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

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
Intrinsic Spinal Ligaments
Ligamentum Flavum Interspinous
26
Superifical Back Muscles
Lat Dorsi Trapezius Levator Scapulae Rhomboids
27
Intermediate Back Muscles
Serratus Posterior Sup/Inf (help with resp)
28
Deep Back Muscles
Iliocostalis Longissimus Spinalis Multifidus
29
Erector Spine Muscle Function
Connects lower spine to upper spine
30
Erector Spine Muscles
Longissimus Spinalis Iliocostalis
31
Multifidus Muscle
Connects transverse process to vertebral higher up
32
Why do lower vertebrae have less movement potential
Facets superior posterior
33
Why do upper vertebrae have high movement potential
Facets anterior inferior
