Some New Words
Annulus(i) the rings seen on the surface of some organisms such as leeches or
earthworms
Auricle an ear-like flap that is involved in chemical detection and not sound reception
Bivalve organisms that have two connected halves to the shell such as clams, each
half is called a valve
Cephalic having a head
Cnidocyte a specialized cell found in cnidarians that is used in feeding and protection
Medusa one of two body forms of cnidarians (jellyfish form)
Nerve net a net-like formation of nerves that both conduct and
Polyp one of two body forms of cnidarians
Definitive host organism in which the parasite passes through sexual development, site of
sexual reproduction
Dioecious having separate males and females
Eumetazoa animals that developed true tissues
Eyesot a light sensing structure that lacks a lens so not thought to form an
image
Gastrovascular cavity a central cavity in which digestion occurs, it has a mouth only and no
anus
Hydrostatic skeleton a fluid filled compartment upon which muscles contact and produce
movement in animals
Intermediate host organism in which the parasite passes through the asexual stage of
development, site of asexual reproduction
Mantle a sheet of epithelial tissue that covers the visceral mass (internal
organs) in mollusks
Monoecious having both male and female reproductive structures on the same
organism
Platyhelminthes phylum containing the flat worms
Parazoa animals that did not develop true tissues – sponges
Poriferans phylum containing the sponges
Amoeboid cell gives rise to all cells and the skeleton of a sponge, also transport food
Choanocyte a flagellated “feeding cell” found in sponges, also called collar cell
Osculum opening by which water flows out from the central cavity
(spongocoel) of a sponge
Mesohyl gelatin-like layer between the two surfaces of a sponge
Spicule a supporting skeletal spike in sponges (may be protein, silica, or
calcium carbonate)
Spongocoel a centrally located cavity in a sponge (not involved in digestion)
Proglottid individual body segment of cestodes, tapeworms
Protonephridia one of several types of structures that function in osmoregulation, it
has flame cells with cilia on the internal end where the fluid is
collected from the interstitium
Radula a belt of teeth (chiton) in the mouth of some mollusks, used to scrape
the substrate or make a hole in a shell
Scolex the anterior end of a cestode (tapeworm) on which the holdfast
structures (attachment structures) used to attach to the host’s intestine
are located
Septum(a) a dividing “wall” such as the tissue dividing the individual segments
of an earthworm
lOMoARcPSD|5735817
Seta(e) a stiff hair-like structure, bristle, it can be found on the outside of the
individual segments of an earthworm
Syncytium (syncytial epidermis) a multinucleated cell arising from the fusion of individual cells
or the specialize connection via gap junctions as seen in the
heart muscle for example
Visceral mass internal organs
