Flashcards in Day 9 Deck (27):
1

What characteristic(s) of the L1-L4 vertebral body 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.
In addition, the vertebral body of L5 is more wedge-shaped on lateral view with a much greater anterior height than posterior height

2

What accounts for the direction of the lumbar curve?

the vertebral body and intervertebral disc have a greater anterior height than a posterior height

3

What is the effect of aging on the vertebral body of a lumbar vertebra?

decrease in height, increase in circumference

4

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

six

5

What joint classification will be observed at the vertebral body of a typical lumbar?

cartilaginous (amphiarthrosis) symphysis joint and fibrous (amphiarthrosis) syndesmosis joint

6

What muscles may attach to a typical lumbar vertebral body?

psoas major and psoas minor

7

What is the name given to ligaments which attach the vertebral body to articular process?

transforaminal ligaments

8

What are the attachment sites of the superior transforamninal ligament at the L1-L2 intervertebral foramen?

L1 vertebral body and the inferior articular process of L1

9

What are the attachment sites of the middle transforaminal ligament at the L1-L2 IVF?

intervertebral disc and the inferior articular process of L1

10

What are the attachment sites of the of the inferior transforaminal ligament at the L1-L2 IVF?

L2 vertebral body and the superior articular process of L2

11

What are the attachment sites of the superior corporotransverse ligaments at the L1-L2 IVF?

L1 vertebral body and L1-L2 intervertebral disc to the transverse process of L2

12

What are the attachment sites of the inferior corporotransverse ligaments at the L1-L2 IVF?

L2 vertebral body and L2-L3 intervertebral disc to the transverse process of L2

13

**Hofmann ligaments are identified in which regions along the vertebral column?

cervical- upper thoracic region and lumbar region

14

**Cervical- upper thoracic Hofmann ligaments will attach what structures together?

dura mater to segments above

15

**What is the highest level known to demonstrate Hofmann ligaments?

C6

16

**What is the proposed function of the cervical- upper thoracic Hofmann ligaments?

resist caudal movement of the dural sac; resist gravitational forces on the dura and cord

17

**Lumbar Hofmann ligaments will attach what structures together?

dura mater to lower segments

18

** What is the proposed function of the lumbar Hofmann ligaments?

resist cranial movement of the dural sac during flexion

19

**What osseous conditions of lumbar vertebrae facilitate a spinal tap in this region?

overlap of the laminae, shingling, diminishes;
overlap of spinous processes, imbrication, diminishes

20

**What is the name of the elevation near the origin of the lumbar transverse process?

accessory process

21

**Congenital elongation of the lumbar accessory process results in what feature?

styloid process

22

**Congenital elongation of the lumbar accessory process occurs with what frequency?

7% occurrence

23

What ligament(s) will attach to the lumbar accessory process?

mammillo-accessory ligament

24

What was believed to be entrapped by the mammillo-accessory ligament?

the medial branch of the dorsal ramus of a lumbar spinal nerve

25

What muscle(s) attach to the lumbar accessory process?

longissimus thoracis and intertransversarii

26

What ligament attaches the twelfth rib to the transverse process of L1?

the lumbocostal ligament

27

**What muscles may attach to the transverse process of a typical lumbar vertebra?

psoas major, quadratus lumborum, longissimus thoracis, rotator brevis, rotator longus and intertransversarii
