The rectus capitis posterior major muscle is a small yet vital muscle located at the back of the neck. Tears in this muscle can lead to significant neck pain, stiffness, and functional limitations. Understanding the details—ranging from its anatomy, common causes, and symptoms, to diagnostic tests and treatment options—is essential for effective management and recovery.
Anatomy of the Rectus Capitis Posterior Major
A clear understanding of the anatomy of the rectus capitis posterior major muscle is the basis for recognizing what happens when it is injured. Here are the essential details:
Structure and Location
-
Location:
The rectus capitis posterior major is located in the upper part of the neck, at the back of the head. It plays a crucial role in connecting the skull to the cervical spine. -
SEO Keywords:

Origin and Insertion
-
Origin:
The muscle originates from the spinous process of the axis (the second cervical vertebra, also known as C2). -
Insertion:
It inserts into the medial portion of the inferior nuchal line on the occipital bone of the skull. -
Plain English:
In simpler terms, the muscle starts from a bony knob on the second neck vertebra and attaches to the back base of the skull.
Blood Supply
-
Arterial Supply:
The muscle gets its blood mainly from small branches of the vertebral and occipital arteries. These tiny vessels supply oxygen and nutrients essential for muscle function and healing. -
SEO Keywords:

Nerve Supply
-
Innervation:
The rectus capitis posterior major is innervated primarily by the suboccipital nerve (the dorsal ramus of the first cervical nerve, C1). This nerve controls muscle movement and sensation. -
Plain English:
The suboccipital nerve, coming from the top of the neck, helps the muscle move and feel sensations.
Key Functions
The rectus capitis posterior major muscle is responsible for several important actions:
-
Extension of the Head:
Helps tilt the head backwards. -
Rotation:
Assists in turning the head from side to side. -
Stabilization:
Contributes to maintaining the position of the head and neck. -
Postural Control:
Works with other muscles to support the head’s alignment. -
Fine Motor Control:
Aids in small adjustments of head positioning. -
Assisting Movements:
Works with other suboccipital muscles during complex head movements.

Types of Tears in the Rectus Capitis Posterior Major
Tears in this muscle generally fall into a few categories. Knowing the type of tear is important for treatment:
a. Mild (Grade I) Tear
-
Characteristics:
Minor stretching or microscopic tearing of the muscle fibers without significant loss of strength or range of motion. -
Treatment Outlook:
Often managed with rest, ice, and conservative therapies.
b. Moderate (Grade II) Tear
-
Characteristics:
A more significant tear involving multiple muscle fibers. This may cause noticeable weakness, pain, and reduced neck motion. -
Treatment Outlook:
Typically requires a longer period of rest and targeted physical therapy.
c. Severe (Grade III) Tear
-
Characteristics:
A complete tear of the muscle, leading to severe loss of function, intense pain, and sometimes significant swelling and bruising. -
Treatment Outlook:
May require more intensive interventions, including possible surgical repair if conservative treatments fail. -
