The first cervical vertebra, atlas, is unique in the sense that it possesses neither a body nor spinous process. It consists of an anterior and posterior arch extending between two lateral masses, forming a closed triangular 'ring' that accommodates the brainstem. Each lateral mass contains superior and inferior facets The first cervical vertebra, or atlas, articulates with the occiput rostrally and the axis caudally. It consists of two articulating lateral masses that are connected anteriorly and posteriorly by neural arches (Fig. 2-3). The lateral masses are also connected coronally by the transverse atlantal ligament The atlas, or C1, is the first cervical vertebra and is shaped to allow articulation with the odontoid process of C2 and the skull. It is unique in that it has no vertebral body. The posterior arches of C1 extend posteriorly and medially from the lateral masses to terminate in the short posterior tubercle By convention, the cervical vertebrae are numbered, with the first one (C1) closest to the skull and higher numbered vertebrae (C2-C7) proceeding away from the skull and down the spine. The general characteristics of the third through sixth cervical vertebrae are described here
Each cervical vertebra is named by its position in order from superior (C1 or first cervical vertebra) to inferior (C7 or seventh cervical vertebra). The C1 vertebra, which holds up the skull, is named the atlas after the mythological titan Atlas who similarly held the Earth on his shoulders Cervical one is also called the atlas, as it supports the weight of your skull. Cervical two is called the axis, as it is the one essential for allowing rotation to occur in the cervical spine. Both the atlas and axis are small, flat vertebrae. The atlas at cervical level one is a flat, ring-shaped vertebra The cervical spine is made up of two anatomically and functionally different segments. These two segments work together to produce rotation, lateral flexion, flexion and extension of the head and neck. It is made up of 7 vertebrae. The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively
The first cervical vertebra is also known as the atlas. It articulates with the skull and with the adjacent vertebra - the axis. The major distinguishing feature of the atlas is that it does not have a vertebral body.
