RESPIRATORY Flashcards
What are the identifying features of the thoracic vertebrae?
2 pairs of demi facets
- Superior costal facet articulates with head of rib of the same number
- Inferior costal facet articulates with head of rib below
Transverse processes have an additional facet = transverse costal facet which articulates with tubercle of rib of same number
Body of tharacic vertebrae typically heart shaped
Vertebral foramen typically circular
Name the 3 parts of the sternum and their corresponding vertebral levels.
Manubrium - T2/3- T4/5
Body - T5-8
Xiphoid process - T8/9
Describe the true and false ribs and where they articulate
R1-7 = true ribs
- articulate anteriorly with sternum via costal cartilages
R8-12 = false ribs
- R8 - 10 articulate anteriorly with the costal cartilage of the rib above
- R11 + 12 = floating - no anterior articulation, posteriorly articulate with bodies of their own vertbrae
vertebral level of subcostal plane
Level of L3
plane passing through lowest margin of the ribs
Surface mark the upper lobe of the right lung
apex - 2-3cm above medial 3rd of clav
sternoclavicular joint –> right 2nd CC –> 4th right CC –> T3 just lateral to PML –> T1 just lateral to PML
surface mark the middle lobe of the right lung
4th right CC –> 6th right CC –> 6th rib at MCL –> 4th rib at MAL (where oblique fissure meets horizontal fissure)
surface mark the lower lobe of the right lung
6th right CC –> 6th rib at MCL –> 8th rib MAL –> 10th rib just lateral to PML
surface mark the upper lobe of the left lung
apex 2-3cm above clav –> left 2nd CC –> 4th CC –> 6th CC –> T3 –> T1
surface mark the lower lobe of the left lung
6th left rib at MCL –> 8th rib at MAL –> 10th rib lateral to PML
demonstrate the oblique fissure in both lungs
palpate T3 (scapular spine) and 6th CC anteriorly - then connect the two points
demonstrate the transverse fissure of the right lung
palpate 4th CC anteriorly –> trace along 4th rib until it meets oblique fissure at MAL near axilla (no posterior surface markings)
surface mark the right parietal pleura
apex = 2-3cm above clav –> 6th CC at sternal border –> 8th rib at MCL –> 10th rib at MAL –> T12 at scapular line
surface mark the left parietal pleura
apex = 2-3cm above clav –> defelect left between 4th and 6th CC –> 6th CC at sternal border –> 8th rib at MCL –> 10th rib at MAL –> T12 at scapular line
surface mark the right visceral pleura
apex = 2-3cm above clav –> 6th CC at sternal border –> 6th rib at MCL –> 8th rib at MAL –> T10 at scapular line
surface mark the left visceral pleura
apex = 2-3cm above clav –> defelect left between 4th and 6th CC –> 6th CC at sternal border –> 6th rib at MCL –> 8th rib at MAL –> T10 at scapular line
