Neck accessory muscles play a crucial role in supporting head movement, maintaining posture, and, in some cases, assisting with breathing. When these muscles become strained or injured, pain and discomfort can significantly impact daily life. In this article, we cover all you need to know—from the detailed anatomy of these muscles to the many potential causes, the symptoms you might experience, and the wide range of diagnostic tests and treatment options available.
Anatomy of the Neck Accessory Muscles
Understanding the detailed anatomy of the neck accessory muscles is essential for grasping why and how pain may occur. Below, we explain the location, origin, insertion, blood supply, nerve supply, and key functions of the most common accessory muscles in the neck.
Common Neck Accessory Muscles
Sternocleidomastoid (SCM)
-
Location: Runs along the side of the neck.
-
Origin: Has two parts; one originates at the manubrium (upper chest bone) and the other from the medial part of the clavicle.
-
Insertion: Attaches to the mastoid process (a bony prominence behind the ear) and the lateral superior aspect of the skull.
-
Blood Supply: Primarily from branches of the occipital and superior thyroid arteries.
-
Nerve Supply: Receives innervation from the accessory nerve (cranial nerve XI) and cervical nerves (C2–C3).
-
Functions:
-
Rotates the head.
-
Flexes the neck.
-
Assists in lifting the chest during forced inspiration (acting as an accessory respiratory muscle).
-
Trapezius (Upper Fibers)
-
Location: Extends from the back of the neck down to the shoulders.
-
Origin: Begins at the external occipital protuberance and the ligamentum nuchae.
-
Insertion: Inserts along the outer third of the clavicle.
-
Blood Supply: Primarily the transverse cervical and occipital arteries.
-
Nerve Supply: Innervated by the accessory nerve (cranial nerve XI) with contributions from cervical spinal nerves.
-
Functions:
-
Elevates and retracts the scapula.
-
Provides support for the head and neck.
-
Helps maintain proper posture.
-
Scalene Muscles (Anterior, Middle, and Posterior)
-
Location: On the lateral aspect of the neck.
-
Origin: Arise from the cervical vertebrae (typically C2–C7).
-
Insertion: Attach to the first and second ribs.
-
Blood Supply: Supplied by branches of the costocervical trunk.
-
Nerve Supply: Innervated by cervical spinal nerves.
-
Functions:
-
Assist in elevating the first and second ribs during breathing.
-
Contribute to lateral flexion of the neck.
-
Levator Scapulae
-
Location: Runs along the side and back of the neck.
-
Origin: Begins from the transverse processes of the upper cervical vertebrae (C1–C4).
-
Insertion: Inserts at the superior angle of the scapula (shoulder blade).
-
Blood Supply: Receives blood from the transverse cervical artery.
-
Nerve Supply: Innervated by the dorsal scapular nerve (C5) and cervical nerves.
-
Functions:
-
Elevates the scapula.
-
Helps in neck movement and stabilization.
-
Additional Muscles:
Muscles such as the splenius capitis and semispinalis capitis also contribute to head extension, rotation, and posture. Although not always classified as primary accessory muscles, they can be involved when pain is present.
Key Functions of the Neck Accessory Muscles
-
Head Rotation: Turning the head side to side.
-
Head Flexion: Bending the head forward.
-
Head Extension: Lifting the head backward.
-
Lateral Flexion: Tilting the head from one side toward the shoulder.

Types of Neck Accessory Muscles Pain
Neck accessory muscle pain can be categorized based on its duration, source, and quality. Common types include:

Acute Pain: Sudden onset usually due to a strain or injury, often resulting from an accidental movement or a sudden jolt (e.g., whiplash).
-
Chronic Pain: Long-lasting pain that may continue for months, often linked to poor posture or repetitive stress.
-
Myofascial Pain Syndrome: Involves trigger points or “knots” in the muscles that can refer pain to other parts of the neck, shoulder, or head.
-
Referred Pain: Pain that originates in one area but is felt in another; for instance, issues in the cervical spine can lead to pain in the accessory muscles.
-
Postural-Related Pain: Associated with prolonged periods of poor posture, such as extensive computer or smartphone use.
