OMOHYOID

• Origin

 
Inferior belly: superior border of the scapula near the suprascapular notch

 
Superior belly: intermediate tendon (connected to the inferior belly by a fascial sling anchored to the clavicle and first rib)

• Insertion

 
Inferior belly: intermediate tendon
Superior belly: lower border of the body of the hyoid bone

• Agonist(s)

- Sternohyoid,

- Thyrohyoid,

- Sternothyroid
(These muscles assist in depression of the hyoid bone)

• Antagonist(s)

- Digastric,

- Mylohyoid,

- Stylohyoid
(These elevate the hyoid bone during swallowing and speech)

• Function

 
Depresses and stabilizes the hyoid bone during swallowing and speech.

Helps maintain tension in the cervical fascia and supports vascular and airway structures by anchoring the hyoid.

TRIGGER POINT(S)

• Location

 
Trigger points are usually located along the path of the inferior and superior bellies, particularly near the intermediate tendon (just above the clavicle) and where the superior belly approaches the hyoid.

Palpation may be challenging due to the muscle's thin, strap-like nature and depth.

• Pain Referral Pattern

 
Pain is typically referred to the lateral neck, just above the clavicle, and may extend to the throat or radiate inferiorly along the front of the neck.

Clients may also report a tight or constricted sensation in the anterior cervical region or discomfort during swallowing.

💢

Potential Causes

 
• Repetitive neck flexion or poor head posture (e.g., forward head posture).

• Chronic coughing or throat clearing.

• Vocal strain or excessive speaking/singing.

• Emotional tension or stress affecting anterior neck muscles.

• Whiplash injuries or surgical trauma to the neck.

✅

 Prevention Tips

 
• Maintain upright posture, especially during prolonged desk work or mobile device use.

• Incorporate neck mobility and postural correction exercises.

• Use proper vocal technique and avoid vocal strain.

• Address and manage stress-related muscular tension in the neck.

• Seek professional care for persistent anterior neck discomfort or dysfunction.
