The sternocleidomastoid is a large, two-headed muscle of the neck. Superficial layer: Trapezius, splenius capitis, splenius cervicisĭeep layer: Cervical transversospinales muscles (semispinalis capitis, semispinalis cervicis)ĭeepest layer: Suboccipital muscles (rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis superior, obliquus capitis inferior) Scalene muscles: Anterior scalene, middle scalene, posterior scalene muscles
Infrahyoid muscles: Sternohyoid, sternothyroid, thyrohyoid, omohyoidĪnterior vertebral muscles: Rectus capitis, longus capitis, longus colli Suprahyoid muscles: Digastric, mylohyoid, geniohyoid, stylohyoid Superficial muscles: Platysma, sternocleidomastoid This article will introduce you to the anatomy of the muscles of the neck.Ī large group of muscles in the cervical area, responsible for the movement of the head in all directions The muscles of the neck are closely related to a number of important structures that pass between the thorax and the head, including major blood vessels, nerves and elements of the respiratory and gastrointestinal systems. For example, the muscles in the posterior neck are responsible for extension of the neck. The position of a muscle or group of muscles in the neck generally relates to the function of the muscles. The musculature of the neck is further divided into more specific groups based on a number of determinants including depth, precise location and function. They consist of 3 main groups of muscles: anterior, lateral and posterior groups, based on their position in the neck.
These muscles are mainly responsible for the movement of the head in all directions. The muscles of the neck are muscles that cover the area of the neck.
