A

A fluid filled cavity between the alimentary canal and the body wall

31
Q

Acoelomate

A

No coelomic cavity exists

32
Q

Pseudocoelomate

A

A coelom exists but it is lined by mesoderm only on the body wall not around the gut

33
Q

Coelomate (eucoelmate or true coelom)

A

The coelom is lined both on the inside of the body wall and around the gut by the mesoderm. With true coelom also have mesunteries, which suspend the body organs within the coelom

34

Body symmetry

A

The body plan of an animal, how it’s body parts are arranged

35
Q

Asymmetry

No pattern

Corals and sponges

37
Q

Bilateral symmetry

A

Has right and left side (humans insects and cats)

38
Q

What happens to cephalization if animals are more complex

A

The more complex the animals become the more pronounced their cephalization

39

Toward the tail

41
Q

Dorsal

A

Back side
