Spiral cleavageDeterminateFate of Blastopore MouthSchizocoely- coelem from splitting of mesoderm

Radial cleavageIndeterminateFate of Blastopore AnusEntercoely- mesoderm from outpocketing of archenteron formation of coelom

Meroblastic-partial cleavage (big eggs)Holoblastic- complete cleavage (small eggs)

ovum would be true if this is a ratovary at the time of ovulation...

Antrum

granulosa cells , secreteestrogen and progesterone post ovulation

arrow a little off!!!

fast block (Depolarization Na+ influx) , slow block (cortical reaction)No Polyspermy because:

with yolk plug

with neural tubeanterior is where?left side is where?

How would you tell a blastula from a morula?

neurulaovum Gastrulablastula8 cell morula

How would you tell a blastula from a morula? Blastula is hollow inside because of the blastocoel and there are more and smaller cells in a blastula

Zygote 4 cell morula blastula

archenteron

enterocoelous development:mesodermal cells near theroof of archenteron give rise to the coelom
