37
Muscles of relaxed expiration
No muscles involved d/t elastic recoil of lungs and thorax
38
Muscles of forced expiration
Abdominals Serratus Posterior Inferior Internal intercostals
39
A forward and upward movement of the sternum and upper ribs
Pump-handle motion
40
Pump-Handle motion increases what dimension?
Antero-posterior dimension
41
What happens to the thoracic spine during pump-handle motion?
Thoracic spine extends to enable greater excursion of the sternum
42
In what ribs does the pump-handle motion occur?
Ribs 1-7
43
An elevation and outward turning of the lateral portion of the ribs
Bucket-Handle motion
44
What dimension does the Bucket-Handle motion increase?
Transverse (lateral) dimension
45
In what ribs does the Bucket-Handle motion occur?
Ribs 8-10
46
An increase in the subcostal angle
Caliper motion
47
What happens to the rib segments during caliper motion?
The costochondral junction also increases, making the rib segments longer during inspiration
48
An increase in the vertical dimension
Piston action
49
What happens to the diaphragm during piston action?
The central tendon of the diaphragm descends as the muscle contracts.
50
How does the vertical dimension increase in piston action?
Elevation of the ribs increases vertical dimension of the thorax. It also improves the effectiveness of the diaphragm
51
What structures of the brain controls the breathing?
Medulla Oblongata Pons
52
Respiratory group that controls the normal quiet breathing

62
Involves the exchange of air between the atmosphere and the alveoli of the lungs
