In forced inspiration:
• Scalenus anterior and medius elevate the first rib.
• Sternocleidomastoid acts directly through the manubrium
sterni and indirectly through the clavicle.
• The scapulae are fixed by the trapezius, levator scapulae and
rhomboid muscles which enable the serratus anterior and
pectoralis minor to pull up the ribs.
• Quadratus lumborum fixes the 12th rib so that the diaphragm
can exert a more powerful downward push on the abdominal
viscera.

▪ Bronchus:
➢Lies in the ,,,,,,,,part of the hilum.
➢It can be identified by the presence of cartilagenous rings in its wall.
➢The,,,,,,,,,,,,,, bronchus divides before entering into the lung into upper
branch (eparterial bronchus) and lower branch (hyparterial
bronchus).
➢The bronchus divides after entering into the lung, so only a single
bronchus is present in the hilum.
