The five vertebrae that are fused within the pelvic bones are the sacral vertebrae, as well as a few vestigal caudal vertebrae that are called the coccyx in humans.
There are 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, the 5 sacral vertebrae fused to form the sacrum, and the 4 coccygeal vertebrae fused to form the coccyx. Depending on the way you count the number of bones, it comes to as few as 26 bones (just the fused sacrum and fused coccyx are counted) or 33 bones (if you count each bone that is fused).
The spine is composed of 33 movable segments called vertebrae. These vertebrae are divided into five regions: cervical (7 vertebrae), thoracic (12 vertebrae), lumbar (5 vertebrae), sacrum (5 fused vertebrae), and coccyx (4 fused vertebrae).
No, there are not 6 bones in the human spine. There are actually 33 vertebrae in 5 regions. These regions include: cervical (7 bones), thoracic (12 bones), lumbar (5 bones), sacral (5 fused bones), and coccygeal (4 fused bones).
The two sections of the spine that consist of fused bones are the sacrum, which is formed by the fusion of five sacral vertebrae, and the coccyx, which is formed by the fusion of four coccygeal vertebrae.
The last 4 fused vertebrae in the spine are called the sacrum. The sacrum is a triangular bone located below the lumbar vertebrae and is formed by the fusion of five sacral vertebrae.

The five bones fused in the lower back are called the sacrum. The sacrum is a triangular bone located between the two hip bones and forms the back part of the pelvis. It is made up of five separate vertebrae that fuse together during development.
The vertebral column usually consists of 33 vertebrae: 24presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae).

The human spine is made up of 33 vertebrae, which are the bones connected to it. These vertebrae are divided into five regions: cervical (7), thoracic (12), lumbar (5), sacral (5 fused), and coccygeal (4 fused). The sacral and coccygeal vertebrae are fused into single structures, so there are 24 individual movable vertebrae.
The last 4 fused vertebrae in the spine are called the sacrum. The sacrum is a triangular bone located below the lumbar vertebrae and is formed by the fusion of five sacral vertebrae.
The sacrum is formed by the fusion of five vertebrae, while the coccyx, or tailbone, consists of three to five fused vertebrae. Additionally, the sternum is formed from three parts—the manubrium, body, and xiphoid process—though these are not individual bones fused together in the same way as the sacrum and coccyx. These fused structures provide stability and support to the skeletal system.
The lumbar vertebrae in the lower back is typically five in number and unfused.
There are normally 33 vertebrae in infant humans. There are five that will be fused as they become adults to form the sacrum and four that will be fused into coccygeal bones (tail).
The medical term for the five fused vertebrae above the tailbone is the sacrum.
