Which muscle pulls down the hyoid bone and has its origin at the manubrium and clavicle?

The muscle responsible for pulling down the hyoid bone that originates at the manubrium of the sternum and the clavicle is the sternohyoid. This muscle plays a key role in the positioning of the hyoid bone, which is important for various functions, including swallowing and speech production.

The sternohyoid inserts into the body of the hyoid bone and assists in lowering the hyoid after it has been elevated during swallowing. The connection to the manubrium and clavicle provides a stable anchor point that facilitates this action. Understanding the functions and attachments of the sternohyoid is crucial for comprehending how the muscular structures of the neck contribute to the dynamics of speech and swallowing.

Recognizing the specific origins and insertions of these muscles highlights their unique roles in the muscular system of the neck and their contributions to overall anatomical function.
