How many bones are fused together to make the tailbone?
number
How many bones make up the sacrum?
Usually 5, I say usually because the body has it's variances amongst individuals. but when looking at a population, 95% will have 5 fused segments. so if this is a test question just go ahead and answer 5
In the human body what is the bone above the tailbone?
The question is not very specific. Most people consider the tail bone to be the sacrum. This is a wide, upside down triangular shaped bone formed by the fusion of 5 separate bones. Above that is the 5th lumbar vertebra. Some people refer to the coccyx as the tail bone. This is the absolute lowest segment of the spine. It is made of 3 small bones that fuse together in early childhood. Above the coccyx bone is the sacrum. From the skull moving down the spine you have 7 cervical vertebrae that make up the neck. Next you have 12 thoracic vertebrae that make up the middle back. The ribs are attached to this section. Next is 5 lumbar vertebrae, or your lower back. Next you have the sacrum, or 5 sacral bones in young children. Then you have the coccyx which in childhood is made up of 3 bones in young children before it fuses into one bone we call the coccyx.
How are the vertebrae numbered in the human spine?
The vertebral column which also none as the spinal column is divided into segments made of 32 bones. The Cervical vertebrae has 7 bones which make up the neck. The Thoracic vertebrae has 12 bones and forms the upper back. The Lumbar vertebrae has 5 bones and forms the lower back. The fifth articulates with the sacrum which in turn articulates with the coccyx. The cervical, thoracic, and lumbar regions consist of individual vertebrae. The Bones are labeled according to the region. Example the Cervical region is labelled C-1-7, the thoracic is labelled T-1-12 and the lumbar area is labled L-1-5. The Sacrum consists of fused components of 5 sacral vertebrae. The Coccyx consists of 3-5 coccygeal vertebrae that have fused together.
What are the small bones called that make up the spine?
This is a tricky question as it is not clear which end of the spine we are referring to. At the head end there is a bone or vertebra upon which the head is resting this is known as the atlas, it does not have a body and its centrum fuses with the axis to provide a pivot for the head to turn on. At the other end of the spine - the tail end the last bones are fused together to form the coccyx, the number may vary from 3 to 5. These bones are rudimanetary and are usually fused together.

NAME the 33 vertebra?
There are...7 Cervical, 12 Thoracic, 5 Lumbar, 5 Sacral (fused together to make the Sacrum), and 4 Caudal also fused together to form the Coccyx, or tailbone.
What part of the spine is both the mechanical weight bearing base of the spinal column and the fused central posterior section of the pelvic girdel?
The sacrum is both the mechanical weight bearing base of the spinal column and the fused central posterior section of the pelvic girdel. The is defined as, one of three bones (sacrum and two pelvic bones) that make up the pelvic ring; consists of five fused sacral vertebrae.
What is the bony makeup of the sacrum?
56 bones make up a sacrum
What if the sacrum does not exist?
The sacrum is the posterior portion of the pelvis. The pelvis is similar to a shallow bowl and the sacrum is one of the three bones that make up the bowl. The sacrum is made of 5 fused vertebra. This lack of the sacrum is called Sacral Agenesis and is a birth defect. The improper development of the sacrum leads to other defects that include abnormalities of the urinary and lower digestive system as well as defects to the legs such as fused legs. The suspected cause of Sacral Agenesis is believed to be Folic Acid deficiency during fetal development.
