Infrahyoid muscles are a group of four paired muscles in the front of your neck. They help lower the hyoid bone and larynx during swallowing and speaking. An injury to these muscles can cause pain, limit movement, and affect basic functions like swallowing.
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
-
Swallowing: Helps lower the hyoid bone during swallowing.
-
Speech: Assists in proper voice production.
-
Stabilizing the Neck: Supports the throat and neck during movement.
-
Laryngeal Movement: Facilitates the movement of the larynx during breathing.
-
Assisting Breathing: Plays a role in maintaining an open airway.
-
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.
