hierarchical_section_title: Thyrohyoid muscle
context_page_description: The thyrohyoid muscle is a small skeletal muscle on the neck which depresses the hyoid and elevates the larynx.
  This quadrilateral muscle appearing like an upward continuation of the sternothyreoideus. It belongs to the infrahyoid muscles group.
  It arises from the oblique line on the lamina of the thyroid cartilage, and is inserted into the lower border of the greater cornu of the hyoid bone.
  It is innervated by thyrohyoid branch of C1 nerve. This nerve branches from the first cervical nerve as it joins the hypoglossal nerve for a short distance. This is the only exception in the infrahyoid muscles, or strap muscles, that is not innervated by ansa cervicalis.
