The authors translated into Portuguese and English the basic anatomical terminology used by the Yanomani indians. The knowledge of the names of organs and other parts of the human body and of a few having a clinical meaning should help those interested in the study of and in interaction with the Yanomanis.

The relationship between the papillary muscles and the anatomicosurgical segments of the left ventricle of the human heart.

The relationship between the blood supply of the papillary muscles of the left ventricle of 90 adult human Caucasian hearts and the arteries of the cardiac anatomicosurgical segments was studied after arterial injection of Vinyl acetate and partial or total corrosion. The anterior papillary muscle belongs in most cases to the I SV segment whereas the posterior muscle belongs to the III DV segment, the former pertaining to the left coronary a. and the latter to the right a.

[Critical analysis of the clinical and surgical importance of the variations in the origin of the sinoatrial node artery of the human heart].

There are several clinical controversies derived from the discrepancy on the description and relations of the coronary arteries in human hearts of either sex and in different races. OBJECTIVE--To study the clinical and surgical importance of the variations of the origin of the artery of the sinoatrial node in hearts of human individuals. MATERIAL AND METHOD--Normal hearts of cadavers of 100 individuals (31 females and 69 males), belonging to 24 Caucasians (whites) and 36 non-Caucasians (Negroes and Mulattoes), whose age varied ranged from 7 to 80 years, were studied. The coronary arteries were injected with gelatin mixed to a radiopaque substance (Cylatrast) and a red or blue pigment. RESULTS AND CONCLUSIONS--1) The artery of the sinoatrial node was originated more frequently from the right coronary artery (58%) than from the left. 2) When originated from the left coronary artery the artery of the sinoatrial node was more frequently a branch of the circumflex artery (30%) than from the trunk of the artery (12%). 3) No sexual or racial factor influenced the anatomical variations. 4) The most frequent arteries originating the artery of the sinoatrial node were the right anterior medial atrial artery and the left anterior medial atrial artery. 5) No cases of blood supply to the sinoatrial node were found originating neither from other arteries than the coronary arteries nor from both coronary arteries. 6) The distribution of the coronary arteries allows to understand the possible ischemic etiology of the sinusal node syndrome and permits to the surgeon a safe approach to cardiac disease.

[Clinical and surgical importance of anatomosurgical segments and subsegments of the organs of the human body].

OBJECTIVE: To emphasize the ubiquity of the anatomicosurgical segments and subsegments and to underscore their clinical and surgical importance, based upon recent advances in morphology, physiology, pathology, internal medicine and surgery. PURPOSE: To update basic knowledge of the structure and its application in modern medicine and surgery, for more conservative approach to treat diseases of organs in most systems of the body. METHOD: Comparative study of the anatomico-surgical segments and subsegments already described. RESULTS: The data show that the concept of anatomicrosurgical segmentation is applicable to practically all organs. CONCLUSION: The segmentation of the structures of the body from the anatomical and surgical standpoints is another general principle of construction of the human body and of other mammals as well as in vertebrates. Such a new approach to evaluate the vascular and ductal components of each organ opens broader horizons to the treatment of diseases.
