C7 vertebra

C7 Vertebra

The C7 vertebra is the seventh cervical vertebra of the spine. It is also known as the vertebra prominens due to its prominent role in the structure and function of the neck and upper body.

Anatomy

The C7 vertebra is unique among the cervical vertebrae as it has a long and prominent spinous process, which is palpable at the base of the neck. This process serves as an attachment point for several muscles and ligaments, including the trapezius muscle and nuchal ligament.

Like other cervical vertebrae, the C7 has a small vertebral body, a large vertebral foramen, and transverse processes that contain foramina transversaria. These structures allow for the passage of the vertebral artery and vertebral vein, as well as the vertebral nerve.

Function

The C7 vertebra plays a crucial role in supporting the head and allowing for its range of motion. It also provides a pathway for important blood vessels and nerves. The C7 is often considered the "neck's base," providing a pivotal point for head and neck movement.

Clinical significance

Injuries or conditions affecting the C7 vertebra can lead to significant health issues. These can include cervical spondylosis, herniated disc, and spinal stenosis. Symptoms can range from neck pain and stiffness to more severe problems such as numbness, weakness, or tingling in the arms or hands.
