Cervical spine

Cervical Spine

The Cervical Spine (pronounced: SIR-vi-kul SPINE) is the uppermost part of the vertebral column, also known as the neck region.

Etymology

The term "cervical" originates from the Latin word "cervix" which means neck, while "spine" is derived from the Latin word "spina" which means thorn or backbone.

Anatomy

The cervical spine is made up of seven vertebrae, labeled C1 through to C7. The cervical spine starts just below the skull and ends at the beginning of the thoracic spine. It has an inward curve known as a lordotic curve. The cervical spine is extremely flexible and supports the weight of the head.

Vertebrae

The seven vertebrae of the cervical spine are:

C1 Vertebra - Also known as the Atlas, it supports the skull.
C2 Vertebra - Also known as the Axis, it allows the head to rotate.
C3-C7 Vertebrae - These vertebrae protect the spinal cord and provide structural support for the neck.
