Estimates of the bending moments exerted by the lumbar and abdominal muscles of some mammals

Authors


Abstract

The abdominal and lumbar muscles of rat, ferret, dog and hare have been measured and their arrangement noted. Rough calculations have been made of the flexor or extensor moment each muscle can exert, about a mid-lumbar intervertebral joint. Comparisons are made with previously published data on man.
