Sections:
The hyoglossus muscle is a thin, quadrilaterally shaped muscle in the upper neck and the floor of the mouth. It is one of the extrinsic muscles of the tongue. The submandibular ganglion suspended from the lingual nerve sits on it.
Summary
- origin: hyoid bone: from the entire length of the greater cornu and front of the body of the hyoid
- insertion: side of the tongue between styloglossus laterally and the inferior longitudinal muscle medially
- blood supply: sublingual branch of the lingual artery and the submental branch of the facial artery
- innervation: hypoglossal nerve
- action: depresses and retracts the tongue
