A dicondylic skull has two articulatory condyles that connect the skull to the body. 

Cranial nerves are usually paired nerves that originate in the brain and the brainstem and emerge through apertures in the skull to extend throughout the body on both sides. They facilitate the functioning of the sense organs and muscles.

Members of class Amphibia have a dicondylic skull and ten pairs of cranial nerves.

Members of classes Reptilia and Aves (birds) have a monocondylic skull and twelve pairs of cranial nerves.

Members of class Mammalia have a dicondylic skull and twelve pairs of cranial nerves.
