At which vertebral level does the spinal cord typically terminate in adults?

Show Answers

At the lower edge of the first lumbar vertebraAt the bottom of the third lumbar vertebraAt the lower boundary of the first sacral vertebraAt the base of the fifth lumbar vertebra

Explanation

In adults, the spinal cord usually ends at the lower border of the first lumbar vertebra (L1). This is a key anatomical landmark distinguishing the end of the spinal cord from the beginning of the cauda equina. Other vertebral levels listed, such as L3, S1, and L5, are lower than the typical termination point.
