Study These Flashcards
A

Radiate ligament

25
Costotransverse joint members include?
Nick of rib w/facet ant aspect of TP
26
Costotransverse joint classification?
Synovial, Planar
27
Ligamentous support of Costotransverse joint?
Costotransverse ligament
28
Costochondral joint classification
Synarhrroses and Synchondrosis
29
1st chondrosternal joint
B/n 1st rib costal cartilage and manubrium is synarthrodial joint.
30
2nd chondrosternal joint is a
Diarthrodial (synovial) joint
31
3rd-7 Chondrolsternal joints classification?
Synovial, Planar
32
Interchondral joints location
Ribs 6-10
33
Interchondral Joints classification?
Synovial
34
Manubristernal Joint classification
Symphysis ( joint w/fibrocartilaginous disc)
35
Xiphisternal joint classification
Symphysis
36
Diaphragm movement
As diaphragm contracts height decreases, increasing volume of thorax. Connected by central tendon
37
External Intercostal Muscle superior layer fiber direction
Hands in pocket
38
Internal intercostal muscles fiber direction
Inferolateral
39
Limiting factor forward bending
facets upglide bilaterally | Annulus fibrosus compresses anteriorly
40
Limiting factor backward bending
facets downglide bilaterally Ant annulus fibrosus stretched firm and possible bony end feel
41
SB non-functional
``` SB and rotation are opposite ipsilateral facet glides inferiorly contralateral facet glides superiorly vertebra rotates contra laterally Ipsilateral disc compressed ```
42
SB functional
SB and rotation same side Ipsilateral facets gap Contralateral facets compress
43
Rotation
Ipsilateral facets gap Contralteral facets compress Minimal rotation in segments but great rotation as a whole
44
Conduit
structures that pass completely through the thorax from one body region to another or structures that connect organs in the thorax to other body regions.
45
Upper thoracic region
T1-T4
46
middle thoracic region
T4-T9
47
Lower thoracic region
T10-T12
48
TP typical characteristics
articulate with turbercle of the rib to form the joint of the head of rib.
49
4 articular processes on each vertebrae
2 superior and 2 inferior articular processes
50
Atypical Rib 1
Single articular facet on head of rib, most highly curved rib.
51
Atypical rib 10
Head of the 10th rib contains only one articular facet for articulation with the body of the 10th thoracic vertebra.
52
Atypical ribs 11 and 12
Heads only contain one articular facet to articulate with vertebra. These ribs do not contain necks, tubercles, or rib angles
53
3 layers of intercostal muscles superficial to deep
External Intercostal Internal Intercostal Innermost Intercostal
54
Extension Biomechanics and limiting factors
ALL, Rectus abdominus, facets downglide, posterior compression, sagittal plane, frontal axis.
55
Flexion biomechanics and limiting factors
Supraspinus, interspinus, PLL, ligamentum flavum, intertransverse ligaments. Anterior compression Erector spinae limits
56
Facet movement when in neutral
SB contralateral rotation
57
Facet movement when in functional position
Ipsilateral opening of facets and contralateral closing.
58
SB limitation
Quadratus lumborum, inter transverse, iliolumbar ligaments | Facets open contralateral side
