GENERAL INFORMATION
The Longus Capitis muscle is located in the deep anterior portion of the neck. Which plays a vital role in neck flexion and head stabilisation. This muscle is part of the prevertebral group, which supports the cervical spine and helps facilitate smooth movements of the head and neck. It extends from the upper cervical vertebrae to the base of the skull, making it essential for head control. The Longus Capitis is crucial in preventing neck pain and maintaining posture. Longus capitis also provides the foundational support needed for activities like nodding, looking down, and stabilising the head during rotation.
ORIGIN
The Longus Capitis originates from the anterior tubercles of the transverse processes of the third to sixth cervical vertebrae (C3 to C6). Consequently, this origin provides a stable base for its action, thereby allowing it to work effectively in head movements.
INSERTION POINT
The muscle inserts into the basilar part of the occipital bone, just anterior to the foramen magnum. As a result, this insertion point allows the Longus Capitis to effectively influence head movements and stabilise the base of the skull.
MAJOR ARTERIES
The blood supply for the Longus Capitis primarily comes from the vertebral artery and, additionally, the ascending pharyngeal artery. Together, these arteries ensure that the muscle consistently receives the oxygen and nutrients needed for its function and endurance.
NEURAL INNERVATION
Moreover, the Longus Capitis is innervated by branches of the cervical spinal nerves (C1-C4). This innervation, in turn, provides the muscle with the ability to coordinate head and neck movements effectively, thereby contributing to smooth and controlled flexion.
TRIGGER POINT
Trigger points in the Longus Capitis can cause discomfort, as well as neck stiffness and headaches. Furthermore, pain may radiate from the neck to the occipital region, thereby leading to tension headaches or difficulty maintaining posture.
CONCENTRIC FUNCTION
During concentric contraction, the Longus Capitis flexes the head and neck, bringing the chin towards the chest. This movement is essential for looking down and stabilising the head during forward motions.
ECCENTRIC FUNCTION
The muscle assists in controlling the extension of the head and neck, gradually slowing down the return to a neutral position. Therefore, this eccentric function is vital in preventing abrupt or uncontrolled head movements.
ISOMETRIC FUNCTION
The Longus Capitis works isometrically to stabilise the head and neck when static, such as during prolonged sitting or activities requiring head stability. This function helps maintain cervical posture.

- Trapezius (upper fibres)

COMMON INJURIES
- Muscle Strain: Overuse or sudden movements can, therefore, lead to muscle strain, resulting in neck pain, stiffness, and limited motion.
- Tension Headaches: Trigger points or tightness in the Longus Capitis can cause radiating headaches, often linked to prolonged poor posture.
EXERCISES
- Chin Tucks: Pull the chin directly back to engage and strengthen the Longus Capitis. This exercise improves neck posture and reduces strain.
- Neck Flexion With Resistance: Apply light resistance with the hand while flexing the head forward to strengthen neck flexors, particularly the Longus Capitis.
- The Isometric Head Holds: Press the forehead against a static surface, holding for several seconds to build endurance in the deep neck muscles.
- Supine Head Lifts: Lying on your back, slightly lift the head off the ground to activate the Longus Capitis and increase muscle strength.
- Wall Angels: Stand with your back against the wall and move your arms up and down to activate the neck and upper back muscles.
STRETCHES
- Neck Flexion Stretch: Gently lower the chin to the chest, feeling a stretch along the back of the neck and relieving tension in the Longus Capitis.
- Lateral Neck Stretch: Tilt the head to one side, gently stretching the opposite side to release tightness in the neck muscles.
- Forward Head Bend: Sit or stand and slowly bend the head forward, elongating the posterior neck muscles and relieving stiffness.
- Diagonal Neck Stretch: Combine a gentle head tilt with rotation to stretch both the side and back of the neck, targeting multiple muscles.
- Neck Retraction Stretch: Sit or stand, retract the head by pulling it straight back to alleviate pressure on the cervical spine and lengthen the neck muscles.
