in the neck, primarily including the cervical latissimus dorsi, neck oblique muscles, and sternocleidomastoid muscle.
1. Cervical Latissimus Dorsi
Located on the posterior side of the neck, this muscle originates from the cervical and thoracic vertebrae and inserts into the scapula and clavicle. Its main function is to control movements of the head and neck.
2. Neck Oblique Muscles
Located on the lateral sides of the neck, these consist of the superior and inferior oblique muscles. They originate from the cervical and thoracic vertebrae and insert into the skull and clavicle. Their primary role is to control lateral movements of the head and neck.
3. Sternocleidomastoid Muscle
Located at the front of the neck, it originates from the sternum and clavicle and inserts into the cervical vertebrae and skull. Its main functions include controlling forward and backward tilting as well as rotation of the head and neck.
In addition, there are the hyoid muscles, located beneath the neck, originating from the hyoid bone and cervical vertebrae and inserting into the cervical vertebrae and skull. These muscles work together in a coordinated manner, enabling various movements of the head and neck through contraction and relaxation. At the same time, these muscles require appropriate exercise and care to maintain their health and functionality.
