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).


26 bones of the spinal colomn?

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).


Number of bones of spinal column?

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).


How many vertebrae makes up the spine?

it sometimes depends on the person, but there are roughly 33 in the average personit also depends what you count as vertabrae, as some people might tell you just 24Individual vertebrae named according to region and position, from superior to inferiorCervical - 7 vertebrae (C1-C7) C1 is known as "atlas" and supports the head, C2 is known as "axis"Possesses bifid spinous processes, which is absent in C7Small-bodiedThoracic - 12 vertebrae (T1-T12) Distinguished by the presence of coastal facets for the articulation of the heads of ribsBody is intermediate in size between the cervical and lumbar vertebraeLumbar - 5 vertebrae (L1-L5) Has a large bodyDoes not have coastal facets nor transverse process foraminaSacral - 5 (fused) vertebrae (S1-S5)Coccygeal - 4 (3-5) (fused) vertebrae (Tailbone)


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.

How many bones are in the adults back?

It usually consists of 33 vertebrae and is divided into 5 different types: cervical (7), thoracic (12) lumbar (5), sacral (5 - fused) and coccygeal (4 - fused) vertebrae. Your back bone consists of 7 cervical vertebrae (making the neck), then 12 thoracic vertebrae, and 5 lumbar vertebrae.


What are the bones in the spine?

The bones of the spine are called vertebrae. There are 33 total vertebrae in 5 regions: cervical (7), thoracic (12), lumbar (5), sacral (5), and coccygael (4). (The 5 bones of the sacral region are fused, as are the 4 bones of the coccygeal region.)


How many bones are in the spinal column?

The spinal column is made of 31-33 bones, some of which are fused. There are 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral and 2-4 coccogeal vertebrae.


How many vertebra do human have?

Almost all humans are born with 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. Different textbooks give different answers to this question. The confusion comes from the fact that the two lowest vertebrae -- the sacrum and the coccyx -- are each one bone, but they are made up from smaller bones fused together. There are 24 separate vertebrae; then there is the sacrum, which is formed from 5 fused vertebrae; and finally the coccyx, which is formed from between 3-5 fused vertebrae. Therefore, if the coccyx and sacrum are each classed as one vertebra, then there are 26 vertebrae. If the fused vertebrae are all counted separately, then there are 32-34 vertebrae.


Is there any disc between S1 and S2 vertebrae?

No. The L5-S1 Intervertebral disc is the last disc in the spine because the 5 segments of the sacrum and the 4 segments of the coccyx are fused (though they are seperated from each other by a ligament).


Do you have more then one bone in your spine?

Yes. There are 33 bones in the vertebral column in a human. These bones are called vertebrae and are categorized in 5 regions: cervical (7 bones), thoracic (12), lumbar (5), sacral (5 fused), and coccygeal (4 fused).

Where is the invertebrate in the human body?

Assuming you mean vertebrae; The human spine is made up of 33 vertebrae (Sungular: vertebra.) There are four sections of vertebrae. The cervical vertebrae is is made up of 7 vertebrae and makes up the neck. The thoracic vertebrae makes up the upper back and contains 12 vertebrae. the lumbar vertebrae area makes up the lower back between the thoracic vetrtabrae and the sacral curve, made up of 5 vertebrae. Lastly, The tailbone area is below the lumbar section and called the sacral curve. 5 vertebrae make up the sacrum and 4 are fused to make the tailbone. All vertebrae but the sacral curve section are separated by invertebral discs.
