Latin Copula linguae

Anatomical terminology

The copula linguae forms from the second pharyngeal arch and becomes covered by the hypopharyngeal eminence which forms from the third and fourth pharyngeal arches.[1]

The furcula is at first separated from the tuberculum impar by a depression, but later by a ridge, the copula, formed by the forward growth and fusion of the ventral ends of the second, third, and part of the fourth branchial arches.
