The genioglossus muscle is a fan-shaped extrinsic muscle of the tongue which makes up the bulk of the tongue.
Summary
- origin: superior mental spine of the symphysis menti (posterior surface of midline mandible)
- insertion: entire tongue mass and body of the hyoid bone
- nerve supply: hypoglossal nerve
- blood supply: lingual artery and the submental branches of the facial artery, both from the ECA
- action: protracts and depresses the tongue
