Joint function in marmosets and tamarins: Insights from computational modeling of hip extensor muscles.

ABSTRACT: Analyses of the musculoskeletal system of callitrichid primates contribute to the understanding of the specializations of an apparently highly conserved body plan exhibited by this radiation of New World primates. This pilot study provides data from computational modeling of muscle function of five hip extensor muscles in four species of Callitrichidae to identify potential adaptations to previously documented differential leaping behaviors. Based on microCT scans of fresh cadavers, we reconstructed the muscle topology to inform the modeling of instantaneous muscle moment arms (MMAs) contributing to hip extension and accompanying muscle strains. Generally, muscle properties of the four species were surprisingly similar despite documented differences in leaping behavior. However, all extens
