Ribs Flashcards
Rib attachments?
Attaches to superior costal facet of same number and inferior costal facet of above vertebra
What is costal tubercle?
Where rib articulates with the TP of the vertebra
What is costal angle significance>
Where you palpate rib posteriorly to look for SD
What ribs only articulate with their own vertebra, and not the one above?
Rib 1, 10, 11, 12
What are atypical ribs?
1, 2, 11, 12
What are true ribs?
1-7, they attach to the costal cartilage
What are false ribs?
8-10 they attach to costal cartilage of the rib above
What are floating ribs?
11 and 12 and they have no attachment
Where is sternal angle?
rib 2
Where does anterior and middle scalene insert?
Superior surface of 1st rib to elevate first rib
Where does posterior scalene insert?
2nd rib
Where does pec minor attach?
Anterior superior surface of ribs 3-5
Where does serratus anterior attach?
superior lateral surface of ribs 2-8
Where does latissimus dorsi attach?
Lower 4 ribs
Where does quadratus lumborum attach?
Inferior aspect of rib 12
Where does the neuro bundle run and what order?
VAN found between internal intercostal and innermost intercostal running along the costal groove on inferior side of rib
Bucket handle motion?
moves superiorly and laterally to increase transverse diameter of ribs 1-2, 8-10
What is pump handle motion?
Move superiorly and anteriorly to increase AP diameter, ribs 3-7
What is caliper or pincer motion?
Downward and posterior with inhalation Upward and superior with exhalation Ribs 11 and 12
What is torsional movement?
For example when T5 is rotated to left on T6
Left 6th rib:
- posterior aspect turns externally
- anterior extremity more flat with its inferior border sharp
Right 6th rib:
- posterior aspect of rib turns internally
- Anterior extremity having its superior margin excenuated
what causes torsional motion?
caused by articulation at inferior costal facet
Anteior subluxationn?
Both posterior and anterior parts of ribs are moved anterior
Posterior subluxation?
Anterior and posterior parts of rib move posteriorly
Examples of respiratory SD?
- Bucket handle ribs 1 & 2 & 8-10
- Pump handle 3-7
- Caliper 11-12
