Anatomy of the c2 c5 spinal motion segments.

C2 anatomy. Atlas c1 the atlas is ring shaped and does not have a body unlike the rest of the vertebrae. Its most prominent feature is the odontoid process or dens which is embryologically the body of the atlas c1 12. These two vertebrae have different anatomy than the rest of the spine.

The c1 vertebra also called atlas is shaped like a ring. S upports the head 2 lateral masses connected by anterior arch and posterior arch the transverse ligament retains the dens against the anterior arch c1 atlas. C0 occipital condyles.

The axis is the second cervical vertebra commonly called c2it is an atypical cervical vertebra with unique features and important relations that make it easily recognisable. Vertebrae and joints from c2 through c5. Flank the foramen magnum oval tubercle for alar ligament c0 occipital condyles.

The second cervical vertebra c2 is called the axis as it is the line upon which the head and c1 rotate upon. The unique features of c2 anatomy and its articulations complicate assessment of its pathology. The atlas and axis are specialized to allow a.

It plays an important role in rotation of the head with the majority of movement occurring around. The atlanto axial articulation is a complex of three synovial joints which join the atlas c1 to the axis c2. By the atlanto axial joint it forms the pivot upon which the first cervical vertebra the atlas which carries the head rotates.

Gross anatomy articulations paired lateral atlanto axial joints. The c1 vertebra is formed like a ring that sits on top of c2. The c1 vertebra connects the skull to the cervical spine.

Anatomy of the c1 c2 vertebrae and spinal segment. C1 and c2 vertebrae. The c2 vertebra has an upward facing long bony process called the dens.

In anatomy the atlas c1 is the most superior first cervical vertebra of the spine. Classified as planar type joint between the lateral masses of c1. In anatomy the second cervical vertebra c2 of the spine is named the axis from latin axis axle or epistropheus.

C0 c1 c2 anatomy. C0 c1 c2 anatomy. The c1 c2 vertebrae and spinal segment include the following structures.

The vertebrae in the c2 c5 motion segments are held together with ligaments and connected by paired facet joints running down the back of the spine. Note uniquely shaped atlas and axis c1 and c2. Fused remnants of the atlas body have become part of c2 where they.

The atlas is the topmost vertebra and with the axis forms the joint connecting the skull and spine. This video is an animated demonstration of c1 c2 instability and is not meant to be an exact anatomical model. These joints are synovial joints that contain.

The most distinctive characteristic of this bone is the strong odontoid process known as the dens which rises perpendicularly from the upper. It is named for the atlas of greek mythology because it supports the globe of the head which is the skull.
