2. WHAT ARE NECK MUSCLES? Neck muscles are bodies of tissue that produce motion in the neck when stimulated. The muscles of the neck run from the base of the skull to the upper back and work together to bend the head and assist in breathing.

3. FUNCTIONS OF NECK MUSCLES The neck muscles serve a variety of functions, including: Elevating your upper ribs so you can inhale. Helping with chewing, swallowing and speaking. Making certain facial expressions. Moving your head, neck and upper back, including your shoulder blades. Stabilizing and supporting your head, neck and spine.

4. 26 There are about 600 muscles in the human body. There are 26 muscles in the neck--10 pairs of 2 and 2 sets of 3, to be precise.

6. The muscles of the neck are muscles that cover the area of the neck. These muscles are mainly responsible for the movement of the head in all directions. They consist of 3 main groups of muscles: anterior, lateral and posterior groups, based on their position in the neck. The musculature of the neck is further divided into more specific groups based on a number of determinants; including depth, precise location and function.

7. Anterior neck muscles The anterior neck muscles are a group of muscles covering the anterior aspect of the neck. Superficial muscles : Platysma, sternocleidomastoid Suprahyoid muscles : Digastric, mylohyoid, geniohyoid, stylohyoid Infrahyoid muscles : Sternohyoid, sternothyroid, thyrohyoid, omohyoid Anterior vertebral muscles : Rectus capitis, longus capitis, longus colli

8. The platysma is a sheet-like muscle that lies within the subcutaneous tissue of the anterior neck, superficial to the investing layer of deep cervical fascia Platysma Superficial muscles The suprahyoid muscles are four muscles located superior to the hyoid bone. They connect the hyoid bone to the mandible and the base of the skull and form the floor of the oral cavity. These muscles include the digastric, mylohyoid, geniohyoid and stylohyoid muscles. Suprahyoid muscles The platysma is a sheet-like muscle that lies within the subcutaneous tissue of the anterior neck, superficial to the investing layer of deep cervical fascia Sternocleidomastoid muscle The mylohyoid is a sheet-like muscle that forms the majority of the floor of the mouth Mylohyoid

9. Digastric is a small paired muscle located in the anterior compartment of the neck. It belongs to a group of muscles called the suprahyoid muscles. Digastric muscle Suprahyoid muscles The Mylohyoideus (Mylohyoid muscle), flat and triangular, is situated immediately above the anterior belly of the Digastricus, and forms, with its fellow of the opposite side, a muscular floor for the cavity of the mouth Mylohyoid muscle Geniohyoid muscle is a short, paired muscle that belongs to the suprahyoid muscle group of the neck. Geniohyoid muscle Stylohyoid is a paired muscle located in the anterior triangle of the neck. It is part of the suprahyoid muscle group which connects the hyoid bone to the mandible and skull. Stylohyoid muscle

10. The sternohyoid is a strap like infrahyoid muscle that connects the hyoid bone with the clavicle and sternum Sternohyoid muscle In frahyoid muscles Omohyoid is a paired muscle located in the anterior region of the neck. It belongs to a group of muscles called infrahyoid muscles, Omohyoid muscle Sternothyroid is a paired strap muscle located in the muscular triangle of the neck. Sternothyroid muscle Thyrohyoid is a small, quadrilateral muscle found in the anterior triangle of the neck. Thyrohyoid muscle

11. The anterior vertebral muscles are a deep group of muscles located just anterior to the cervical vertebral column. These include the rectus capitis anterior, rectus capitis lateralis, longus capitis and longus colli. These muscles are surrounded by the prevertebral fascia of the neck, which is why they are commonly referred to as prevertebral muscles. The principal function of these muscles is flexion of the head to varying degrees. Anterior vertebral muscles

12. Posterior neck muscles Superficial layer : Trapezius, splenius capitis, splenius cervicis. Deep layer : Cervical transversospinales muscles (semispinalis capitis, semispinalis cervicis). Deepest layer : Suboccipital muscles (rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis superior, obliquus capitis inferior). The posterior aspect of the neck is covered by muscles that connect the skull to the spinal column and pectoral girdle.

13. The trapezius is a large, flat, triangular muscle that forms a diamond shape with its contralateral counterpart. Trapezius Superficial layer The superficial muscles of the posterior neck are the splenius muscles; the splenius capitis and splenius cervicis. These muscles also belong to the superficial layer of the deep (intrinsic) back muscles. Splenius muscles

14. The transversospinalis muscles are a large group of muscles that also belong to the deep layer of the intrinsic muscles of the back. This group of muscles comprise the semispinalis, multifidus, and rotatores muscles. All of these muscles are subdivided further according to the region they span. Cervical transversospinalis muscles Deep layer

15. The suboccipital muscles are four small muscles found in the suboccipital region, deep to the semispinalis muscles. Suboccipital muscles Deepest layer

16. Lateral neck (vertebral) muscles 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. These include the anterior, middle and posterior scalene muscles , which extend between the transverse processes of the cervical vertebrae and the upper two ribs. Due to their attachments, these muscles mainly produce ipsilateral flexion of the neck.

17. 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. Anterior scalene muscle 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. Posterior scalene muscle The middle scalene is the largest of the scalene muscles, that arises from the transverse processes of axis (C2) and atlas (C1), and the posterior tubercles of transverse processes of the vertebrae C3-C7 Middle scalene muscle

18. Most neck muscle injuries heal over the course of a few days or weeks with at-home treatments. Your provider may recommend: Heat therapy to relax muscles. Ice or cold compresses to reduce swelling. Massage. Anti-inflammatory medications or muscle relaxants. How are neck muscle injuries treated?
