Spinal Biomechanics- Lecture 9 Vertebral Column

Front 1

V Column built for

Back 1

mobility stability and protection

Front 2

23 discs IVDs what typer of joints?

Back 2

cartilaginous symphysis joints (annulus, nucleus, end plates)

Front 3

facet joints are..

Back 3

z joint, apophyseal
diarthrodial (synovial joints)

Front 4

Kinematics

Back 4

kinematics

Front 5

general motions are?

Back 5

flex, extension, rotation, lateral flexing/bending

Front 6

Coupled motion (coupling)

Back 6

the consistent association of one motion about an axis with another motion about a different axis. Most predominant are rotation & lateral flexion – in order for either to occur some of the other must also occur

Front 7

the _________ of motion available is determined primarily by the relative size of the _____?

Back 7

1.amount
2.disc

Front 8

the________ is determined primarily by the orientation of the _________

Back 8

direction of motion

facets

Front 9

Facet joint capsule provide stability while limiting motion
C/S - restricts?
T/S little effect on?
L/S- restraint?

Back 9

1. rotation and lateral bending
2. ROM due to other structures
3. rotation and flexion

Front 10

Capsules are thickest at the ?

Back 10

C/T and T/L junctions- areas of curvechanges and increased stress

Front 11

Kinetics

Back 11

kinetics

Front 12

Compression

Back 12

results of gravity, ground reaction forces, the pull of ligaments and muscles

Front 13

Tensile

Back 13

result from resisting motion

Front 14

Bending

Back 14

results in compression and tension

Front 15

torsion

Back 15

created by rotation

Front 16

Shear

Back 16

result of translating during flexion/extension and lateral bending
