Flashcards in back and SC Deck (23):
1

intrinsic back muscles

erector spinae and transversospinalis

2

muscles that do flexion of the spine

psoas major and rectus abdominus

3

muscles of teh anterolateral abdo wall

transverse abdominus, internal oblique, extrenal oblique

4

where do spinal nerves enter/exit

intervertebral foramen

5

what are the joints in the spine called

facet joints (betweeen articular processes). can be affected by arthritis (the discs however are fibrocartilage so can never osscify)

6

between with vertebrae is there no intervertebral disc

c1-c2

7

where is teh ligamentum flavum found

connects adjacent laminae, it is therefore posterior to teh SC

8

role of posterior longitudinal ligament

prevents over flexion. it is narrow and weak

9

role of anterior long ligament

prevents over extension. it is broad and strong

10

ligament that connects the tips of teh spinous processes

supraspinous. it is strong and fibrous

11

describe c1

no body or spinous process. ATLAS

12

describe c2

odontoid process. AXIS

13

c7

vertebrae prominans

14

ligament that connects superior and inferior surfaces of adjacent spinous processes

interspinous. it is weak and membranous

15

atlantooccipital joint

between occipital condyles and the superior articular facets of the atlas. synovial joints. flexion and extension of the neck

16

joint in the neck mainly for rotation of head

atlantoaxial joint
2 between inferior articular facets and superior facets and one between odontoid process and anterior arch of atlas.
all 3 are synovial

17

describe the bony features on teh sacrum

sacral prominentory, anterior sacral formaniae, posterior sacral foraminae, sacral canal, sacral hiatus

18

what passes in the sacral canal

cauda equina

19

caudal anaesthesia

anaesthetic injected into the sacral hiatus to target teh sacral spinal nerve roots of teh cauda equina

20

where does teh SC begin and end

foramen magnum, ends at L2

21

level of cauda equina

L2-C0

22

what is a laminectomy

removal of one or more spinous processes and the adjacent lamina (articular processes aren't removed)

23

which logaments are crossed in laminectomy

ligamentum flavum and supraspinous and interspinous
