31

What part of the central nervous system is present in the lumbar spine?

the conus medullaris is typically present in the vertebral foramen of L1

32

What part of the peripheral nervous system is present in the lumbar spine?

the cauda equina is typically present in the vertebral foramina of L2-L4

33

Beginning with the L1 transverse process, what is the generic direction and relative length of each succeeding lumbar transverse process?

each transverse process is directed straight lateral and increases in length from L1-L3. L4 then begins to decrease in length

34

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

accessory process

35

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

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

36

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

mammillo-accessory ligament

37

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

the mammillary process and accessory process of the same segment

38

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

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

39

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

longissimus thoracis and intertransversarii

40

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

41

What ligaments attach to a typical lumbar vertebra?

the lumbocostal, mammillo-accessory and intertransverse ligaments

42

What joint classifications are present at the transverse process of a typical lumbar?

fibrous (amphiarthrosis) syndesmosis

43

What are the posterior elements of the vertebra?

zygapophysis, lamina and spinous process

44

What are the anterior elements of the vertebra?

vertebral body and pedicle

45

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

backward, upward, medial (BUM); typically concave

46

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

Forward, lateral, downward (FoLD); significant convexity

47

What muscle(s) attach to the mammillary process?

multifidis and intertransversarii

48

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

mammillo-accessory ligament

49

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

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

50

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

transforaminal ligaments

51

What is the joint classification for the typical lumbar zygapophysis?

synovial plane (diarthrosis arthrodia)

52

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

four

53

What is the position of the lumbar zygapophysis in children?

the zygapophysis lies in the coronal plane

54

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

55

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

joint symmetry

56

What names are given to the condition in which the right 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

57

Define or describe joint tropism.

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

58

What is the name(s) of the condition in which the typical lumbar spinous process increases in length due to the aging process?

Baastrup's syndrome or 'kissing spines'

59

What muscles will attach to the typical lumbar spinous process?

latissimus dorsi, serratus posterior inferior, iliocostalis lumborum, longissimus thoracis, spinalis thoracis, multifidis, rotator longus, rotator brevis and interspinalis
