Infrahyoid Muscle Injuries

Anatomy? of the Infrahyoid Muscles

Understanding the structure of the infrahyoid muscles is key to knowing how injuries occur and how they are treated.

Structure & Location

There are four main infrahyoid muscles:

• Sternohyoid: Runs from the sternum? (breastbone?) upward to the hyoid bone.

• Omohyoid: Has two bellies (upper and lower) connected by a tendon?; starts at the shoulder blade? and inserts into the hyoid bone.

• Sternothyroid: Runs from the sternum to the thyroid? cartilage? of the larynx.

• Thyrohyoid: Runs between the thyroid cartilage and the hyoid bone.

These muscles are located in the anterior (front) part of the neck, below the hyoid bone.

Origin & Insertion

• Origin: The starting points of these muscles are found on the bones of the neck and chest (for example, the sternum or scapula?).

• Insertion: They attach to the hyoid bone or nearby structures like the thyroid cartilage.

Blood Supply

• Arterial Supply: Branches from the superior thyroid artery? and other small arteries? in the neck provide blood.

• Venous Drainage: Blood is drained by nearby veins? that lead back to the heart.

Nerve Supply

• Innervation: The muscles receive signals from the ansa cervicalis, a loop of nerves in the neck that controls many neck muscles.

Main Functions

1. Swallowing: Helps lower the hyoid bone during swallowing.

2. Speech: Assists in proper voice production.

3. Stabilizing the Neck: Supports the throat? and neck during movement.

4. Laryngeal Movement: Facilitates the movement of the larynx during breathing.

5. Assisting Breathing: Plays a role in maintaining an open airway.

6. Facilitating Mastication: Helps position the hyoid bone for chewing.

Types of Infrahyoid Muscle Injuries

Injuries can vary in severity and mechanism. Common types include:

• Strains: Overstretching or tearing of muscle fibers.

• Contusions: Bruising? due to a direct blow.

• Partial Tears: Incomplete muscle fiber disruption.

• Complete Tears: Full separation of the muscle fibers (rare).

• Overuse Injuries: Repetitive strain? from excessive use.

• Traumatic Injuries: Caused by accidents or falls.

Causes of Infrahyoid Muscle Injuries

1. Trauma? from Car Accidents: Sudden impact can strain neck muscles.

2. Sports Injuries: Contact sports or falls can lead to strains.
