Q

Pubic symphysys

A

Fibrocartilaginous joint, completes pelvis ring for pelvis stability.

21
Q

In what direction do S1 superior articular facets face?

A

Posteriorly

22
Q

Ant Longitudinal Ligament

A

Covers ant surface of vert bodies from C2 to sacrum. Broadest in lumbar, tapers superiorly.

23
Q

Post Longitundinal Ligament

A

Cover post vert bodies, C2-sacrum. Thinner in Lumbar, widest cervically

24
Q

Ligamentum Flavum

A

Posterior, connects adjacent Laminae

25
Q

Interspinous ligament

A

Connects adjacent SPs

26
Q

Supraspinous ligament

A

Long post ligament, overlies all SPs

27
Q

Which side of the spine has the strongest ligamentous support?

A

Posterior > anterior

28
Q

Iliolumbar ligament

A

L4-5 TP’s to iliac crest

29
Q

SI joint ligaments (ant & post)

A

oriented horizontally & vertically. Play major role in pelvic stability.

30
Q

Sacrotuberous ligament

A

From posterior sacrum to ischial tuberosity

31
Q

Sacrospinous ligament

A

From sacrum to ischial spine

32
Q

How many layers does the Thoracolumbar Fascia have?

A

3, superficial, intermediate, and deep

33
Q

Functions of TLF

A

Part of attachments for Trans Abd, Latis Dorsi, Glut Max. Assist with spinal stability

34
Q

Erector Spinae

A

Intermed layer, primarily spinal extensors, respond to external loads.

35
Q

Transversospinalis

A

Deep layer. As a group, inherent stabilization of spine, postural stability.

36
Q

How does QL help maintain posure?

A

Resists hip drop forces in SL stance and gait.

37
Q

How is Trans Abd though to help stabilize spine?

A

Either increasing intra-abd pressure, or creating rigid cylinder around spine

38
Q

Ext/Int Obliques

A

Work with RA to counteract ant shear and tighten TLF

39
Q

Rectus Abd

A

Checks ant shear in lumbopelvis area.

40
Q

What will B tight HF’s do to pelvis?

A

Bring it into Ant Pelvic Tilt

41
Q

Which muscle controls pelvis in the Frontal Plane?

A

Glut Med

42
Q

What can a tight TFL/ITB do to pelvis?

A

Create anterior torsion force via attachments to Ilium.

43
Q

What will tight Hamstrings do to pelvis?

A

Force it into PPT

44
Q

Which portions of the IV Disc are innervated?

A

Only outermost portions of annulus. Inner layers and nucleus not innervated.

45
Q

Sinu-vertebral nerves

A

Branch off spinal nerves, & course back through IV formamen. Innervate ≥ 2 discs and Ant Long Lig.

46
Q

Which areas of spine have pain innervation?

A

ALL, PLL, Vert Body, Facet Jnt capsule & synovium, & nerve roots

47
Q

Which spine areas DON’T have pain innervation?

A

IV disc, except for outermost layer of annulus

48
Q

How does disc get blood supply?

A

No real supply of its own. Nourished by small capillary beds in subchondral bone of vertebral body.
