You say , "...we say the origin of the [external intercostal] is the rib above...the insertion is pulled towards the origin...if the muscle were to contract it would pull this [lower] rib upward..." However, this doesn't really explain anything. Why doesn't the external intercostal (EI) pull the upper rib down? I've tried to find a biomechanical mechanism for why the external intercostals pull the ribs up, and it is very hard to find. The best explanation I could find is that the attachment of the EI to the upper rib is closer to the costovertebral joint, therefore the EI muscle has less leverage on the upper rib, and conversely more leverage, or a larger moment arm on the lower rib. The force on the two ribs is equal and opposite, but the greater moment arm on the lower rib means it moves up.
I know I'm too late.. I think understanding myosin and actin, those are responsible for muscles contraction, can answer your question.
Where did you take the figures from?
I have a question: how all this information is being stored inside a single cell?
👍👍👍
I thought the Innermost intercostal muscle isn't replaced by a membrane??
yeah me too, I tried to find sources that mentioned it but I couldn't.
the origin insertion and action of internal intercostal muscle has been taught wrong. it's actually the opposite of what's been told.
Can you please explain?
Thank you
