Arthropods Vocabulary
Arthropods VocabularyGanglion – collection of nerve cells
Malpighian tubules – extract wastes from blood and adds them to feces that move through the gut.
Chelicerae – fangs on the spider used to stab and paralyze prey.
Arthropods VocabularyPedipalps (palps) – second pair of
appendages of arachnids (spiders) that are near the mouth used as sensory such as smell/taste and grab prey.
Arthropods VocabularyBook lungs – a type of
respiratory organ in spiders and scorpions; they are deep pockets on the lots of folds that are moist; blood passing through them picks up oxygen from the surrounding air.
Arthropods VocabularyTracheal tubes (tracheae) – tiny tubes that carry air
(oxygen) directly to cells in some land arthropods; respiratory gases are exchanged across these tubes by diffusion.
Spiracles – breathing holes located along the side of the body of terrestrial arthropods
Spinnerets – organs in spiders spin web on backside
Arthropods VocabularyCompound eye – 1 eye made of many smaller
visual units which can see in all directions.
Carapace – hard outer shell
Mandible – mouthpart adapted for biting and grinding food.
Arthropods VocabularyMaxillae - chewing jaws located behind the
mandibles
Maxillipeds – holds food
Arthropods VocabularyAntennae – a pair of sense organs located
near front of head.
Antennules – smaller pair of sense organs
Arthropods VocabularyCheliped – big claw in crustaceans
Swimmerets - used in movement and reproduction
Arthropods VocabularyTelson – last division of
the body and forms the tail.
Uropod – flat broad tail (lobster)
Arthropods VocabularyThorax – body part that lies just behind the head
and and houses most of the internal organs. Abdomen – last (3rd) body segment of an
arthropod’s bodes most of the internal organs.
Arthropods VocabularyCephalothorax – region formed by the fusion
of the head with the thorax.
