Human beings are vertebrates, this means that we belong to the species of mammals that have a backbone, a detail that has allowed us to evolve in an outstanding way, move around the world and adapt to the most diverse environments and environments.
We are born with a certain number of vertebrae, but when we reach adulthood the number is reduced due to the welding of two important bones located in our spine. Do you want to know more? Keep reading because we explain how many vertebrae we have, what they are and what function they perform.
Adults have 24 vertebrae
All human beings are born with 33 vertebrae:
- 7 cervical vertebrae, from C1 to C7.
- 12 thoracic vertebrae, from T1 to T12
- 5 lumbar vertebrae, from L1 to L5
- 5 sacral vertebrae, S1 to S5
- 4 vertebrae in the coccyx, Co1 to Co4
However, when we reach adulthood we will have 24 vertebrae, where did the other 9 go? As it turns out, the 5 vertebrae of the sacrum and the 4 of the coccyx will end up being welded to form the bones of the sacrum and coccyx, leaving only 24 movable and independent vertebrae in our spine.
What are the vertebrae for?
The vertebrae are essential for our correct movement, so each of them has a certain independent movement that allows us to move, turn the head or perform certain actions depending on the region in which they are located. By zone, its function is:
Numbered from C1 to C7, they are the vertebrae located in our neck, therefore they are in charge of allowing the movement of this area to the left, right, up and down, guaranteeing that our head can also move. This area is prone to loading due to tension and incorrect posture, which affects our spinal health.
If you usually suffer from these discomforts, in our article how to relax the cervical we give you tips to keep them in perfect condition.
They are articulated with the rib cage which makes them have limited movement between them, however they are basic to allow the rotation of our torso. They are articulated with the head of the ribs and the rib tubercle to guarantee adequate movement of the area.
They support part of the weight of our upper body and are in charge of creating the concave curvature found at the end of our spine. They mainly allow the movement of forward flexion and extension of our torso, also thanks to them we can flex this area laterally and also rotate it slightly.
A bad movement, an inadequate posture or carrying a lot of weight can cause significant pain in the lower back, so it is necessary to take care of this area properly to prevent discomfort that limits our movement.
