Neck accessory muscles play a vital role in stabilizing the head, supporting breathing, and enabling many everyday movements. When these muscles suffer a tear, it can cause pain, stiffness, and reduced mobility.
Neck accessory muscles are the supporting muscles in your neck that assist with head movements and even help with breathing. They include well-known muscles like the sternocleidomastoid, trapezius, scalene muscles, and sometimes the levator scapulae. These muscles work together to allow you to turn, tilt, and stabilize your head.
A muscle tear occurs when the fibers of a muscle stretch too far or are ripped. This can range from a mild strain (where the fibers are stretched) to a complete tear (where many fibers are disrupted). Such injuries may result from sudden trauma, overuse, or other causes described later.
Anatomy of Neck Accessory Muscles
An understanding of the basic anatomy of your neck accessory muscles can help explain why a tear might happen and how it affects your movement.
Key Muscles Involved
-
Sternocleidomastoid (SCM)
-
Location: Runs along each side of the neck.
-
Origin: Begins at the manubrium of the sternum and the medial clavicle.
-
Insertion: Attaches to the mastoid process of the temporal bone and the lateral end of the superior nuchal line on the skull.
-
Blood Supply: Mainly supplied by branches of the occipital and superior thyroid arteries.
-
Nerve Supply: Innervated by the accessory nerve (cranial nerve XI) and some branches from the cervical plexus.
-
-
Upper Trapezius
-
Location: Covers the back of the neck and upper back.
-
Origin: Starts from the occipital bone and the ligamentum nuchae.
-
Insertion: Attaches along the lateral third of the clavicle and the acromion of the scapula.
-
Blood Supply: Receives blood from the transverse cervical artery.
-
Nerve Supply: Also innervated by the accessory nerve (cranial nerve XI).
-
-
Scalene Muscles (Anterior, Middle, and Posterior)
-
Location: Positioned on the lateral side of the neck.
-
Origin: Arise from the cervical vertebrae (commonly C3–C6).
-
Insertion: Attach to the first and second ribs.
-
Blood Supply: Typically supplied by branches of the thyroid and vertebral arteries.
-
Nerve Supply: Innervated by the cervical spinal nerves.
-
-
Levator Scapulae (sometimes considered)
-
Location: Found along the side and back of the neck.
-
Origin: Arises from the transverse processes of the upper cervical vertebrae.

Nerve Supply: Innervated by the dorsal scapular nerve and cervical nerves.
-
Main Functions of Neck Accessory Muscles
-
Neck Flexion: Bending the head forward (as when looking down).
-
Neck Extension: Bending the head backward (as when looking up).
-
Lateral Flexion: Tilting the head from side to side.
-
Neck Rotation: Turning the head from one side to the other.
-
Shoulder Elevation: Raising the shoulders (a key role of the trapezius).
-
Accessory Respiratory Function: Assisting in breathing, particularly during physical exertion (a role played by the scalene muscles).
Types of Neck Accessory Muscle Tears
Muscle tears can be classified by their severity or the mechanism by which they occur. The main types are:
-
Grade I (Mild Strain):
Minor stretching or microscopic tears in the muscle fibers. Usually results in mild pain and limited dysfunction. -
Grade II (Partial Tear):
A partial tear where a significant number of muscle fibers are disrupted. This type causes more pain, swelling, and weakness. -
Grade III (Complete Tear):
A complete rupture of the muscle or tendon. It is the most severe, often resulting in significant loss of function and may require surgical repair. -
Traumatic vs. Overuse Tears:
-
Traumatic Tears occur suddenly from an injury such as a fall, accident, or impact.
-
Overuse Tears develop gradually over time due to repetitive stress or strain (for example, from poor posture or repetitive motion during work or sports).
-
Causes of Neck Accessory Muscle Tears
Many factors can increase the risk of a tear in the neck accessory muscles. Here are 20 common causes:
-
