Neck Strain Neck Strain Overview. Neck strain is injury to the muscles and tendons that support and move the head and neck. The neck is susceptible to injury because it is capable of extensive range of motion. It is, as a result, less stable that many other body areas. In addition, the neck muscles are affected by the motion of nearly all other areas of the body. The neck contains many vital anatomic structures, the most critical being the airway (breathing tube), the spinal cord, and the blood vessels that supply the brain.

Sternocleidomastoid Muscle The sternocleidomastoid is a long muscle in the side of the neck that extends up from the thorax to the base of the skull behind the ear. When the sternocleidomastoid on one side contracts, the face is turned to the opposite side. When both muscles contract, the head is bent toward the chest. If the immovable end is fixed in position by other muscles, it can raise the sternum (breastbone) - an action which aids in forceful inhalation of air. The sternocleidomastoid is a long muscle in the side of the neck that extends up from the thorax to the base of the skull behind the ear.

Computer Neck Syndrome: Postural Causes of a Common Malady What many do not consider is that a chronically tight biceps will pull on the scapula, or shoulder blade, forcing opposing muscles to counter. As a tight biceps pulls the shoulder blade down, the muscles of the neck—upper traps, levator, scaps and scalenes—will resist, causing tightness, hypertonicity, and even spasm.

Splenius Capitis Muscle Splenius Capitis Muscle. Introduction. The splenius capitis is one of the deep muscles of the back of the neck. It acts as an extensor of neck, lateral flexor and assists in rotation of the neck, and forms part of the floor of the posterior triangle of the neck. In this article we will discuss the gross and functional anatomy of the splenius capitis.

Splenius Capitis Muscle The muscle lies deep to the sternocleidomastoid in its superior portion, and deep to trapezius in its inferior portion. The muscle acts as a shaker of the head, it causes neck extension and lateral flexion. Other muscles that extend and rotate the head include the semispinalis capitis and semispinalis cervicis (also laterally flexes the head). The superior portion of trapezius also acts as a lateral flexor of the neck.
