1
Q
which muscles are involved in quiet inspiration
A
- external intercostals
- scalene muscles
- diaphragm
2
Q
which muscles are involved in quiet expiration
A
- it is a passive process
- happens due to elastic recoil of lungs
- and relaxation of inspiratory muscles
3
Q
which muscles are used in forced inspiration
A
- external intercostals
- scalene muscles
- diaphragm
- pectorals
- sternocleidomastoid
- latissimus dorsi
4
Q
which muscles are used in forced expiration
A
- internal intercostals
- oblique and transverse abdominals
- quadratus lumborum
5
Q
insertion of the diaphragm
A
central tendon
6
Q
origin of the diaphragm
A
sternal - xiphoid process costal - costal cartilages of ribs 7-10 - ribs 11 and 12 lumbar - medial and lateral arcuate ligaments - lumbar vertebral bodies
7
Q
what are the openings of the diaphragm and where are they
A
- opening for inferior vena cava: T8
- oesophageal hiatus: T10
- aortic hiatus: T12
8
Q
what is the blood supply of the diaphragm
A
superior and inferior phrenic arteries
9
Q
what does the phrenic nerve provide motor innervation to
A
diaphragm
10
Q
what does the phrenic nerve provide sensory innervation to
A
