  10. Slide 10 - Gastulation

  11. Slide 11 – Blastopore and Archenteron

  12. Slide 12 - Neurulation

  13. Slide 13 – Radial and spiral cleavage

  14. Slide 14 – Cleavage patterns

  15. Slide 15 – Protostome and deuterostome body plan

  16. Slide 16 – Protosomes - schizocoelom The blastopore is the single opening of the archenteron and in protosomes, the blastopore forms the mouth. The development of the mesoderm in protosomes are called schizocoelom which is defined as the developing mesoderm rises from the area near the blastophore where division takes place forming the mesoderm

  17. Slide 17 – Deuterostomes - enterocoelom In deuterosomes, the blastopore (single opening of the archenteron) forms the anus. The development of the mesoderm is called an enterocoelom which is defined as the developing mesoderm rises from a pair of mesodermal pouch from the primitive gut (endoderm). This pouch enlarges until they meet and fuse
