  • All beaks are composed of two jaws, generally known as the upper mandible (or maxilla) and lower mandible (or mandible). (wikipedia.org)
  • The upper, and in some cases the lower, mandibles are strengthened internally by a complex three-dimensional network of bony spicules (or trabeculae) seated in soft connective tissue and surrounded by the hard outer layers of the beak. (wikipedia.org)
