what bony features form the thoracic inlet and outlet
First Rib
musculature
- external intercostals
- internal intercostals
- innermost intercostals
- subcostals
- transverse thoracis
external intercostals
internal intercostals
innermost intercostals
subcostals
transverse thoracis
external intercostals function
inhalation (moves the ribs superiorly)
internal intercostals function
exhalation (moves the ribs inferiorly
innermost intercostals function
acts with internal intercostal
subcostals function
pulling the ribs inferiorly during forced exhalation
transverse thoracis function
depresses the ribs which supports expiration
