Question

Quizplus · Accepted Answer

Spina bifida is a congenital abnormality where there is incomplete closure of the vertebral arch, resulting in an open defect that allows the meninges and/or spinal cord to protrude through the opening. This can lead to neurological deficits and other complications. A herniated intervertebral disk is a separate condition where the soft tissue between two vertebrae protrudes outward, usually causing pain or discomfort. Meningioma and neuroblastoma are both types of tumors that can occur in the spinal column, but they do not result in an abnormal opening in the same way that spina bifida does.
