Surface marking of lungs

Question 1

Describe the posterior surface markings of the lungs

Answer 1

Continue 2.5 cm above the clavicle

Descend posteriorly 2cm either side of spinous prcoesses

Come across the 10th rib horizontally and join the lungs at the mid-axillary line

Question 2

Pleura

Answer 2

Follow same surface marking at the lungs apart from inferiorly

At the mid axillary line at the 10th rib and posteriorly at the 12th rib.

Question 3

Oblique fissure

Answer 3

can be drawn from spinous process at t3 down and laterally

Follows the line of medial border of scapula and to the 5th rib at the mid axillary line.

Get patient to abduct to get the medial border

Continues to 6th costal cartilage anteriorly

Question 4

Middle lobe (female)

Answer 4

Horizontal fissue begins in mid axillary line in the 5th rib

Horizontal line that goes across following the 4th rib to the 4th costal cartilage

Differentiating the lung between the upper lobe, middle lobe and the lower lobe

Producing a wedge like segment through the lung

Question 5

Middle lobe (male)

Answer 5

5th rib at mid axillary line

Goes across horizontally to the 4th costal cartilage

Gives us middle lobe of the right lung

Question 6

Anterior surface markings of the lungs

Answer 6

Start 2.5 cm above the medial 3rd of the clavicle

Descend behind the manubrium sternal notch

Left one comes down to thte 4th costal cartilgae

Then laterally to 6th costal cartilage at the mid clavicular line

Then 8th rib at mid axillary line

R-
6th CC, 6th rib, 8th rib at mid axillary line
