Quizplus · Accepted Answer

The laminae of the posterior vertebral arch do not unite at the midline in individuals with spina bifida, a congenital defect where the neural tube fails to close properly during fetal development. Osteoporosis is a condition characterized by weakened bones due to loss of bone density. Rickets is a disease caused by a deficiency in vitamin D or calcium, resulting in softening and weakening of bones. Cleft palate is a birth defect where the roof of the mouth has a split or opening, and does not affect the vertebral arch.
