26. 
Two basic kinds of body organization are found among the panarthropods
 
1) in the Onychophorans, Myriapods, Insects and Crustaceans the body is divided into an anterior tagma, the head, which consists of fused anterior segments, and the remainder of the body is the trunk.
2) In the Arachnids the most anterior tagma is the prosoma, which also consists of fused anterior segments. Although the prosoma is functionally comparable to the crustacean cephalothorax, the two body regions are not homologous because different segments make them up. The hind part of the arachnid is called the opisthosoma and is again functionally analogous but not homologous to the abdomen of other arthropods.
 
27. 
insects it is divided into three tagma
 
the prothorax, mesothorax, and metathorax.
 
28. 
carapace
 
1) fused with the thoracic segments to form a cephalothorax as in the decapods
2) carapace is generally a diagnostic feature of the Crustacea, it is absent in copepods, isopods, amphipods, and anostracans
 
29. 
two major types of mouthparts in the arthropods
 
Chelicera are a pair of pre-oral appendages that are either chelate (ie. horseshoe crabs) or sub-chelate (i.e. spiders) and generally used for the capture of prey and/or the manipulation of food prior to entering the mouth
Mandibles: are massive and denticulate (bearing teeth) and used for tearing, crushing or grinding of food.
 
30. 
Pedipalps
 
1)are the second air of appendages on the prosoma of chelicerates.
2)They may be massive and chelate as in the scorpions or very leg-like as in the spiders.
3) used in both prey capture and manipulation and preparation of food for ingestion. They are also sensory in function
 
31. 
Antennae
 
anterior appendages on the head of mandibulates. There may be one or two pairs of antennae and the number is diagnostic as only crustaceans have two pair. Antennae are entirely sensory in function and usually multi-segmented or flagellar (whip-like) in structure
 
32. 
Arachnida two distinct body divisions
 
1) opisthosoma: lacks appendages
2) prosoma (central trunk) possesses six pairs (4pairs of walking legs, a pair of pedipalps or palps, and a pair of chelicerae), all of which become variously modified in the several orders of the class.
 
33. 
What appendages on crustaceans are analogous to pedipalps of Chelicerates?
 
first and second maxillae of the head located just posterior to the mandibles and extending forward to cover them, and up to the first three pairs of thoracic appendages, the maxillipeds
 
34. 
diagnostic characters of the Crustace/ mandibilates
 
three tagma, the head, thorax, and abdomen, and one or two pairs of antennae.
 
35. 
diagnostic characters of the chelicerates
 
two tagma; prosoma and opisthosoma and no antennae
 
36. 
the appendages of an adult crayfish may be classified as:
 

(1) foliaceous, characterized by the 2nd maxillae, (2) biramous as indicated by the swimmerets (pleopods)

(3) uniramous, an example of which is the walking leg.
