Cervical vertebrae are the seven vertebrae that form the uppermost part of the vertebral column, supporting the skull and enabling a wide range of head movements. They are uniquely characterized by smaller size, the presence of transverse foramina, and a bifid spinous process in most cases, distinguishing them from other vertebrae.

Cervical Vertebrae

Cervical vertebrae

The vertebral column, also known as the spine, is a flexible, segmented structure that provides support and protection for the spinal cord while allowing a wide range of motion. It consists of 33 vertebrae divided into five regions: cervical, thoracic, lumbar, sacral, and coccygeal, each with specific functions and characteristics.

Head movements are crucial for nonverbal communication, providing cues about attention, emotions, and social interactions. They also play a vital role in balance and spatial orientation by coordinating with the vestibular system and visual inputs.

Transverse foramina are openings in the transverse processes of cervical vertebrae, which allow for the passage of the vertebral artery, vein, and sympathetic nerves. These structures are crucial for supplying blood to the brain and are unique to the cervical spine, distinguishing it from other spinal regions.

A bifid spinous process is a feature where the spinous process of a vertebra splits into two distinct projections, commonly seen in the cervical vertebrae of the spine. This anatomical variation is most prominent in the second cervical vertebra, known as the axis, and can be important in clinical assessments and surgical procedures involving the cervical spine.
