The ant.2/3 of the tongue is associated with pharyngeal arch 1:
General sensation....> the lingual branch of CN V.
Tast sensation.....>chorda tympani of CN VII

The post.1/3 of the tongue is associated with pharyngeal arch 3:
General sensation and taste......> CN IX

Intrinsic and extrinsic muscles of the tongue are derived from myoblasts that migrate into the tongue region from occipital somites.....> motor innervation is supplied by CN XII.
