SEMISPINALIS CAPITIS

• Origin

 

Transverse processes of C4-T6 vertebrae

 

• Insertion

 

Occipital bone between nuchal lines and mastoid process

 

• Agonist(s)

 

- Erector spinae

 

• Antagonist(s)

 

- Sternocleidomastoid

 

• Function

 

Extends and rotates head, assists in head and neck posture

 

TRIGGER POINT(S)

 

 

• Location

 

Trigger points are typically located in the muscle belly, deep in the posterior neck.

 Prolonged periods of looking up or down, such as during computer or phone use.

 

 Stress and tension, especially in the neck and upper back muscles.

 

 Trauma or injury to the head or neck.

 

 

• Prevention Tips

 

 Maintain proper posture, especially keeping the head aligned over the shoulders.

 

 Incorporate regular stretching and strengthening exercises for the neck and upper back muscles.

 

 Take breaks and adjust ergonomics during activities involving prolonged neck extension or rotation.

 

 Manage stress through relaxation techniques and regular physical activity.

 

 Avoid prolonged periods of looking up or down, and maintain a neutral head position.
