2) Spinous processes
3) Inferior border of the scapula
4) Twelfth rib

Vertebra Prominens ✅1) Flex head and feel for most prominent bony spur at base of
neck (C7)
2) If two bony spurs are there, upper is C7 and lower is T1

Spinous Processes ✅1) Align with ribs down to T4
2) Then, angle downward

Inferior Border of the Scapula ✅1) Symmetric in each hemithorax
2) Lower tip at seventh or eighth rib

Twelfth Rib ✅Midway between spine and person's side to ID its free tip

Lateral Lobe ✅1) Extends from apex to 7th or 8th rib
2) Right upper lobe extends from apex of axilla down to horizontal fissure at 5th rib
3) Right middle lobe from horizontal fissure to down and forward to 6th rib at mid
clavicle
4) Right lower lobe: 5th-8th rib down midaxillary line
5) Left lung: two lobes, seen laterally as triangles separated by oblique fissure
6) Left upper (apex of axilla to 5th rib at midaxillary line
7) Left lower (down to 8th rib in midaxillary line)
