Q

Articular Process Attach

A

Next vertebrae

17
Q

Pedicles are found

A

Between vertebral body and transverse processes

18
Q

Laminae are found

A

Between transverse processes and spinous process

19
Q

Annulus Fibrosis is fibrous/fluid

A

Fibrous (collagenous)

20
Q

Nucleus Pulposus is fibrous/fluid

A

Fluid

21
Q

Why do we get shorter with age

A

Nucleus Pulposus gets stiffer and compressed over time resulting in vertebrae being closer together = shorter

22
Q

Vertebral Herniation is

A

Bulging of nucleus Pulposus = compresses spinal nerve

23
Q

Most common vertebrae to have a hernia

A

Lumbar as posteriorly angled

24
Q

Continous Spinal Ligametns

A

Anteiror Longitudinal
Posterior Longitudinal
Supraspinous

25
Q

Intrinsic Spinal Ligaments

A

Ligamentum Flavum
Interspinous

26

A

Iliocostalis
Longissimus
Spinalis
Multifidus

29
Q

Erector Spine Muscle Function

A

Connects lower spine to upper spine

30
Q

Erector Spine Muscles

A

Longissimus
Spinalis
Iliocostalis

31
Q

Multifidus Muscle

A

Connects transverse process to vertebral higher up

32
Q

Why do lower vertebrae have less movement potential

A

33
Q

Why do upper vertebrae have high movement potential

A

Facets anterior inferior
