SPINE AND PELVIS PROCEDURES

How many movable joints can be visualized in an AP pelvis radiograph? A. 2 B. 3 C. 4 D. 5

D. 5 Two sacroiliac joints, two hip joints and the symphysis pubis

What is the most inferior portion of the pelvis called? A. Ischial spine B. Symphysis pubis C. Ischial tuberosity D. Inferior rami of the pubic bones

D. Inferior rami of the pubic bones

Which of the following projects posteriorly off the two laminae of a typical vertebra? A. Transverse process B. Superior articulating process C. Inferior articulating process D. Spinous process

D. Spinous process The two laminae join together and form a spinous process posteriorly

When viewed from the anatomic position, what type of natural curve is found in the thoracic spine? A. Concave B. Convex C. Scoliotic D. Myoptic

A. Concave

Which of the following project off the posterior, lateral borders of the vertebral body? A. Pedicles B. Laminae C. Spinous process D. Articular processes

A. Pedicles Projecting directly off the posterior, lateral borders of a vertebral body are two pedicles.

The spinal cord terminates at the level of which vertebra? A. 12th thoracic B. 2nd lumbar C. 5th lumbar D. 1st sacral

B. 2nd lumbar The spinal cord terminates at the level of L1-L2 with a tapered end called the conus medullaris.

When viewed from the anatomic position, the natural curve of the lumbar spine is classified as what type? A. Concave B. Convex C. Spondylotic D. Scoliotic

B. Convex

Spina bifida is caused by which of the following? A. Pedicles not fusing to the body B. Pedicles not fusing with the laminae C. Posterior laminae not fusing D. Laminae and transverse processes fused

C. Posterior laminae not fusing Spina bifida is a congenital anomaly where the laminae do not unite posteriorly, leaving an opening where the spinous process usually forms.

What are the lateral projections on a typical vertebra called? A. Spinous processes B. Articular processes C. Transverse processes D. Pedicles

C. Transverse processes The transverse processes project laterally from the junction of the pedicles and laminae.

Which of the following passes through the transverse foramina of the cervical vertebrae? A. Carotid artery B. Jugular vein C. Vertebral artery D. Subclavian artery

C. Vertebral artery

What is the posterior, bony ring of a typical vertebra called? A. Pedicle B. Lamina C. Vertebral body D. Vertebral arch

D. Vertebral arch The typical vertebra consists of two main parts, the body and the vertebral arch. The vertebral arch forms an opening called the vertebral foramen.
