| Question | Answer |
|---|---|
| Which regions of the vertebral column has a lordotic curve? | Lumbar & Cervical |
| The articulation of the superior and inferior articulating processes of the cervical spine help to form the: | Intervertebral foramen |
| Which cervical vertebra is referred to as the axis? | C2 |
| The dens is accommodated by the: | Anterior arch of C1 |
| The inner aspect of the intervertebral disk is termed: | Nucleus pulposus |
| The vertebral arch is formed by the: | Pedicles and lamina |
| What is the name of the two bony processes extending laterally from the lamina? | Transverse processes |
| The term vertebra prominens refers to: | C7 |
| The angle between the thoracic zygapophyseal joints and the midsagittal plane is approximately: | 70° |
| An abnormal lateral curvature of the spine is termed: | Scoliosis |
| Which one of the following is defined as a fracture through the pedicles of C2? | Hangmans |
| Ankylosing spondylitis is characterized by: | Spinal rigidity & Paraspinal calcification |
| When the head is in a neutral position, the gonion is at the level of: | C3 |
| The kV range for radiography of the cervical spine is: | 70-80 |
| CT is used to evaluate these in the cervical spine: | Arthritis Herniated disks Spinal trauma |
| Which specific portions of the vertebral column are best demonstrated by the lateral position for the cervicothoracic region? | C4 to T3 |
| How far is the head extended for the AP projection (Fuchs method)? | The head is extended until the mentomeatal line (MML) is near perpendicular to the IR. |
| Which landmarks are aligned for the AP projection in the open mouth position? | Base of the skull & Lower edge of the upper incisors |
| For an AP axial projection of the cervical spine, the CR is directed: | 15° to 20° cephalad |
| For the AP axial projection of the cervical spine in the LAO position, the CR is angled: | 15° cephalad |
| For the lateral projection of the cervicothoracic region, the CR is directed: | Perpendicular to T1 |
| The IR size and orientation for a lateral projection of the cervical spine using a horizontal beam is: | 10 x 12 inches (24 x 30 cm) lengthwise |
| For the AP axial projection to demonstrate the vertebral arch, the CR is directed: | 20° to 30° caudad angle |
| The IR size and orientation for lateral projections of the cervical spine in hyperflexion and hyperextension is: | 10 x 12 inches (24 x 30 cm) lengthwise |
| To demonstrate mobility of the cervical vertebrae, lateral projections of the cervical spine may be taken in: | Hyperflexion & Hyperextension |
| For an AP projection of the thoracic spine, the CR is directed approximately 1 inch below the: | Sternal angle |
| For a left lateral projection of the thoracic spine, the anatomic side marker is placed in the: | Left lower corner |
| he recommended length of exposure time for a lateral projection of the thoracic spine is: | 3 to 4 seconds of exposure time |
| A radiograph of a lateral thoracic spine projection demonstrates poor visibility of the thoracic vertebrae due to the overlap of ribs and lung markings. The image can be improved by: | Using a breathing technique |
