C7

The 7th cervical (C7) vertebra is the largest and most inferior vertebra in the neck region. Unlike the other cervical vertebrae, the C7 has a large spinous process that protrudes posteriorly toward the skin at the back of the neck. This spinous process can be easily seen and felt at the base of the neck, making it a prominent landmark of the skeleton and giving the C7 the name vertebra prominens.

The C7 is located in the spinal column inferior to the 6th cervical (C6) vertebra and superior to the first thoracic (T1) vertebra.
