Cnidaria; forms from zygote so zygote can move

13
Q

Umbo

A

Bivalves; oldest part of the shell

14
Q

Radula

A

Mollusca (except bivalves); “tongue” that scrapes material, acts as conveyor belt to move food towards stomache

15
Q

Siphons

Bivalves; extension of the mantle, draws water in or pushes it out

16
Q

Nephridial tubules

A

Bivalves; kidneys

17
Q

Free-swimming trochophore larva

A

Bivales, annelids; larve stage after egg hatches

18
Q

Glochidia stage

A

Freshwater bivalves; specialized veliger stage. After internal fertilization, attaches to fish gills and lives as parasite

19
Q

Nauplius

A

Most common crustacean larvae

20
Q

Green gland

A

Part of crustacean excretory system, utilizes hydrostatic pressure

21
Q

Malpighian tubules

A

Used in insect excretory system

22
Q

Hemolymphs

A

Involved in crustacean respiration

23
Q

Tracheal system

A

System of tube involved in insect respiration

24
Q

Podia

A

Enchinodermata, tube feet

25
Q

Ampulla

A

Enchinodermata - muscle sack that hold fluid above the podium, creates a “suction cup”

26
Q

Ossicles

A

Plates on the calcerous endoskeleton of echinoderms

27
Q

Catch collagen

A

Asteroidea - specialized connective tissue. Can be controlled by nervous system to change from “liquid” to “solid”

28
Q

Pedicellarie

A

Pincer-like jaws controlled by muscles, keep body surface free of debris

29
Q

Papulae

A

Asteroidea - small projects of coelomic cavity that extend through ossicles. Aids in gas exchange

30
Q

Notochord

A

Chorodates, flexible but stiff tissue, becomes vertebrae in most vertebrates

31
Q

Dorsal Nerve Cord

A

Chordates - anterior ends enlarges to from brain. In vertebrates brain protected in bone/cartilage cranium

32
Q

Pharyngeal pouches and slits

A

Chordates - slits lead from pharyngeal cavity to outside. In fish - makes up internal gills. In humans - make-up part of the middle ear, ear drum, tonsils, etc.

33
Q

Endostyle or thyroid gland

A

Chordata - endostyle secretes proteins, thyroid secretes hormones

34
Q

Postanal Tail

37
Q

Archeocyte

A

Aids in porifera digestion, embeded in mesohyle

38
Q

Pinacocytes

A

Aids in porifera protect, embeded in mesohyle
