: Can you elaborate on bucket handle and pump handle breathing?
Please take a look at previous essay answer guides for mechanics of breathing.
pump handle - sternum, upper 7 ribs, Ant/Post diameter
bucket handle - costal margin, ribs 8-10, transverse diameter
Vertical expansion - diaphragm
A key observation is the shape of the costotransverse joints
upper ribs - cupped
lower ribs - planar
Joints involved
costovertebral
costotransverse
costochondral
sternochondral
Muscles involved - have something to say but this is open.
