Anatomy of the Sternothyroid Muscle

The sternothyroid is one of the small muscles in your neck that plays a role in the movement and support of your larynx (voice box). Here are the evidence-based details:

Structure & Location

• Location: The sternothyroid muscle is located in the front of the neck. It runs from the sternum (breastbone) up towards the thyroid cartilage (part of your voice box).

• Size: It is a thin, strap-like muscle that lies just beneath other neck structures.

Origin & Insertion

• Origin: The muscle originates from the back of the manubrium of the sternum (upper part of the breastbone).

• Insertion: It attaches to the side of the thyroid cartilage. This connection is important for its role in moving the larynx.

Blood Supply

• Arterial Supply: The muscle receives blood from branches of nearby arteries such as the inferior thyroid artery.

• Venous Drainage: Blood is drained through nearby venous channels that help carry away waste products.

Nerve Supply

• Innervation: The muscle is primarily supplied by motor nerves from the ansa cervicalis (a loop of nerves in the neck). This nerve control is essential for muscle movement and coordination.

Key Functions

1. Depressing the Larynx: Helps lower the larynx during swallowing.

2. Voice Modulation: Assists in adjusting the tension in the laryngeal framework, influencing voice quality.

3. Supporting Neck Structures: Works in coordination with other neck muscles to maintain posture.

4. Aiding in Breathing: Contributes to the overall mechanics of breathing by stabilizing the neck.

5. Swallowing Assistance: Facilitates smooth swallowing movements by positioning the larynx.

6. Head and Neck Movement: Plays a minor role in the overall movement and stability of the head and neck.

Understanding this basic anatomy is important for grasping how injuries to this muscle can affect your daily life.

Types of Sternothyroid Muscle Injury

Injuries to the sternothyroid muscle can occur in several ways. They are typically categorized into the following types:

• Strain: Overstretching or tearing of the muscle fibers.

• Contusion: Bruising from a direct blow or trauma.

• Partial Tear: Incomplete tear where only some muscle fibers are damaged.

• Complete Tear: A full rupture of the muscle.

• Overuse Injury: Repeated stress or strain from activities like heavy lifting or intense sports.

• Acute Injury: A sudden injury, often due to trauma or a fall.

• Chronic Injury: Long-term damage from ongoing repetitive stress.

Each type of injury may require different treatment approaches, so understanding your specific injury is key.
