Sections:
The muscles of the tongue are divided into 2 groups each comprising 4 muscles. They are classified as intrinsic (to the tongue) and extrinsic muscles. They allow for the complex movements of the tongue and are all innervated by the hypoglossal nerve (CN XII) except one:
- intrinsic muscles of the tongue which do not have attachments outside the tongue and who's action is to alter the shape of the tongue:
-
extrinsic muscles of the tongue (mnemonic) which have attachments outside the tongue and therefore their actions alter the position of the tongue:
- genioglossus muscle: the majority of the tongue
- hyoglossus muscle
- styloglossus muscle
- palatoglossus muscle: supplied by the vagus nerve (CN X) via the pharyngeal plexus
