The link should help. It says 10% of adults. I know this because I have the same condition except I wasn't technically an adult when I was diagnosed. I hope the link helped.

How many cervical thoracic and lumbar vertebrae are there?
Absolutely! They have features unique to the region they are found in, relating to structure and therefore function. Typical cervical vertebrae (C3-C6) usually have bifid spinous processes which point slightly inferiorly. The spinous processes on lumbar vertebrae are oblong in shape and point directly posteriorly. The articular facets of cervical vertebrae face superior-inferiorly, whereas lumbar articular facets face medial-laterally. Cervical vertebrae have transverse foramen on right and left(containing the vertebral arteries), lumbar have none. They have mamillary processes on their superior articular processes. The bodies of lumbar vertebra are larger and thicker than cervical vertebrae, though they are oval/kidney shaped shaped in both regions. The transverse processes of lumbar vertebrae are much longer, for muscle attachment. Cervical vertebrae have anterior and posterior tubercles extending from their transverse processes. The pedicles of lumbar vertebrae are slightly longer and more defined than those of cervical vertebrae. I think that covers everything, let me know if you think of anything else!
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.
The spine is compose of how many movable segments called vertebrae?
There are 5 cervical vertebrae (neck bones) and 12 thoracic vertebrae (in the rib cage area) and 5 lumbar vertebrae (in the small of the back) and 6 sacral vertebrae ( the back of your hips, and in adults are normally fused into 1 bony structure) and 3 to 5 coccyx bones (tail bones) Say, between 31 and 33 vertebrae, total.
How many vertebra does a dog have?
The average dog has 26 vertebrae. 7 cervical, 13 thoracic, and 6 lumbar. Some breeds such as the English Bulldog may frequently have a 7th lumbar vertebra, or a portion of a vertebra called a transitional vertebra.
Bones in your spine?
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).
How many lumbar vertebrae revealed in the patient during lumbalisation?

How many lumbare vertabre in a ferret?
Ferrets have 5 or 6 lumbar vertebrae.
How many vertebra do cows have?
Cows have 13 thoracic and 6 lumbar vertebrae. If you consider the backbone as composed of the cervical, thoracic, and lumbar vertebrae, there would be a total of 24 vertebrae.
How many lumbar for Arabian horse?
Arabians like all other horse breeds tend to have 6 lumbar vertebrae, however in some cases the vertebrae can become fused together creating the illusion that there are only 5 of the lumbar vertebrae. Also in all breeds of horse there is the possibility for one of the vertebrae to just not be there, but this is not unique to Arabians as it was once thought to be.
Can a human have 34 vertebrae?
Yes. The human spine is made up of three parts, the cervical spine(neck), the thoracic(middle), and the lumbar (lower back). The lumbar consists of 5 vertebrae in the average adult human, but may also only have 4 or 6 vertebrae depending on the individual, although this is not as common. There can be sacralization of the 5th lower lumbar resulting in only 4 lumber vertebrae, or a vertebrae of the sacrum where the individual has an extra 6th lumbar vertebrae. While all adults have 7 cervical vertebrae there is much more variation in the thoracic and lumbar vertebrae. The thoracic too may have a 13th vertebrae resulting in an extra rib. And as mentioned before the lumbar may have 4-6 vertebrae depending on the individual.
How many lumbar vertebrae are on the human body?
The human spine is made up of three parts, the cervical spine(neck), the thoracic(middle), and the lumbar (lower back). The lumbar consists of 5 vertebrae in the average adult human, but may also only have 4 or 6 vertebrae depending on the individual, although this is not as common.
How many vertebrae does a monkey have?
Old World Monkeys all have 7 neck vertebrae and 13 thoracic vertebrae. In the lumbar region, the number is either 6 or 7, and then they possess a sacrum made of a few vertebral segments, plus a tail.
Is it normal to have 6 lumbar spines?
Everybody has only one lumbar spine. You may mean six lumbar vertebrae, instead of the normal five. This is an anatomical variation, not in itself e problem.
