The sixth rib anteriorly and the eighth rib laterally
Rest on the diaphragm at the fifth intercostal space in the midclavicular line (MCL)
Extend 3 to 4 cm above the inner third of the clavicles
The level of the second rib anteriorly
The Correct Answer is C
A. The sixth rib anteriorly and the eighth rib laterally:
Describes the borders of the bases of the lungs, not the apices.
B. Rest on the diaphragm at the fifth intercostal space in the midclavicular line (MCL):
Also refers to the base of the lung, not the apex.
C. Extend 3 to 4 cm above the inner third of the clavicles:
This is the correct anatomical landmark for the apices of the lungs.
D. The level of the second rib anteriorly:
Marks the angle of Louis (sternal angle), a reference point for rib counting-not the lung apices.
