Five nonrib-bearing lumbar-type vertebrae refer to the five lumbar vertebrae in the lower back that do not have ribs attached to them, distinguishing them from thoracic vertebrae. These vertebrae are characterized by their larger size and more robust structure, providing support for the upper body and allowing for flexibility and movement. They play a crucial role in bearing weight and protecting the spinal cord while facilitating a range of motions, such as bending and twisting.

There are typically five lumbar vertebrae.
The lumbar vertebrae in the lower back is typically five in number and unfused.
Vertebrae are divided into sections: the atlas and axis account for the first cervical vertebrae, of which there are 7 in total; there are 12 thoracic vertebrae, 7 lumbar vertebrae, 1 sacrum (5 separate vertebrae in a baby), and 1 coccyx (4 separate vertebrae in a baby).

The lumbar vertebrae are the largest because they need to be able to support more weight.
The medical term for the five fused vertebrae above the tailbone is the sacrum.
The thoracic spine has the most vertebrae - twelve.
The five fused vertebrae with which the hip bones move are collectively known as the sacrum. The sacrum forms the posterior wall of the pelvis and connects the spine to the hip bones, providing stability and support for the body.
