8ocelli
two simple eye spots o turbellarians
9sporocyst
what mirricidium develops into, large bag of tissue with balls of cells
10rediae
what sporocysts develop unto, have cercarie inside them
11cercaria
balls in rediae with a tail, leave snail behind to find next determinate host
12metacercaria
cercariae that attach to host and becomes a cyst
13proglottid
segment on tapeworm with male and female sex organs, produced by asexual budding at scolex of a tape worm, reproduce sexually
14scolex
attachment organ at end of tapeworm
15cysticercus
fluid-filled bladder formed by tapeworm larvae encysting on skelatal muscles
16phylum gastrotricha
lophotrochozoan phyla, define by having cilia on vental surface they used to glid around ("belly gliders"), free-living marine and freshwater species
17phylum rotifera
lophotrochozoan phyla, define by having cilia that looks like a wheel and is used to move around
18phylum acanthocephala
lophotrochozoan phyla, define by having a spiney head with proboscis used for attachment, endoparasites that require two hosts to complete life cycle
19phylum ectoprocta
lophotrochozoan phyla, define by living in sessile colonies of zooids, looks like moss, filter feeders
20phylum nemertea
lophotrochozoan phyla, round worms, define by having a long probosis and found in mud and sand
21phylum brachiopoda
lophotrochozoan phyla, define by having bivalve shell, shell is dorsal and ventral
22the correct sequence of development in a typical trematode is:
- egg, miracidium, redia, sporocyst, cercaria
- egg, miracidium, sporocyst, redia, cercaria
- egg, miracidium, cercaria, redia, sporocyst
- egg, miracidium, cercaria, sporocyst, redia
23The monogenean flukes
- are all ectoparasites
- are usually found in rabbits
- require both an indeterminate host and definitive host
- all of these
24structure found in tapeworms but not in other flatworms are
- proglottids
- mouth
- suckers
- all of these
25humans become inflected with liver flukes by
- eatinf infected fish
- being bitten by a mosquito
- swimming in contaminated water
- drinking contaminated water
26Pseudocoelomates are more advanced than Plathelminthes because they have
- an excretory system
- a complete digestive tract
- a nervous system
- a respiratory system
27elephantiasis is caused by filarial worms that live in the
- muscles
- lymphatic system
- intestine
- heart
28the system that is absent in nematodes is the
- excretory
- reproductive
- digestive
- circulatory
29acanthocephalans are
- called spiney-headed worms
- called horseworms
- are rare
- resemble lobsters
30common interminediate hosts for most trematodes are
31nematmorphs are
- called spiney-headed worms
- are free-living as adults and parasitic as juveniles
- are rare
- resemble rotifers
32ribbon worms (Nemerteans) are
- carnivores
- nearly all marine dwellers
- nonparasitic
- all of the above
33the excretory structures of flatworms are called __________
flame cells
34nematodes have a constant number of cells, called _________
eutely
35the hosts of thr juvenile stages of horsehair worms are varius terrestrial _________
36the structure that fastens as tapeworm to its host is called a _______
scolex
37rotifers have a unique ciliated crown called the __________
38a host that harbors the immature stage of a parasite is called the ______ host
indeterminate
39the structures that propel (locomote) gastrotrichs are __________
40members of the Phyla Brachiopoda and Ectoprocta feed using a structure called a ________
lophophore
41the outer body of Nematodes is called a ________, which is shed during a process called _________
cuticle, ecdysis
42which anatomical feature accounts for the side-to-side thrashing movement charecteristic of Nematodes
longitudinal muscles
43name 3 advantages of a pseudocoelom
1. hydrostatic skeleton for movement
2. less energy, nonliving cells
3. space for organs = diversification
44what is the host of the dog tapeworm
mosquitos
