Types of Muscles in the Neck

The muscles of the neck, classified into anterior, posterior, and lateral/vertebral groups, collectively contribute to the maintenance of a high quality of life. They facilitate essential functions such as head movement, head support, respiration, swallowing, speech, posture maintenance, protection of vital structures, and gaze stabilization.

Their coordinated actions ensure that we can perform daily activities comfortably and effectively, while also safeguarding critical anatomical structures in the neck region.

Anterior

Sternocleidomastoid (SCM) muscles:

• Head movement: The SCM muscles, one on each side of the neck, allow for flexion, extension, and rotation of the head. These movements are essential for everyday activities such as nodding, looking up and down, and turning the head to check surroundings while walking or driving.
• Respiration: SCM muscles assist in deep inhalation by lifting the sternum and ribcage. This function enhances the overall capacity of the lungs, supporting efficient respiration.

Suprahyoid muscles (digastric, mylohyoid, geniohyoid, stylohyoid): 

• Swallowing and speech: These muscles play a crucial role in swallowing and speaking. They elevate the hyoid bone and larynx during the swallowing process, preventing food from entering the airway and aiding in clear articulation during speech.

Infrahyoid muscles (sternohyoid, omohyoid, thyrohyoid, sternothyroid):

• Swallowing and speech: Infrahyoid muscles assist in depressing the hyoid bone and larynx during swallowing. They contribute to precise control over the passage of food and air.
• Protection of vital structures: These muscles help shield the trachea and thyroid gland, contributing to the protection of these vital structures.

Posterior

Trapezius muscle:

• Head support and movement: The trapezius muscle plays a critical role in head and neck support. It stabilizes the scapulae and cervical spine, helping maintain an upright posture and balance the weight of the head.
• Gaze stabilization: The upper fibers of the trapezius assist in tilting and rotating the head, aiding in the stabilization of gaze during activities such as reading or using a computer.

Levator scapulae muscle:

• Head movement: The levator scapulae muscle elevates the scapula, which is essential for head movement. It allows the head to tilt to one side, aids in neck extension, and assists in rotating the head when turning.
• Suboccipital muscles (rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis inferior, obliquus capitis superior):Head movement and posture: These small muscles are responsible for subtle head movements and play a vital role in maintaining proper head and neck posture. They contribute to head extension and rotation.

Lateral/Vertebral

Scalene muscles (anterior, middle, and posterior scalene):

• Respiration: Scalene muscles assist in forced inhalation by elevating the upper ribs. This action increases the lung’s capacity during strenuous activities, helping to maintain adequate oxygen intake.
• Head support and posture: These muscles also help stabilize the cervical spine and maintain an upright head and neck posture.

Prevertebral muscles (longus colli, longus capitis, rectus capitis anterior, rectus capitis lateralis)

• Head movement and posture: Prevertebral muscles play a significant role in head flexion and maintaining cervical spine stability. They are essential for activities that involve looking down, such as reading or working on handheld devices.
• Protection of vital structures: These muscles provide a protective layer around the cervical spine and its associated nerves and blood vessels, safeguarding them from external trauma.

Symptoms of Disorders Affecting Neck Muscles

It’s essential to remember that chronic symptoms in the neck, including stiffness, pain, and swelling, should be evaluated by a healthcare professional for an accurate diagnosis and appropriate management. These symptoms can be indicative of various underlying conditions, and early intervention can help improve the quality of life and prevent further complications.

Stiffness

• Reduced range of motion: One of the primary symptoms of chronic neck muscle conditions is stiffness, which leads to a reduced range of motion in the neck. Affected individuals may find it challenging to turn their heads fully or tilt them in different directions.
• Difficulty in maintaining correct posture: Chronic stiffness often results in difficulty maintaining an upright posture. Individuals may develop a forward head posture (where the head juts forward) or have limited ability to hold their heads in a neutral position.
• Muscle tightness: Tightness and tension in the neck muscles are common symptoms. Individuals may experience a constant feeling of muscle tightness, making it uncomfortable to relax the neck muscles fully.

Pain

• Persistent discomfort: Chronic neck muscle conditions are frequently associated with persistent neck pain. The pain may be dull, aching, or sharp, and it can vary in intensity.
• Radiating pain: Pain from the neck muscles can radiate to the shoulders, upper back, and even down the arms. This may result in a sensation of burning or tingling.
• Pain aggravated by movement: Activities such as turning the head, lifting, or carrying objects may exacerbate neck pain in individuals with chronic muscle issues.

Swelling

• Visible swelling: In some chronic neck muscle conditions, individuals may notice visible swelling or puffiness in the neck region.
• Tenderness to touch: Swollen neck muscles can be tender and sensitive to the touch, causing discomfort when pressure is applied.
• Limited mobility: Swelling can restrict the movement of the neck and cause a feeling of tightness and pressure in the affected area.
