The characteristics of the muscle internal parameters of ape and human are discussed in comparison with those of monkey. Chimpanzees are great apes found across central and West Africa. Moreover, monkeys have larger normalized MM values for the elbow extensor muscles than apes, which may be attributed to the fact that almost all monkeys engage in quadrupedal locomotion. knuckle-walking in chimpanzees and brachiation in gibbons, and the different frequencies of arm-raising locomotion between these two species. The results show that the different ratios of forearm-rotation muscles between chimpanzee and gibbons may be related to the differences in their main positional behaviour, i.e. Moreover, individual normalized data were compared directly amongst species, independent of size differences. The Human Evolution Coloring Book provides a useful illustration of the Comparative Anatomy of Chimpanzees and Humans. The MM distributions and the percentages in terms of functional categories were calculated as the ratios of the muscle masses. The recent chimpanzee attack has raised the issue of how strong chimpanzees really are a question that lacks a solid answer, since chimps rarely compete in either Olympic-style weightlifting or powerlifting.
muscle mass (MM), muscle fascicle length and muscle physiological cross-sectional area (an indicator of the force capacity of muscles), was conducted in nine primate species: human (Homo sapiens), chimpanzee (Pan troglodytes), gibbon (Hylobates spp.), papio (Papio hamadryas), lutong (Trachypithecus francoisi), green monkey (Chlorocebus aethiops), macaque monkey (Macaca spp.), capuchin monkey (Cebus albifrons) and squirrel monkey (Saimiri sciureus). A comparative study of myological morphology, i.e.
