What is the medical term for congenital defect of spinal column resulting in pouching membranes?

The medical term for the congenital defect of the spine resulting in pouching membranes is meningomyelocele. This condition is a neural tube defect that occurs when the neural tube, which is the precursor to the brain and spinal cord, does not close properly during fetal development. As a result, a portion of the spinal cord and its meninges (the protective layers surrounding the brain and spinal cord) protrude through an opening in the back, forming a sac-like protrusion. Meningomyelocele can cause a range of neurological problems, including paralysis, incontinence, and intellectual disabilities, depending on the location and severity of the defect.
