Along the upper surface of each pedicle is a half- moon- shaped area called the

superior vertebral notch

The processes that project upward are called the

superior articular processes

The zygapophyseal joints form an angle open from

45° to 65°

The portion of each lamina between the superior and inferior articular processes is the

pars interarticularis

is inferior to the lumbar vertebrae

sacrum

or wings, of the sacrum are large masses of bone lateral to the first sacral segment

alae,

The anterior ridge of the body of the first sacral segment helps form the posterior wall of the inlet of the true pelvis and is termed the

promontory

Posterior to the body of the first sacral segment is the opening to the

sacral canal

are small tubercles that represent the inferior articular processes pro jecting inferiorly

sacral horns

Which radiographic position best demonstrates the intervertebral foramina?

Lateral position

the sacroiliac joints lie at an oblique angle of __________ degree to the coronal plane

30 degree

what is the classification type of the intervertebral joint?

cartilaginous

which specific set of zygapophyseal joints is demonstrated with an LAO position?

right (upside)

Patients should be asked to empty the urinary bladder before performing which projections of the vertebral column?

AP of sacrum and coccyx

The ______, which is the eye of the "scottie dog," should be near the center of the vertebral body on a correctly oblique lumber spine

pedicle

Cassette: 14 by 17
CR: highest point of iliac crest. Internally rotate feet ~10 degrees.

PA Lumbar

Which of the following is the essential projection used to demonstrate the zygapophyseal joints of the lumbar spine?

AP oblique, RPO and LPO positions

A radiograph of an LPO projection of the L-spine reveals that the downside pedicles are projected toward the posterior aspect of the vertebral bodies. What must be done in a heartbeat to correct this error before you re-expose your patient to more radiation?

decrease rotation of the spine
