Term information






function notes

main functions are altering the tongue's position allowing for protrusion, retraction, and side-to-side movement

homology notes

The lamprey head contains another group of muscles, the epi- and hypo-branchial muscles (EBM and HBM), derivatives of anterior trunk myotomes. (...) The origin and the migration pattern of HBM precursors are very similar to that of the gnathostome MPP, especially to that of the tongue muscle precursors. Other evidence of homology of lamprey HBM to the gnathostome tongue muscle is that HBM is innervated by the nerve termed the hypoglossal nerve based on its morphological position associated with the head/trunk interface. (...) The HBM-specific expression of the LampPax3/7 gene is consistent with the homology of this muscle to the gnathostome tongue muscle, or to the hypobranchial series as a whole (including the infrahyoid and possibly the diaphragm in mammals).[well established][VHOG]



structure notes

All intrinsic and extrinsic muscles of the tongue are supplied by the hypoglossal nerve (CN XII), except for one of the extrinsic muscles, palatoglossus, which is innervated by the Vagus nerve CN X of the pharyngeal plexus.
