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.
