Resp

Question 1

Joints of chest wall& bones join

Answer 1

Costochondral- costal/rib
Sternocostal
Sternoclavicular
Sternal angle?

Question 2

Costal margin&subcostal define positios

Answer 2

Margin-lower border of the ribs

Subcostal- L3, below rib 10

Question 3

lung fissures and markings?
lung boundaries?
lobe marking differences?
parietal &visceral pleura markings?

Answer 3

oblique-join T3 to CC6
horisontal(R only)- CC4 follow rib to oblique at axillary

medial 3rd clavicle, sternoclavicular, CC 2,4,6, median, rib6 clavicular, rib8 axillary, rib 10 scapular/posterior median, T1 post median

horisontal-upper/middle
oblique-middle/lower(R) or upper/lower(L)
on L lung 6 CC 3cm lateral due to cardiac notch (and visceral but not parietal)

pleura same levels as lungs up to CC6(parasternal)
then
parietal- rib8 clavicular, rib 10 axillary, T12 scapular, L1 post median
visceral- rib 6 clavicular, rib 8 axillary, T12 scapular

Question 4

where do u parcuss/auscultate on chest, exception?

Answer 4

Intercostal space, percuss medial clavicle

Question 5

Describe & demonstrate the surface marking of mediastinal pleura of right & left lung on the anterior chest wall

Answer 5

Right: Parietal pleura projects above 1st costal cartilage, extends into neck above the medial 1/3rd of the clavicle. Runs down sternum to level of 6th costal cartilage.

Left: Parietal pleura projects above 1st costal cartilage, extends into neck above the medial 1/3rd of the clavicle. Runs down sternum to level of 4th costal cartilage. Deviates to left to allow for cardiac notch – 2-3cm.

Question 6

Describe & demonstrate the surface marking of the inferior margin of parietal pleura of right/left lung.

Answer 6

Right: Transverse process of T1 vertebrae, around root of neck, parietal pleura projects above 1st costal cartilage, extends into neck above the medial 1/3rd of the clavicle. Runs down sternum to level of 6th costal cartilage. Reflects onto the diaphragm above costal margin, goes around the thoracic wall following rib 8 (midclavicular line), rib 10 (midaxillary line), rib 12 (T12), transverse process of L1 vertebra.
