external definition
Azygous, dermal bone of intramembranous origin that underlies the ventral surface of the braincase in anurans and salamanders. In caecilians, the parasphenoid and other bones are fused to form the Os basale.[AAO], Dermal bone that forms part of the base of the skull and the lateral walls of the braincase through its ascending processes. It may articulate with the vomer anteriorly, the prootics and exoccipitals laterally, and the basioccipital posteriorly. The parasphenoid is an elongate median bone.[TAO]
