The axis is unique because of its odontoid process (dens), which forms a pivot joint with the atlas (C1), allowing rotation of the head from side to side. This region is heavily tested in USMLE Step 1 due to its structural importance and clinical correlations. We begin with the gross anatomy of C2, describing its large vertebral body, dens, superior articular facets for articulation with the atlas, transverse processes, and bifid spinous process. The dens is held in place by the transverse ligament of the atlas, making it a highly specialized structure. Clinical correlations include: Atlanto-axial joint: pivot joint responsible for head rotation. Odontoid fractures: common in trauma and rheumatoid arthritis, with risk of spinal cord compression. Atlanto-axial instability: seen in conditions like Down syndrome and rheumatoid arthritis. Neurological importance: compression can affect the medulla or upper cervical spinal cord, causing life-threatening complications. By linking structural anatomy, functional movement, and clinical relevance, this lecture equips medical students, residents, and clinicians with the knowledge needed for Step 1-style exam questions and for practical understanding in neurology, radiology, and orthopedics. #AxisVertebra #C2Vertebra #AtypicalVertebra #OdontoidProcess #Dens #USMLEStep1 #GrossAnatomy #SpinalAnatomy #ClinicalAnatomy #AtlantoAxialJoint #USMLEPreparation #MedicalStudentsUSA #DoctorEducation #MedicalEducationUSA #Step1Prep #USMLEVideos #NeurologyAnatomy #OrthopedicAnatomy
