Witryna24 paź 2024 · Avian musculoskeletal adaptations for flight. (A) The forelimb, shoulder and trunk skeleton of birds underwent several substantial evolutionary modifications to facilitate an effective flapping wing stroke powered by large flight muscles: the main downstroke pectoralis muscle (light red), and the main upstroke supracoracoideus … WitrynaStudies of medium- and large-bodied avian species have suggested that variation in flight muscle composition is related to differences in flight behavior. ... (85.5% FOG, 14.5% SO), which may reflect the reduced role of the hindlimb during take-off. We further hypothesize that thermogenic requirements constrain fiber type heterogeneity in these ...
