The thyrohyoid muscle is a small
Structure
The thyrohyoid muscle is a small,[1] broad and short muscle.[2] It is quadrilateral in shape.[1] It may be considered a superior-ward continuation of sternothyroid muscle.[1]
It belongs to the infrahyoid muscles group and the outer laryngeal muscle group.[3]: 567–568
Attachments
Its superior attachment
Its inferior attachment: 538
Innervation
The thyrohyoid muscle is innervated (along with the
Blood supply
The muscle is provided with arterial blood by branches of the superior thyroid artery, and of the lingual artery.[1]
Relations
The thyrohyoid muscle forms the inferior boundary of the carotid triangle.[5] It is situated deep to (beneath) the (depending upon the source) superior portion of[2]/superior belly of[3]: 538 the sternohyoid muscle,[2][3]: 538 and the superior portion of[2] the omohyoid muscle.[2][3]: 538
Function
The thyrohyoid muscle depresses and fixates the hyoid bone. It elevates the larynx during swallowing.[3]: 538 By controlling the position and shape of the larynx, it aids in making sound.[6]
