The lateral neck muscles, also called the lateral vertebral muscles, are a group of muscles that pass obliquely along the lateral sides of the neck. The principal function of these muscles is flexion of the head to varying degrees. Similar to the middle scalene, the main function of the posterior scalene is ipsilateral flexion of the neck when acting from below, and stabilization or elevation of the second rib when acting from above. For example, it contributes to producing an expression of sadness by pulling the corners of the mouth inferiorly. However, the thyrohyoid has an additional function when the hyoid bone is fixed, in which it elevates the larynx. It is also important to know the rotation action of the target muscle when treating it. The interspinales cervicis are innervated by the posterior rami of spinal nerves, and vascularized by branches of the occipital, vertebral and deep cervical arteries. Healthline Media does not provide medical advice, diagnosis, or treatment. They consist of 3 main groups of muscles: anterior, lateral and posterior groups, based on their position in the neck. The function of the cervical transversospinalis muscles is to extend the head and neck during bilateral contraction, and to laterally flex and rotate the head to the same side during unilateral contraction. These include the rectus capitis anterior, rectus capitis lateralis, longus capitis and longus colli. It also allows the ligaments on the neck joints to become more flexible and withstand increased stress to the area. This joint is crucial for movements of your neck – so crucial, in fact, that it accounts for 60% of all your cervical rotation. Our engaging videos, interactive quizzes, in-depth articles and HD atlas are here to get you top results faster. neck of rotation muscle is the main muscle that trapezius stenocleidomastoid splenius It is divided into three parts: The muscle is innervated by the anterior rami of the spinal nerves C2-C6. The muscle bellies both travel towards the hyoid bone and connect via the intermediate tendon, a fibrous tissue sling that is anchored to the superior aspect of the body of hyoid bone. This article will introduce you to the anatomy of the muscles of the neck. The upper cervicals (C1-C2) are responsible for 50% of the rotation that occurs in the head, while the lower cervicals (C3-C7) are responsible for flexion, extension, side bending, and the remaining 50% of rotation. – The muscles of the neck are muscles that cover the area of the neck . Netter, F. (2019). They connect the hyoid bone to the mandible and the base of the skull and form the floor of the oral cavity. The posterior scalene is the smallest and most posterior of the scalene muscles that arises from the posterior tubercles of transverse processes of cervical vertebrae C4-C6. Register now These muscles receive their blood supply via branches of the vertebral, deep cervical and occipital arteries. These muscles are often neglected when warming up for a workout. The longus capitis is a long, flat muscle that arises from the anterior tubercles of transverse processes of vertebrae C3-C6 as four thin muscle strips.

This is commonly one-sided but can occur on both sides of the neck and back. It then extends posterolaterally and inserts into the external surface of the second rib. Generally, the main function of these muscles is positioning of the hyoid bone and movement of the thyroid cartilage of the larynx during vocalization, swallowing and mastication. The anterior scalene muscle is the most anterior of the scalene muscles. The innervation of this muscle comes from the anterior rami of spinal nerves C1 and C2, while its blood supply is provided by branches of the vertebral and ascending pharyngeal arteries. The main function of the trapezius is to produce lateral flexion and contralateral rotation of the head when acting unilaterally, and extension of the head when acting bilaterally. Grounded on academic literature and research, validated by experts, and trusted by more than 1 million users. The heads come together and ascend diagonally to insert onto the mastoid process of the temporal bone. Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. The longus capitis functions as a weak flexor of the head when acting bilaterally, while unilateral contraction of the muscle produces ipsilateral rotation of the head. Kim Bengochea, Regis University, Denver, Author: The function of the digastric muscle depends on its point of action. Atlas of Human Anatomy (7th ed.). Its blood supply is derived from the facial, occipital and posterior auricular arteries. In addition, the sternothyroid muscle can pull the thyroid cartilage away from the hyoid bone and further open the laryngeal inlet, which can aid forced inspiration.

It arises from the anterior tubercles of the transverse processes of vertebrae C3-C6, and inserts onto the scalene tubercle and the superior border of the first rib. Based on the orientation of its fibers, the trapezius is divided into three parts; descending, transverse and ascending part, each of them having distinct attachments. Sinnatamby, C. S., & Last, R. J. Due to their attachments, these muscles mainly produce ipsilateral flexion of the neck. The omohyoid is a narrow muscle that connects the scapula to the hyoid bone. The main function of the longus colli is to flex the neck. In addition, the inferior part of the muscle can produce a weak ipsilateral flexion and contralateral rotation of the neck. These muscles are mainly responsible for the movement of the head in all directions. The scalene muscles are 3 pairs of lateral neck muscles that connect the mid and lower cervical spine with the top of the rib cage. Let’s take a look at them. Most neck pain can be relieved by applying heat or ice, reducing physical activity, stretching the aching area through slow range-of-motion exercises, massage, or by taking over-the-counter pain relievers.
