24
Q

Which ribs are involved with sternocostal joints? Are all these joints the same - what can you see on the sternum that backs this up?
(hint: think classification)

A

Ribs 1-7 are involved with sternocostal joints.

Sternocostal joint 1: cartilagenous, synchondrosis, slight move. This is observable as the first costal notch is rough.

Sternocostal joints 2-7: synovial, uniaxial, gliding. This is observable as the costal notches posses facets.

25
Q

Presence of facets indicates what? (general answer)

A

Facets indicate movement (therefor synovial articulation).

26
Q

Name the ligaments that support the sternocostal joints.

A

Radiate sternocostal ligaments - all.

Intra-articular ligament - rib 2.

27
Q

What is unique about the 2nd sternocostal joint?

A

It possesses 2 articular facets (superior and inferior), which are separated by an intra-articular ligament. Both facets are located within the same capsule (composite joint), and are individually, and collectively recognised as synovial, uniaxial, gliding.

28
Q

How are interchondral joints numbered?

A

Via the intercostal space in which they reside.

29
Q

Which number ribs are involved with interchondral joints?

A

Ribs 5-10 possess interchondral ligaments.

30
Q

Name the ligaments that support the interchondral joints.

A

Interchondral ligaments.

31
Q

Name and briefly describe the 2 parts of the IV disc.

A
  1. Annulis fibrosis (outer) - collagen fibres; fibrocartilage.
  2. Nucleus pulposis (inner) - mucoproteins; soft.

(note: NP is remnant of notocord).

32
Q

Explain the variation in costovertebral joints.

A

2 joints in 1 capsule: 2 - 9, possibly 10. Separated by intra-articular ligament.
1 joint in 1 capsule: 1, 11, 12, possibly 10.

33
Q

Detail the difference in surfaces of tubercles for groups of ribs below, including the functional consequence.

a. ) Ribs 1 - 6
b. ) Ribs 7 - 10

A

a. ) Ribs 1 - 6: facets on tubercles convex; rotation of rib traslated to elevation or depression at sternal end. Increase ANT/ POST dimensions.
b. ) Ribs 7 - 10: facets on tubercles flatter; permits gliding resulting in elevation or depression of lateral portion of ribs. Increase lateral dimensions.

34
Q

State the general roles of ligaments. (2)

A
  1. Structural support.

2. Proprioception.

35
Q

State the specialised role of ligaments. (1)

A

Limit or permit movement in particular fashion.

36
Q

What types of joints require ligamentous support?

A

Joints where movement occurs; synovial.

37
Q

State the attachment points for the following ligament:

Radiate costovertebral ligament.

A

Head of rib to vertebral body.

38
Q

State the attachment points for the following ligament:

Intra-articular ligament (of costovertebral joint).

A

Crest of head of rib to IV disc.

39
Q

State the attachment points for the following ligament:

Superior costotransverse ligament.

A

Crest of neck of rib to TVP of vertebrae above.

40
Q

State the attachment points for the following ligament:

Lateral costotransverse ligament.

A

Non-articular part of tubercle of rib to tip of TVP.

41
Q

State the attachment points for the following ligament:
Costotransverse ligament.
(yes - this is it’s whole name).

A

Posterior neck of rib to TVP of matching vertebrae.

42
Q

State the attachment points for the following ligament:

Anterior longitudinal ligament.

A

Anterior edge of foramen magnum to pelvic surface of sacrum.
(note: also attaches to anterior tubercle of C1).

43
Q

State the attachment points for the following ligament:

Posterior longitudinal ligament.

A

Posterior body C2 to the sacral canal.

note: runs inside vertebral canal

44
Q 
State the attachment points for the following ligament:
Ligamentum flavum (interlaminal ligament).
A

Between laminae, begins between C2 and C3 and occurs all the way down until sacrum.

45
Q

State the attachment points for the following ligament:

Interspinous ligament.

A

Between adjacent spinous processes.

46
Q

State the attachment points for the following ligament:

Supraspinous ligament.

A

Between tips of spinous processes only; from C7 to sacrum.

47
Q

State the attachment points for the following ligament:

Nuchal ligament.

A

Posterior to spinous processes, from C7 to external occipital protruberance.

48
Q

State the attachment points for the following ligament:

Intertransverse ligament.

A

Between adjacent TVP.

note: varies with level

49
Q

State the attachment points for the following ligament:

Anterior atlanto-occipital membrane.

A

Anterior foramen magnum to anterior arch of C1.

50
Q

State the attachment points for the following ligament:

Posterior atlanto-occipital membrane.

A

Posterior foramen magnum to posterior arch of C1.

51
Q

State the attachment points for the following ligament:

Anterior atlanto-axial membrane.

A

Anterior arch of C1 to body of C2.

52
Q

State the attachment points for the following ligament:

Posterior atlanto-axial membrane.

A

Posterior arch of C1 to neural arch of C2.

53
Q

Why are some ligaments referred to instead as membranes?

A

Membranes are thinner, flatter and weaker sheets of CT. These exist as more movement is needed in those regions.

54
Q

State the attachment points for the following ligament:

Tectorial membrane.

A

Posterior body C2 to floor of cranial cavity.

55
Q

State the attachment points for the following ligament:

Cruciate ligament.

A

Cruciate ligament has 3 parts:

  1. Superior
  2. Transverse - attaches to small tubercles of C1.
  3. Inferior.
    (note: cruciate is deep to tectorial membrane)
