Understanding Cervical spine
Your neck has seven small bones. These bones are called vertebrae. They stack on top of each other.
Related glossary terms: Adjustment, Disc herniation, Spinal stenosis.
This stack forms your neck. It holds up your head. Your head weighs 10 to 12 pounds.
The neck also keeps your spinal cord safe. The spinal cord is a bundle of nerves. It sends messages from your brain to your body.
Your neck moves in many ways. You can turn, tilt. And nod your head. This makes your neck flexible but easy to hurt.
Each neck bone has a job. The first bone, C1, is called the atlas. It lets your head nod up and down.
The second bone, C2, is called the axis. It has a peg that lets your head turn side to side.
The other bones, C3 to C7, help your neck stay strong. They support your neck muscles and ligaments.
Between each bone are discs. These discs act like cushions. They stop bones from rubbing together.
How Cervical spine Works?
Your neck protects your spinal cord. It lets you move at the same time. The bones form a tunnel for the cord.
Nerves branch out from the cord. They go through small holes between the bones. These nerves send signals to your arms and shoulders.
When you lift your arm, your brain sends a command. The nerves in your neck carry it. If nerves get squeezed, it can hurt.
This can cause pain or tingling. It can make your arms feel weak. Poor posture or injuries can do this.
Your neck moves because of joints. These joints are called facet joints. They work like hinges.
They let your neck bend forward and backward. They also let it bend side to side. Muscles and ligaments help keep your neck steady.
But your neck moves a lot. This makes it easy to strain or sprain. Whiplash or looking down at your phone can hurt it.
Why Cervical spine Matters?
A healthy neck helps you every day. It lets you move without pain. It helps you stand up straight.
If your neck has problems, it can hurt. You might get headaches or feel dizzy. Your arms or hands might feel numb.
