What differentiates lumbar vertebrae from cervical vertebrae?
Understand the Problem
The question is asking for the key differences between lumbar and cervical vertebrae, particularly their structural characteristics.
Answer
Lumbar vertebrae are larger for weight support; cervical vertebrae are smaller for head movement.
Lumbar vertebrae are larger than cervical vertebrae as they must support the upper body weight. Cervical vertebrae are smaller, support head movement, and have unique bifid spinous processes.
Answer for screen readers
Lumbar vertebrae are larger than cervical vertebrae as they must support the upper body weight. Cervical vertebrae are smaller, support head movement, and have unique bifid spinous processes.
More Information
Lumbar vertebrae support more weight and are less flexible compared to cervical vertebrae, which allow more movement due to their smaller size and anatomy.
Tips
Confusing the size and location of the vertebrae is common. Remember that lumbar vertebrae are in the lower back and support more weight, while cervical ones are in the neck facilitating head movement.
