Facial Expressions and the Muscles of the Neck

muscles of the neck

If you want to know how to make your facial expressions look better, you should know about the muscles of the neck. You can learn about them by reading this article. We’ll cover the Origin, Location, and Function of each muscle. Let’s start with the platysma muscle, which is a large superficial muscle that inserts on the skin of the lower jaw. It’s responsible for facial expressions and is a member of the platysma muscle group.

Functions

The neck is a complex structure, and the neck muscles perform many different functions. They help balance the head, rotate it, and flex it. The main muscle that controls head movement is the sternocleidomastoid, which forms a triangle between the anterior and posterior parts of the neck. The other major muscles in the neck are the subclavius and suprahyoids. The latter two muscles work together to stabilize the collarbone and move the hyoid bone.

Origin

The neck is a complex structure that consists of a series of muscle groups. Each muscle group helps to control the head’s position and function. They are located between the larynx and the hyoid bone, which serves as a foundation for the movements of the tongue and the head. Muscles in the neck are divided into three groups according to their position in the neck, depth, and function.

Functional group

There are several functional groups of neck muscles. The posterior group focuses on head movements, while the anterior group is responsible for stabilizing the vertebral column. They are classified according to lengths of the fascicles, which are usually called’splenius’ muscles. The splenius capitis and cervicis insert onto the cervical and head regions. These muscles are capable of laterally flexing, extending and rotating the head. The back group consists of large complex muscles that move the head, shoulders, and vertebral column.

Location

There are several important differences between the anterior and posterior position of the muscles in the neck. Generally, the muscles of the posterior neck extend the neck. The muscles of the anterior and posterior neck are closely related to major blood vessels, nerves, and elements of the respiratory and gastrointestinal systems. This article explains the anatomy of the neck muscles and the relationship between them. There are four groups of neck muscles: superficial, mid-level, and deep. The anterior group of muscles includes the digastric and sternocleidomastoid. The posterior group includes the suprahyoid muscles.

Pain

Neck pain is one of the most common forms of injury. The muscles in the neck are composed of bundles of myofibrils, which house contractile proteins that perform the mechanics of muscle contraction. Inflammation or anatomical damage can impinge on these nerve roots, causing pain. The pain can be sharp or dull, intermittent, constant, or fleeting. In addition to pain, neck injuries may result in numbness, tingling, or weakness of the arm.

Treatment

There are several types of muscle strains and injuries of the neck. Some strains occur due to lifting heavy objects or using the neck muscles in unusual ways. Others may result from prolonged sitting or prolonged use of the neck. No matter the cause, neck muscle strains can occur to anyone. A doctor will perform a physical examination, and ask questions to determine the severity and underlying medical conditions. In some cases, physiotherapy may be required to treat neck pain.
