Location: Between bones Function: Cushions surfaces of joints |
|
|
Apopyles Osmium Mesohyl |
A: large opening leading to spongeocoel O: Surface pores that water enters through M: Semi-fluid matrix within sponge |
|
|
Blastula Stage |
Migration of blastomere to the periphery of the cell; creating a blastocoel |
|
|
Yolk Plug |
Marks the opening of the blastopore |
|
|
Vegetal vs. Animal Poles |
Vegetal: Yolk Animal: Embryo |
|
|
Gastrula Stage |
Autoinvagination (inward folding) into the blastocoel creating an inner cavity; the archenteron |
|
|
Deuterostome |
First opening is anus, then the mouth EX: explains why humans are shittalkers (joke) |

|
|
Discoidal Cleavage |
Cleavage planes are at one end of the cell |
|
|
Fertilization Membrane |
Membrane that forms around the egg to prevent further polyspermy EX: Slow block and fast block |
