Term
Cephalization
Definition
a development of a head
Term
ectoderm
Definition
germ layer covering the embryo's surface
Term
endoderm
Definition
the innermost germ layer and lines the developing digestive tube, called Archenteron
Term
mesoderm
Definition
middle layer, develops in notochord
Term
coelom
Definition
true body cavity and is derived from mesoderm
Term
coelomates
Definition
animals that possess a true coelom
Term
pseudocoelom
Definition
is a body cavity derive from the mesoderm and endoderm
Term
pseudocoelomates
Definition
triploblastic animals that possess a pseudocoelom
Term
Acoelomates
Definition
triploblastic animals that lack a body cavity
Term
Two types of development
Definition
Protostome & Deuterostome
Term
Protostome Cleavage
Definition
spiral & determinate
Term
Deuterostome Cleavage
Definition

Radial & indeterminent 

-indeterminents:make it possible to have identical twins and stem cells.

 

Term
Protostome Development
Definition
the splitting of solid masses of mesoderm forms the coelom
Term
Deuterostome Development
Definition
the mesoderm buds from the wall of the archenteron(inner pouch of gastrula) to form the coelom
Term
Blastopore
Definition
forms during gastrulation and connects the archenteron to the exterior of the grastula
Term
Blastospore Protostome Development
Definition

Blastospore forms in the mouth

 

**prostitutes give it by mouth*

Term
Blastospore Deuterostome Development
Definition

Blastospore becomes the anus

 

**you DEU-DEU from anus*
