these are the muscles between your ribs, human ribs maybe not so good but beef ribs witha nice bbq sauce- outstanding. those are the muscles you are chowing down on when you are filling your face at tony roma's.
there are 2 sets of intercostals, internal and external, pretty self explainatory,they are layered one on top of the other.
their function are-the external intercostals- to draw the rib cage up to increase thoracic volume ( take a deep breath) and the internal intercostals-draw the ribs down (exhale) and also to hurt like hell when you pull either one.
thank you, please come again
