Flashcards in really the last set for ex. 1 sacrum QQ Deck (26):
1

what is the curvature of the superior articular facets of T12?

they are said to be slightly concave

2

what is the curvature of the inferior articular facets of T12?

they are slightly convex

3

what is the orientation of the spinous process of T12?

posterior and horizontal

4

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

accessory process

5

what is the name of the lamina-pedicle junction of a typical lumbar vertebra?

pars-interarticularis

6

what is the name given to the projection on the lumbar superior articular process?

mammillary process

7

what characteristic of the L1-L4 pedicle may be used to differentiate it from the L5 segment?

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

8

what is the typical number of segments that unite to for the adult sacrum?

5 segments

9

line drawn along the dorsal midline of the sacrum is identified as

median sacral crest

10

what forms the median sacral crest?

fused spinous processes and their spinous tubercles

11

line from superior articular process of S1 to the sacral cornu will form what feature?

intermediate sacral crest

12

what forms the intermediate sacral crest?

fused articular processes and their facets

13

what features may be identified along the intermediate sacral crest?

mammillary process of S1 and sacral cornu of S5

14

what is the remnant of the inferior process and facet of S5?

sacral cornu

15

what is the name of the inferior opening of the sacral spinal canal?

sacral hiatus

16

line drawn from transverse process of S1 to the inferior lateral sacral angle will form what feature?

lateral sacral crest

17

what forms the lateral sacral crest?

fused transverse processes and transverse tubercles from S1 to S5

18

what is the sacral tuberosity?

enlarged transverse tubercle of S2

19

from the anterior view, the intervertebral discs of sacrum will be replaced by what feature?

transverse ridges

20

what is the name given to the openings that transmit the ventral sacral nerve rami?

anterior sacral foramina
ventral sacral foramina
ventral pelvic foramina

21

what feature is identified on the lateral surface of S1-S3?

auricular surface

22

what feature does the anterior surface of the superior epiphyseal rim of S1 form?

sacral promontory

23

what is the sacral promontory?

bulging anterior surface of the superior epiphyseal rim of S1

24

what is the name given to the region of bone extending laterally from the S1 vertebral body looking from the base view?

sacral ala

25

what forms the sacral ala?

costal element and true transverse process

26

what part of the sacral ala is derived from the costal element?

anterior 2/3
