the three embryonic cell layers

Back 22

ectoderm

endoderm

Front 23

the major distinction between protostomes & deuterostomes

Back 23

their embryonic development distinguishes these two

Front 24

protostomes

Back 24

the opening of the blastopore is the mouth

Front 25

deuterostomes

Back 25

opening of the blastopore is the anus

Front 26

animal body plan

Back 26

the basic structural design of an animal

Front 27

asymmetry (animal)

Back 27

no plane of symmetry

Front 28

radial symmetry (animal)

Back 28

when any plane crossing the central axis can divide the animal into two similar parts

Front 29

bilateral symmetry

Back 29

only one plane can cut into the animal and make two roughly similar mirror images

Front 30

body cavity

Back 30

fluid-filled space that lies between cell layers within the body of many animals

Front 31

ceolom

Back 31

a body cavity lined by mesodermal (middle layer) layers

Front 32

most animals can be grouped into three major categories based on the presence and structure of body cavity

Back 32

1. Acoelomates

2. Pseudocoelomates

3. Coelomates

Front 33

Acoelomates

Back 33

3 cell layers

Purpose of nervous system

Back 34

1. Coordinate movements

Back 41

This organism is a coelomate

Front 42

Hydrostatic skeleton

Back 42

A skeleton formed by a fluid filled compartment within the body (the coelom)

Front 43

Functions of body segmentation

Back 43

1. Improves movement control

2. Allows to alter the shape in complex ways

3. Facilitates specialization of different body regions

Front 44

Functions of external appendages

Back 44

1. Obtain food

2. Avoid predators

3. Enhance locomotion
