Pterygoid bone


  • Webster's Revised Unabridged Dictionary
    • Pterygoid bone (Anat) a bone which corresponds to the inner plate of the pterygoid process of the human skull, but which, in all vertebrates below mammals, is not connected with the posterior nares, but serves to connect the palatine bones with the point of suspension of the lower jaw.
