Última Sexual Differences in the Diameter of Coronary Arteries in an Adult Sri Lankan Population International Journal of Morphology Ilayperuma,I; Nanayakkara,B. G; Palahepitiya,K. N. Coronary artery disease is a major cause of human mortality. It is stated that females have worse outcomes than men following myocardial infarction and coronary revascularization. Sexual differences in the coronary artery diameters have also been speculated as one of the reasons for the above outcome. However, because of possible confounding effects, such as the body size and heart weight, it is unclear if there is a true sex-specific effect on coronary arterial size. The present study was undertaken to investigate the sexual differences in the diameter of coronary arteries in a group of adult Sri Lankan population. The diameters of the coronary arteries and their branches were measured at predetermined sites in a total of one hundred and two apparently...

ABSTRACT Sexual dimorfism refers to morphological differences between males and females of a species. It may be a result of different selection pressures acting on either or both sexes and may occur in any sexually-reproducing dioecious species, including fishes. We analyzed 63 females and 63 adult males of Gymnorhamphichthys rondoni (Gymnotiformes) collected by us or deposited in museum collections. Sex was identified through abdominal dissection. We measured length from snout to posterior end of anal-fin, anal-fin length, distance from anus to anal-fin origin, distance from genital papilla to anal-fin origin, body width at beginning of anal-fin, and head length. Morphometric data submitted to a Principal Component Analysis (PCA) grouped males and females...
