Morphological traits of similarity in phylogenetically distant primate species

Abstract

The author describes the variability in the formation of some internal organs in primates viz. the lenght of the supradiaphragmatic portion of the inferior vena cava; the angle between heart long axis and the axis of the sternum; the position of the tip of the heart; the course of the terminal parts of the pulmonary veins; the shape of the thyroid; the formation of the renal medulla; the form of the palatal uvula; the shape of the sympathetic trunk.
