  1. ARTHROPODA VOCAB • 1.Malpighian tubules - excretory and osmoregulatorytubules • 2.Preadaptation-a new structure or process that enhances reproductive ability when an individual encounters new environmental situations • 3. Compound eyes -many individual lenses in one eye • 4. Tagmata-actual body regions that are specialized for feeding, sensing, moving & visceral functions

  2. 5. Book lungs-exoskeleton is modified into plates that resemble pages of a book; found in spiders • 6. Cephalothorax-fused head and thoracic region of some crustaceans and some arachnids • 7. Hemocoel-large tissue space that contains blood • 8. Pedipalps-2ndpair of appendages in chelicerate arthropods; fx in sensory • 9.Tagmatization -regional specialization

  3. 10. Exoskeleton- skeleton outside the body • 11. Maxillae- 4thand 5th appendages for handling food • 12. Mandibles-paired grinding, tearing mouthparts, derived from anterior headappendages • 13. Sensilla- modifications in the arthropod’s skeleton that form sensory structures • 14. Chelicerae- one of two pairs of anterior appendages on arachnids; may be pincerlike or modified for piercing and sucking
