1-4 Exam Questions And Answers
correct answer ✅• Spina bifida (failure of POSTERIOR neuropore
to close)
• Anencephaly (failure of the ANTERIOR neuropore to close)
STAGE 1: Embryological Development -
correct answer ✅Neurulation
Nerves (PNS) -
correct answer ✅-fibers of sensory and motor neurons
(somatic/autonomic)
Anencephaly -
correct answer ✅defect in closure of the cephalic portion of the
neural tube that results in incomplete development of the brain
