Differences among the forelimb arteries in groups of primates and a mathematical model explanation

Background Recently, some studies about primates have claimed the importance of the vessels to maintain the muscles working; in fact, the arterial supply could suggest how strenuous the muscular performance is associated to locomotor behavior. The aim of this work was to study the anatomy of the arteries of the forelimbs of different groups of primates to evidence a general arterial model in comparative terms. Methods We propose a biophysical explanation for the arterial pattern of the forelimbs of primates' groups. Results Three pattern of the forelimb arteries in Primates were descript and the differences were explained using mathematical formulas. Conclusions The anatomical study about the comparative anatomy of the arteries of the forelimbs of primates provided hypothesis about the three observed models, mainly in relation to brachial artery division and the number of the palmar arches, in mathematical models' terms.

Automated summary

This study examined the arterial anatomy of the forelimbs of different primate groups, presenting a general arterial model in comparative terms. Mathematical formulas were used to explain the differences in the observed arterial patterns, particularly in relation to brachial artery division and the number of palmar arches. The findings provided hypotheses about the three observed models in terms of mathematical models.
