ATLAS VERTEBRA Meaning and
Definition
-
The atlas vertebra, also known as the C1 vertebra, is the uppermost bone in the vertebral column of mammals, including humans. It is named after Atlas, a figure in Greek mythology who was condemned to hold the heavens on his shoulders, as it supports the weight of the skull. The atlas vertebra is situated at the base of the skull, forming a hinge joint with the occipital condyles.
Structurally, the atlas vertebra is unique compared to the other vertebrae in the spine. It lacks a vertebral body, which is the large, round portion found in the other cervical vertebrae. Instead, it consists of a ring-shaped bone with two lateral masses on either side. The lateral masses articulate with the occipital condyles, enabling nodding movements of the head. The atlas also features two prominent bony structures called transverse processes, which project laterally. These processes serve as sites of attachment for important muscles and ligaments that stabilize the head and neck.
The primary function of the atlas vertebra is to support the weight of the skull and facilitate movements of the head. It allows for flexion, extension, and rotation of the neck, playing a vital role in activities such as nodding, tilting, and turning the head. The atlas vertebra also provides protection for delicate structures, such as the spinal cord and blood vessels, passing through the vertebral column.

Etymology of ATLAS VERTEBRA
The term atlas vertebra is derived from the Latin word Atlas, which refers to a Greek mythological figure named Atlas.
