1

How many synovial joint surfaces are present at the fifth lumbar vertebral body?

None

2

How many fibrous (Amphiarthrosis) Syndesmosis joint surfaces are present on the L5 vertebral body?

Four

3

How many joint surfaces are present on the vertebral body of the fifth lumbar?

Six

4

How many cartilaginous (Amphiarthrosis) symphysis joint surfaces are present on the vertebral body of L5?

Two

5

What muscle(s) attach to the fifth lumbar vertebral body?

Psoas major

6

What are the attachment sites of the superior corporotransverse ligaments at the L4-L5 intervertebral foramen?

L4 vertebral body and L4-L5 intervertebral disc to the transverse process of L5

7

What are the attachment sites of the inferior corporotransverse ligaments at the L4-L5 intervertebral foramen?

L5 vertebral body and L5-S1 intervertebral disc to the transverse process of L5

8

What characteristic of the L1-L4 pedicle may be used to differentiate it from the L5 segment? Be specific and complete as the difference(s) on a segment from each group.

On cranial view, the lateral surface of the pedicle is apparent on a L1-L4 segment.
At L5 the transverse process originates from the vertebral body, pedicle and lamina-pedicle region

9

What is the generic direction and length of the fifth lumbar transverse process?

It is directed straight lateral and is the shortest of all lumbar transverse processes

10

What accounts for the shortness of the L5 transverse process?

The hip/innominate bones diminish the available space in the transverse plane

11

What parts of the lumbar transverse are homologous to the cervical transverse process parts?

L transverse tubercle = C anterior tubercle; L transverse process = C costal element
L accessory process = C posterior tubercle
L transverse process origin = C true transverse process

12

What muscles may attach to the transverse process of the fifth thoracic vertebra?

Psoas major, Quadratus Lumborum, Longissimus Thoracis, rotator brevis, rotator Longus and intertransversarii

13

What ligaments traditionally attach to the transverse process of the fifth lumbar vertebra?

Lumbosacral, iliolumbar and mammillary-accessory ligaments

14

What is the orientation of the fifth lumbar superior articular facet?

Backward, upward, medial (BUM); typically concave

15

What is the orientation of the fifth lumbar inferior articular facet?

Forward, lateral, downward (FoLD); significant Convexity

16

What is the name given to the congenital condition in which the fifth lumbar spinous process is elongated, the sacrum exhibits spina bifida, and dorsiflexion produces pain?

Knife Clasp Syndrome

17

What muscles will attach to the fifth lumbar spinous process?

Latissimus Dorsi, Iliocostalis Lumborum, Longissimus Thoracis, multifidis, rotator Longus, rotator brevis and interspinalis

18

What is the appearance of the fifth lumbar vertebral body from the lateral view?

Anterior height is greater than posterior height by several millimeters; it appears to form a wedge on a lateral X-Ray view
