The vertebrae that make up the cervical backbone are the smallest seven throughout the spinal column. These bones give the neck construction, help the cranium, and shield the spinal wire, amongst different capabilities.
Every vertebra is formed like an odd Mardi Gras masks when considered from the highest. A protrusion on the bottom known as the spinous course of extends backward and barely downward. That is the place ligaments and muscle groups connect to the vertebra.
The our bodies of the vertebrae are related to 1 one other. Many ligaments, or bands of connective tissue, wrap across the spinal column and join its vertebrae. In addition they forestall extreme motion that might harm the spinal column.
Intervertebral discs, small cartilage cushions, pad the areas between the vertebrae. The discs enable motion of the spinal column and performance like shock absorbers.
A letter and quantity determine vertebrae. Within the cervical column, the vertebrae are C1 by C7. The “C” stands for “cervical.”
The entire cervical vertebrae flex and prolong the neck, however some have extra particular capabilities, together with:
- C1: The primary vertebra within the column closest to the cranium is also called the atlas. It varieties the joint that connects the cranium and the spinal column.
- C2: Also referred to as the axis, it creates a pivot that enables C1 to rotate, thus giving the top larger vary of movement.
- C7: The final of the cervical vertebrae, C7 has an extra-long spinous course of. This is without doubt one of the bones that protrude by the pores and skin in the back of the neck.
Fracture to any vertebra is taken into account a medical emergency, however harm to the cervical vertebrae is very crucial. Fracture and harm to the C2 vertebra is frequent with high-force trauma, and should trigger loss of life or paralysis.
