Flashcards in 9/1 Questions Exam 2 Deck (27):
1

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

cervical - upper thoracic region and lumbar region

2

What is the highest level known to demonstrate Hofmann Ligaments?

C6

3

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

4

Lumbar Hofmann ligaments will attach what structures together?

dura mater to lower segmental levels

5

What is the proposed function of the lumbar Hofmann ligaments?

resist cranial movement of the dural sac during flexion

6

What is the proposed function of the proximal root sleve ligament?

resist displacement of the peripheral nerve system in the intervertebral foramen

7

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

8

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

accessory process

9

A styloid process occurs with what frequency and as a result of what condition?

7% occurrence as a result of congenital elongation of the lumbar accessory process

10

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

mammillo-accessory ligament

11

What parts of a vertebra are attached via the mammillo-accessory ligament?

the mammillary process and accessory process of the same segment

12

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

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

13

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

longissimus thoracis and intertransversarii

14

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

psoas major
quadratus lumborum

15

What ligaments attach to the transverse process of a typical lumbar vertebra?

the lumbocostal
mammillo-accessory

16

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

backward, upward, medial (BUM) typically concave

17

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

forward, lateral, downward (FoLD) significant convexity

18

What muscle(s) will attach to the mammillary process?

19

What ligament will attach to the lumbar superior articular process and transverse process?

mammillo-accessory ligament

20

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

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

21

What additional ligaments are said to attach to lumbar articular processes?

transforaminal ligaments

22

What is the joint classification for the typical lumbar zygapophysis?

synovial plane (Diarthrosis arthrodia)

23

How many synovial joints are present on a typical lumbar vertebra?

4

24

What is the position of the lumbar zygapophysis in children?

the zygapophysis lies in the coronal plane

25

What is the position of the lumbar zygapophysis in adults?

the zygapophysis lies in the sagittal plane for L1/L2, L2/L3 and L3/L4;
the zygapophysis lies in the coronal plane for L4/L5 and L5/S1

26

What name is given to zygapophyses between vertebral couples that lie in the same plane?

joint symmetry

27

What names are given to the condition in which one zygapophysis of a vertebral couple lies in the coronal plane or position and the other zygapophysis lies in the sagittal plane or position?

joint asymmetry or joint tropism
