generic shape of typical lumbar vertebral body from CRANIAL view

reniform or kidney shaped

2

accounts for direction of the lumbar curve

the vertebral body and intervertebral disc = greater anterior height than posterior height

7

muscles attached to the first lumbar vertebral body

psoas maj.
psoas min.

8

muscles attached from L2-L4 vertebral bodies

psoas maj.

9

psoas minor will ONLY attach to the vertebral body of which segments

T12, L1

10

name given to ligaments that attach the vertebral body to articular process

transforaminal ligaments

11

ligaments that attach the vertebral body to the transverse process

corporotransverse ligaments

12

hofmann ligaments are identified in which regions along the vertebral column

cervical-upper thoracic region and lumbar region

13

cervical- upper thoracic hofmann ligaments will attach what structures together

dura mater to segment above

14

highest level known to demonstrate hofmann ligaments

C6

15

proposed function of the cervical- upper thoracic hofmann ligaments

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

16

lumbar Hofmann ligament attaches what structures together

dura mater to lower segmental levels

17

proposed function of the lumbar Hofmann ligaments

resist cranial movement of dural sac during flexion

18

proposed function of the proximal root sleeve ligament

resist displacement of PNS in the IVF

19

osseous conditions of lumbar vertebrae facilitating a spinal tap in this region

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

20

name of elevation near the origins of the lumbar transverse process

accessory process

21

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

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

22

ligaments that attach to the lumbar accessory process

mammillo-accessory ligament

23

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

mammillary process and accessory process of the same segment

24

believed to be entrapped by the mammillo-accessory ligament

medial branch of the dorsal rams of a lumbar spinal nerve

25

muscle(s) that attach to the lumbar accessory process
