Best Answer

You have 7 unfused cervical vertebrae. You have 12 unfused thoracic vertebrae. You have 5 unfused lumber vertebrae. The five vetebrae are fused in case of the sacrum. That is the need of the hour. You can not support the hip bones with out that fusion. Then there are few fused vertebrae in coccyx.

33 separate vertebrae. By adulthood, most have only 24. This is due to the fusion of the vertebrae in certain parts of the spine during normal development. I am the jokers girlfriend.

How many bones are fused together to make the sacrum?

The sacrum is composed of 5 fused vertabrae.


How many bones are there in an adult backbone?

There are 33 vertebrae in the human spine. (7 cervicals, 12 thoracic, 5 lumbar, 5 that fuse into the sacrum and 4 that fuse into the coccyx.). The sacrum and coccyx are already fused into their respective bones at birth.There are 33 vertebrate in the human spine. There are 7 cervical, 12 thoracic, 5 lumbar, 5 that fuse into the sacrum, and 4 that fuse into the coccyx.


How many vertebrae does an adult have?

24. A fetus has 33, but later the bones of the sacrum and coccyx fuse together.


Do people have different numbers of vertebrae?

Yes, there are differences between people of the number of vertebrae they have. There are usually 24 vertebrae in a human (not counting the sacrum and coccyx at the bottom of the spine) but not always. Some people have an extra lumbar vertebra, and they will have a total of 25 (not counting the sacrum and coccyx).Some anatomists don't count the sacrum and coccyx as vertebrae, others count them as one vertebra each. But the coccyx can be composed of up to 5 separate vertebrae. Therefore, if you count the sacrum as 1 and the coccyx as 5 (more on that below), then the maximum total number could be counted up to 31 (but usually are not).Here is how they add up:There are five sections of the spine: cervical (neck), thoracic (trunk/back), lumbar (low back), sacrum (attaches other vertebrae to the pelvis) and the coccyx (tailbone).Cervical vertebrae usually do not vary in number, there are 7.Thoracic vertebrae also usually do not vary, there are 12.Lumbar vertebrae are fairly often different in number from person to person. Usually there are 5, but many people have 6.The sacrum is one vertebra that was formed in utero (before birth) during fetal development from a group of vertebrae that become fused together. How many of these fuse can vary. This is a reason for some people to have 6 lumbar vertebrae, the extra one is one that did not fuse to become part of the sacrum and then remains to count as a separate lumbar vertebra, the 6th one just before the sacrum.The coccyx usually includes 4 vertebrae but can vary between 3-5. They can be all separate or all fused together or some fused and some separate.

What are the 26 small backbones?

Typically there are 7 vertebrae in the neck called cervical vertebrae. They are commonly called C1-C7. The first cervical vertebra is also called the atlas, and the second, the axis. Typically there are twelve thoracic vertebrae to which the ribs attach. Typically there are five lumbar vertebrae in the lower back. Caudal ('toward the tail' or below in the standing position) to the lumbar vertebrae is the sacrum. Caudal the the sacrum is the coccyx. It is often called the tailbone. Commonly, the coccyx is formed by two or three segments. Many people have a sixth lumbar vertebra which is usually a part of the sacrum which did not fuse to the other segments of the sacrum during development. Sometimes a vertebra, usually a thoracic vertebra, fully develops on only one side, so one might say there are 12 vertebrae on one side, and 11 on the other. That is called a hemivertebra. Sometimes 2 vertebrae are fused together, making one bone instead of two.

How many spinal vertebra does a human have?

There are 33 vertebrae in the spinal cord of a human being. They are broadly categorized into 5 areas. They are called the cervical, thoracic, lumbar, sacrum & coccyx vertebra. The upper 3 areas have a total of 24 vertebrae, which includes 7 cervical vertebrae, 12 thoracic vertebrae & 5 lumbar vertebrae. Sometimes the lumbar region, may have an additional vertebra, it does happen - but it is rare. 5 vertebrae are fused together to form the sacrum & 3 vertebrae form the end of the spinal column which is the coccyx.

How many vertebrae does a 13-year old male have?

24 There are typically 7 neck vertebrae, 12 thoracic and 5 lumbar vertebrae. A few percent of folks have one more or one less due to fusion or a lumbar vertebra with the Sacrum or non union of the normally fused 5 sacral segments. Others have fused vertebra elsewhere in the spine.
