Q

What is rostral/caudal

A

head/tail

17
Q

Why are neurulation defects so common

A

because there are 5 independent neural tube closing events meaning that there is a high chance that something could go wrong

18
Q

What happens if neurulation closing event 1 doesnt happen properly

A

craniorachishisis

19
Q

what happens if neurulation closing event 2 doesnt happen properly

A

anencephaly

20
Q

what happens if neurulation closing event 5 doesnt happen properly

A

spina bifida
