The swimmer's technique demonstrates the cervicothoracic region in which projection?

a. AP
b. Lateral
c. AP axial
d. AP axial oblique

Answer :

Final answer:

The swimmer's technique demonstrates the cervicothoracic region in an AP axial projection. The correct option is c. AP axial.

Explanation:

The question 'The swimmer's technique demonstrates the cervicothoracic region in which projection?' is regarding a type of imaging view used in radiology to evaluate the spine, specifically the cervicothoracic region. This region comprises the cervical and upper thoracic vertebrae, and different projections are used to view it. The imaging projection that best demonstrates the cervicothoracic region is an AP axial projection, which is an anterior-posterior view with an axial (upward or downward) tilt to the x-ray beam. This projection allows for better visualization of the vertebrae without the shoulders obscuring them.

Regarding the motion in the vertebral column, the question 'Which region of the vertebral column has the greatest range of motion for rotation?' pertains to the biomechanics of the spine. The correct answer to this question is the thoracic region, which, because of its rib attachments and flattened and vertically positioned articular processes, allows for the greatest range of rotation within the vertebral column. This contrasts with the cervical region that allows for extensive motions like flexion, extension, lateral flexion, and rotation but is not the region with the greatest range for rotation specifically.
