Answer 4

under rib 1-6

Question 5

what are the surface markings of the left lower lobe

Answer 5

under rib 5-7

Question 6

describe the surface markings of the horizontal fissure

Answer 6

on the right lung

from the 4th costal cartilage following the 4th rib on the right to meet the oblique fissure in the mid axillary line

Question 7

describe the surface markings of the oblique fissure

Answer 7

from lung border at level of T3 posteriorly to lower border of lung at 6th costal cartilage anteriorly
runs around the lateral thoracic wall

closely follows medial border of scapula when arm is raised

Question 8

describe the surface markings of the parietal pleura of the right lung

Answer 8

apex is in the root of the neck above the medial 1/3 of the clavicle
just right of midline from 2nd CC to 6th CC
MCL at level of 8th rib
MAL at level of 10th rib
scapular line crossing 12th rib
transverse process of T1 vertebra

Question 9

describe the surface markings of the parietal pleura of the left lung

Answer 9

apex is in the root of the neck above the medial 1/3 of the clavicle
just left of midline from 2nd CC to 4th CC
deviates left to allow for cardiac notch
MCL at level of 8th rib
MAL at level of 10th rib
scapular line crossing 12th rib
transverse process of L1 vertebra

Question 10

what are the surface markings of the inferior margin of the visceral pleura

Answer 10

6th rib at MCL
8th rib at MAL
10th rib at scapular line

covers the lung so is the same as lung borders

Question 11

what are the borders of the triangle of safety

Answer 11

posterior: anterior margin of latissimus dorsi
anterior: posterior border of pectoralis major
inferior: 4th ICS
apex: below the axilla

Question 12

what are the surface markings of the left mediastinal pleura

Answer 12

mediastinal pleura = parietal pleura in mediastinum

projects just above 1st CC, extends into neck above medial 1/3rd of clavicle

runs down sternum to level of 4th CC, deviates left by 2-3cm to allow for cardiac notch

Question 13

what are the surface markings of the right mediastinal pleura

Answer 13

mediastinal pleura = parietal pleura in mediastinum

projects just above 1st CC, extends into neck above medial 1/3rd of clavicle

runs down sternum to level of 6th CC
