- parapodia
- appendages that function in gas exchange and locomotion
- substance that leeches (class hirudinea) release; is an anesthetic and prevents coagulation of blood
- hirudin
- infolding of phylum annelida intestine
- typhosole
- (phylum annelida) consists of a bladder and coiled glandular loops
- nephridia
- these cells make up the outerost layer of the intestinal epithelium (annelida)
- chloragogen
- functions in temporary food storage in annelids
- crop
- what are the four living groups of arthropods?
-
cheliceriform
myriapod
crustacean
hexapoda - what is the extinct group of arthropods?
- trilobite
- functions of arthropod cuticle:
-
covering the body wall
inward folds form supporting braces (anchor internal structures and provide attachment sites) - (arthropod) specialized sensory organs that appear on the body surface. Microscopic hair like structures
- sensilia
- filter the hemolymph in arthropods from the body cavity and pass it into the midgut to mix with fecal wastes
- malpighian tubules
- (arthropoda) function as a gas exchange surface
- tracheoles
-
(arthropoda)
egg hatches in a nymph - incomplete or simple metamorphosis
- a smaller version of an adult bug
- nymph
- nymph and adult insects are wingless; major difference between two is size
- ametabolous
- insects where the nymphs are aquatic and gill breathing. Majorly different from adults
- hemimetablous insects
- examples of hemimetabolous insects
-
dragonflies
mayflies
stonefles -
Insects that are winged as adults
nymphs and adults feed on similar vegetation - paurometabolous insects
-
egg
larva
molts molts molts
pupa
adults
what kind of metamorphosis is this? - holometabolous (complete)

- class marine annelids with many setae
- polychaeta
- class of leeches
- hirudinea
- class of earthworms and freshwater worms
- oligochaeta
- where is the intestinal epithelium in annelids derived from
- the endoderm
- excretory organs that collect fluid and processes waste
- nephridium
- which are larger and wrap around the esophagus: the seminal vesicles or the seminal receptacles?
- seminal vesicles
- contain the testes (annelids)
- seminal vesicles
- receive sperm released by mate (annelids)
- seminal receptacles
- sensory device located above the mouth (earthworm)
- prostomium
- what are the three layers of the arthropod cuticle?
-
epicuticle
