What embryological processes fail if a baby is born with an omphalocele
Midgut failed to return to abdominal cavity after physiological herniation
The important adult structure which is derived from the remnants of the notochord
Nucleus pulposus of the intervertebral disc
If lower end of neural tube does not close properly, causes spina bifida -> spinal cord does not develop properly
Describe formation of gastrointestinal tract
Week 3 - epiblast move through primitive streak and replace hypoblast, forms definitive endoderm. Endoderm becomes lining of gut tube -> later becomes gastrointestinal tract
The lateral plate mesoderm is...

Metencephalon develops into the...
Pons, cerebellum
Difference between omphalocele and gastroschisis
Omphalocele covered in membrane sac, organs completely exposed in gastroschisis
