Answer 1

The spinal cord ends at different levels in children and adults, with L3 in children and L1-L2 in adults. The iliac crest is a landmark for identifying the level of the lumbar vertebrae.

Step-by-step explanation:

The spinal cord, specifically the conus medullaris and dural sac, ends at different levels between child and adult. In a child, the spinal cord ends around the level of the third lumbar vertebra (L3). In adults, the spinal cord typically ends around the level of the first or second lumbar vertebra (L1-L2). The iliac crest, which is a curved, superior margin of the ilium, can be used as a landmark for identifying the level of the lumbar vertebrae.
