1

4 Purposes of the Spine

Provides support for trunk and skull
Encloses and protects the spinal cord
Provides attachment for ribs posteriorly
Transmits wt of trunk and upper body to lower extremities and is supported by hip bones

2

What is difference between spinal canal and cord

Canal-contains spinal cord and is filled with CSF begins at base of skull and extends into sacrum
Cord- enclosed/protected by spinal cord begins with medulla oblongata and tapers off at 1st lumbar vertebra.

3

Early life vertebra

Average of 33 with sacrum and coccyx not fused

4

Adult life vertebra

26 vertebrae, sacrum and coccyx are fused

5

What are the 5 divisions of the spine

Cervical-7
Thoracic-12
Lumbar-5
Sacrum-1 in adults 5 in children
coccyx- 1 in adults 3-5 in children

6

Cervical/lumbar curvature shape and type

concave posterior
lordotic curves

7

Throacic/sacral curvature shape and type

convex posterior
kyphotic curves

8

Primary Curves & example
(3)

Present at birth
thoracic and sacral curves are primary
convex posterior

9

Compensatory/secondary curves & example
(4)

Develop after birth
cervical and lumbar curves
are concave posterior
cervical is least pronounced curvature

10

When does a child begin to develop cervical curvature

when they begin to hold head up and try to sit up

11

When does a child begin to develop lumbar curvature

When they begin to walk

12

Lumbar curvature is more pronounced in

Females

13

Lordosis

an abnormal lumbar curvature with increased concavity
Lay term-sway back

14

Kyphosis

An abnormal thoracic curvature with increased convexity
Lay term-hump back

15

Scoliosis

an abnormal, lateral curvature of the spine

16

Typical vertebra consist of what 2 parts

body
vertebral arch

17

What makes up vertebral arch

Pedicles
laminae

18

What makes up foramen

the body and vertebral arch - stacked

19

What latin word means little foot

Pedicle

20

Where can spinous processes be palpated

neck and back

21

What are the articulating surfaces of articular processes

facets

22

Where is superior vertebral notch located

along the upper surface of each pedicle

23

Where is the inferior vertebral notch located

along the lower surface of each pedicle

24

What are intervertebral foramina formed by

superior and inferior verebral notches on each side
allow passage of nerves and blood vessels

25

What vertebra do not have intervertebral discs?

c1-2

26

2 parts of intervertebral disk

Annulus fibrosis
Nucleus pulposus

27

Apophyseal/zygapophyseal joints
Class
MT
Formed by

Diarthroidal
Gliding
Superior and inferior articular facets of adjacent vertebrae

28

Intervertebral joints
Class
MT
Formed by

Amphiarthroidal
none
in between bodies of vertebrae

29

When are lumbar intervertebral foramina demoed

TRUE lateral projection

30

What lumbar vertebra is slightly not 90 angle

L5, it's slightly anterior

31

What are 2 purposes of lumbar intervertebral foramina

passage of nerves and blood vessels

32

When are zygapophyseal joints demoed

oblique projections

33

How are zygapophyseal joints formed

superior and inferior articular facets of adjacent vertebra

34

Scotty dog Nose

Transverse Process

34

What angle do lumbar zygapophyseal joints form to MSP

30-lower
50-upper

35

Scotty Dog
Eye

Pedicle

36

Scotty Dog
Ear

Superior Articular Process

37

Scotty Dog
Neck

Pars Interarticularis

38

Scotty Dog
Front Paw

Inferior Articular Process

39

Scotty Dog
Body

Lamina

40

Scotty Dog
Tail

Opposite side superior Articular process

41

Scotty Dog
Hind Paw

Opposite Inferior Articular Process

42

Spondylolysis

Breakdown of pars Interarticularis
Will be demoed as a defect in neck of Scotty

43

Spondylolisthesis

Forward slippage of 1 vertebra or another

44

Spina bifida

Failure of 2 lamina to unite causing an opening where the spinous process is usually found

45

Herniated nucleus pulposus

Nucleus pulposus protrudes and presses on spinal cord & or spinal nerves
Usually results from injury

46

Laminectomy

Not a patho
Surgical removal of lamina
Laminae are weakest part of vertebrae
Easy fix for HNP

47

Compression Fracture

Superior and inferior surfaces of vertebral body driven together producing a wedge shaped vertebra
Causes osteoporosis, mets,trauma
Force needed to cause this injury may be minor
