Question

1. what makes the lumbar vertebrae different from the cervical vertebrae and the thoracic vertebrae?the lumbar vertebrae are made up of seven bones.the lumbar vertebrae only allow flexion and extension movements.the lumbar vertebrae allow the twist and turn.the lumbar vertebrae are located in the middle of the back.

Explanation:

The cervical vertebrae (7 bones) are in the neck and allow a wide range of movements including rotation (twist and turn). The thoracic vertebrae (12 bones) are in the upper back and also allow some rotation. The lumbar vertebrae (5 bones) are in the lower back. Their structure and the way they articulate mainly allow flexion (bending forward) and extension (bending backward) movements. The statement "The lumbar vertebrae are made up of seven bones" is incorrect as there are 5 lumbar vertebrae. "The lumbar vertebrae allow the twist and turn" is wrong as that's more characteristic of cervical and some thoracic vertebrae. "The lumbar vertebrae are located in the middle of the back" is incorrect as they are in the lower back.

Answer:

The lumbar vertebrae only allow flexion and extension movements.
