GENERAL INFORMATION
The Longissimus Capitis is a vital component of the erector spinae muscle group, primarily involved in extending, bending, and rotating the head and neck. Longissimus capitis extends vertically up the back of the neck, connecting the thoracic spine to the skull, and is key for maintaining posture and stabilising the head. Its actions are crucial for everyday movements such as turning the head or looking upward. Overuse or poor posture can lead to tension in the longissimus capitis, making it a common source of neck pain and stiffness, emphasising the importance of its care in neck health regimes.
ORIGIN
The Longissimus Capitis originates from the transverse processes of upper thoracic and lower cervical vertebrae (T1-T5, C4-C7). This broad base provides the muscle with substantial leverage for head movements.
INSERTION POINT
Longissimus capitis inserts into the mastoid process of the temporal bone just behind the ear. This location is ideal for facilitating head movements relative to the neck.
MAJOR ARTERIES
The blood supply to the Longissimus Capitis is secured via the occipital artery and branches of the vertebral artery, ensuring it receives ample nutrients and oxygen.
NEURAL INNERVATION
Neural innervation is provided by the dorsal rami of the cervical spinal nerves, allowing for precise control over the muscle’s extensive range of motion.
TRIGGER POINT
Trigger points in the Longissimus Capitis can lead to radiating pain up the back of the neck and into the scalp, often contributing to tension headaches and upper neck discomfort.
CONCENTRIC FUNCTION
Concentrically, the Longissimus Capitis extends the head and neck backward and assists in lateral flexion and rotation to the same side, facilitating movements such as looking over the shoulder.
ECCENTRIC FUNCTION
Eccentrically, it controls the movement as the head and neck return to a neutral position, ensuring smooth motion and helping to prevent muscle strain.
ISOMETRIC FUNCTION
Isometrically, Longissimus capitis stabilises the head and neck, especially when holding the head in a fixed position for extended periods, critical during activities like driving.
RELATED MUSCLE-SCIENTIFIC NAMES
- Splenius Capitis
- Semispinalis Capitis
- Sternocleidomastoid
ANTAGONIST
- Sternocleidomastoid (during opposite side rotation)
- Scalene muscles (during lateral flexion to the opposite side)
COMMON INJURIES
- Muscle Strain: Often occurs from sudden movements or chronic poor posture, leading to neck stiffness and pain.
- Postural Neck Pain: Common in individuals who spend long hours in front of computers, causing ongoing discomfort and reduced mobility.
EXERCISES FOR LONGISSIMUS CAPITIS
- Neck Extensions: Lie face down and lift the head off the ground to strengthen the posterior neck muscles.
- Isometric Head Holds: Press the back of the head against a resistance band or wall without moving to build endurance.
- Dumbbell Shrugs: Elevate the shoulders to engage and strengthen the upper back and neck muscles.
- Resistance Band Pull-Downs: Perform pull-downs using a resistance band to engage and strengthen the upper back and neck.
- Yoga Poses For Neck Strength: Incorporate poses that involve extending and rotating the neck to improve flexibility and muscle tone.
STRETCHES
- Neck Flexion Stretch: Gently tuck the chin to the chest, stretching the posterior neck muscles.
- Upper Trapezius Stretch: Tilt the head to the side and slightly rotate to target the upper back and lateral neck.
- Foam Rolling: Use a foam roller along the upper back to release tension in the neck and shoulders.
- Dynamic Neck Rotations: Slowly rotate the neck in a controlled manner to improve range of motion and flexibility.
- Lateral Neck Stretch: Lean the head towards each shoulder, holding the stretch to alleviate tightness in the neck.
