  • As your head rotates, the cervical spine has the most range of motion of any part of the spine. (atlantainjurylawblog.com)
Brainstem1
  • Every nerve that travels down the spinal cord has to pass through the fragile donut shaped vertebra that wraps around the brainstem called the atlas! (mymisalignment.com)
Diagnosis1
  • She was given a diagnosis of cervical dystonia and initiated on trihexyphenidyl and referred to our facility for botulinum neurotoxin therapy (BoNT). (neurology.org)
Radiographs2
  • Conclusion: The overall results of the study suggest that plain cervical spine radiographs are still reliable if used as the sole screening modality in the detection of C1 and C2 fractures in rural setting where availability of CT is scarce. (ispub.com)
  • A total of 112 consecutive patients with blunt head trauma in whom plain cervical spine radiographs and routine CT scan of C1 and C2 performed were included in this study. (ispub.com)
Adjustment2
  • The actual atlas adjustment is incredibly gentle and most patients do not even feel the change in alignment occurring. (cure-back-pain.org)
  • Adjustment is usually a multi-step procedure, with several motions being completed to successfully implement resolution of the atlas misalignment. (cure-back-pain.org)
Vertebral arteries2
  • 90% of blood flow to the midbrain is from the vertebral arteries, which pass through the atlas vertebra. (atlas-specific.com)
  • Unlike the other parts of the spine, the cervical spine has transverse foramina in each vertebra for the vertebral arteries that supply blood to the brain. (medscape.com)
Odontoid4
Neurologic1
  • Early identification, conservative treatment with immobilization of the cervical spine, and anti-inflammatory drugs are imperative to avoid neurologic complications. (neurology.org)
Cord2
  • The Dura Mater - A membrane sack encloses the brain and spinal cord, called the Dura Mater, and is attached to the Atlas and the Axis. (uccenters.com)
  • The spinal cord is protected by the cervical spine, which provides support for the head and allows for a significant amount of range of motion (ROM). (medscape.com)
Joints2
  • These joints of Luschka, also known as uncovertebral joints, are not present in the embryologic development of the cervical spine but arise as a result of the degenerative and adaptive changes of annular tissue to stresses and loads. (medscape.com)
  • With this maneuver, the vast majority of cervical motion is produced at the occipitoatlantal and atlantoaxial joints. (asahq.org)
Consists1
  • OverviewThis Axis Scientific model collection consists of the different divisions of the human spine. (anatomywarehouse.com)
