a) the diaphragm F-
b) internal oblique T
c) external oblique F
d) scaleus anterior F
e) the trapezius F
Inspiratory muscles- Diaphragm, ext oblique, scalene, trapezius, SKM.
Expiratory muscles- Abdominal, internal oblique.

Internal and external oblique are ABDOMINAL muscles.
Internal and external INTERCOSTALS are between the ribs.
I thought diaphragm, ext INTERCOSTALS, scalenes and sternocleidomastoid were used for inspiration.
Expiration is abdominal muscles (presumably then int and ext oblique) and int INTERCOSTALS.
