Searching for neck bones labeled usually leads to one answer: the neck is supported by seven cervical vertebrae, named C1 to C7 from the skull downwards, with the small, free-floating hyoid bone sitting in the front of the throat. The cervical spine protects the spinal cord, carries the weight of the head and allows the neck to nod, turn and tilt. This guide labels each part in words and explains how they fit together. It is general education, not medical advice.
Key takeaways
- There are seven cervical vertebrae, labelled C1 to C7, from the base of the skull to the top of the back.
- C1 is the atlas and C2 is the axis; they are specialised for nodding and rotating the head.
- Discs between most vertebrae act as cushions, and the spinal cord runs through a canal behind them.
- The hyoid bone in the front of the neck is not part of the spine.
- Persistent pain, numbness, weakness or injury needs assessment by a doctor.
The big picture: how the neck is built
The neck, or cervical region, is the top section of the spine. Seven small, ring-shaped vertebrae are stacked on top of each other in a gentle forward curve, called the cervical lordosis. Each vertebra has a solid body at the front, a bony ring at the back that forms a tunnel for the spinal cord, and projections that muscles and ligaments attach to. Between the bodies, from the second and third vertebra downwards, sit discs of tough, fibrous cartilage with a softer centre, which cushion movement.
The cervical spine does a difficult job: it is flexible enough to let you look over your shoulder, yet strong enough to hold up a head that weighs several kilograms, and protective enough to guard the spinal cord, which is delicate.
Neck bones labeled, one by one
| Label | Name | What makes it distinctive |
|---|---|---|
| C1 | Atlas | Ring-shaped with no body; supports the skull and allows nodding (“yes” movement) |
| C2 | Axis | Has a tooth-like peg, the dens, that fits into the atlas and lets the head rotate (“no” movement) |
| C3-C6 | Typical cervical vertebrae | Small bodies, a split (bifid) tip on the spinous process, and openings for blood vessels |
| C7 | Vertebra prominens | Long spinous process you can often feel as a bump at the base of the neck |
| (front of throat) | Hyoid | A U-shaped bone that does not touch any other bone; anchors the tongue and throat muscles |
C1, the atlas
Named after the Greek figure who held up the sky, the atlas carries the skull. It lacks the vertebral body that other vertebrae have, and instead forms a ring with two cup-shaped surfaces on top that cradle the rounded bumps at the base of the skull. This joint mostly allows the head to nod forwards and backwards.
C2, the axis
The axis has a vertical peg, the dens, that rises through the ring of the atlas. The atlas pivots around it, which is why around half of the head’s rotation happens at this top joint. There is no disc between C1 and C2, and ligaments hold the dens in place.
C3 to C6
These four are the “typical” cervical vertebrae. They are small and wide, with oval bodies and a tip on the back, the spinous process, that is often forked. Each also has a small hole on each side of the transverse processes, the foramen transversarium, through which the vertebral arteries run up towards the brain.
C7, the vertebra prominens
C7 marks the transition to the thoracic spine. Its long spinous process is usually the bump you feel at the base of the back of your neck when you tilt your head forwards. It is a handy landmark for doctors and physiotherapists.
What else lives in the neck?
- Intervertebral discs sit between the vertebral bodies from C2-C3 down, absorbing shock and allowing movement.
- The spinal cord runs through the vertebral canal, with nerve roots leaving in pairs through gaps at each level. There are eight pairs of cervical nerves even though there are seven vertebrae.
- Facet joints at the back of each vertebra guide and limit movement.
- Muscles and ligaments such as the trapezius and sternocleidomastoid support the head and let you turn it.
- The hyoid bone floats above the larynx and is held by muscles, not joints. It is relevant in swallowing and speech.

A simple way to remember them
- Count: seven bones in the neck, matching the seven in a giraffe’s neck, a fun fact that is true of nearly all mammals.
- Think of the first two as a pair: the atlas nods, the axis turns.
- Use “C” for cervical and the number for the position, counting down from the skull.
- Find C7 by running a finger down the back of your neck until you reach the biggest bump.
Students often learn the vertebral regions in the order cervical (7), thoracic (12) and lumbar (5), and the neck is the first of these.
Common neck problems in plain language
Neck pain is very common and is often caused by muscle strain or posture, for example from long periods at a desk or looking at a phone. Wear and tear, called cervical spondylosis, can develop with age, and a disc can bulge and press on a nerve. Whiplash injuries happen when the head is thrown suddenly back and forth, often in road accidents. The majority of mild neck pain improves with time, gentle movement and basic pain relief, but an injury after a fall or crash, severe pain, numbness or tingling in the arms, weakness, loss of balance or bladder control, or fever with a stiff neck need urgent medical attention. Always speak to a doctor, pharmacist or physiotherapist about symptoms or treatment, and do not try to manipulate your own neck forcefully.
Keeping the neck healthy
- Set up your screen at eye level and keep your chin level rather than jutting forwards.
- Take regular breaks from sitting, and move your shoulders and neck gently.
- Use a pillow that keeps your neck in line with your spine during sleep.
- Strengthen the upper back and shoulders with regular exercise.
- Wear seatbelts and adjust the headrest so that it sits behind the middle of your head.

Frequently asked questions
How many bones are in the neck?
Seven cervical vertebrae form the neck part of the spine. The hyoid bone in the throat is sometimes counted as a neck bone, but it is not part of the spine.
Which neck bone lets you turn your head?
The atlas (C1) pivots around the dens of the axis (C2), which allows most of the head’s rotation.
Which bone can I feel at the base of my neck?
That bump is usually the spinous process of C7, the vertebra prominens. Sometimes C6 or T1 is similarly prominent.
Why are there eight cervical nerves but seven vertebrae?
The first cervical nerve exits above C1, so the numbering shifts. The C8 nerve leaves between C7 and the first thoracic vertebra.
When should I see a doctor about neck pain?
Seek advice if pain follows an injury, persists for weeks or comes with numbness, weakness, fever, headaches or problems with balance or bladder control. Call emergency services for severe symptoms.
Conclusion
With neck bones labeled, the structure is clear: seven cervical vertebrae from the skull to the shoulders, with a specialised atlas and axis at the top, a landmark C7 at the bottom and the hyoid floating in front. Knowing the names helps you follow what your doctor or physio says, and good posture and regular movement protect this hardworking part of your body.
