Describe how spina bifida occurs and its impact on fetal development.
What will be an ideal response?
Ans: During the first twenty-eight days of pregnancy, special embryo cells from a closed tube that will become the brain and spinal cord. When this process is interrupted and the tube does not completely close, a congenital abnormality known as a neural tube defect occurs. When it occurs in the area of the spinal cord, a condition known as spina bifida occurs. In the most severe form, myelomeningocele spina bifida occurs, the baby is born with a sac on it back and the spinal cord pouches out into the sac. The spinal cord does not properly function at the point of the sac and below. Surgery will be performed to remove the sac when the infant is born, but the damage to the spinal cord cannot be reversed.
The characteristics of myelomeningocele spina bifida depend on the location of the defect. As with a spinal cord injury, there will be a lack of movement and sensation below the area of injury. Although the defect can occur anywhere along the spinal column, it typically occurs in the lower part of the spinal cord.
