Comparative Analysis of Dominant and Non‐Dominant Hands: a Cadaveric Study

Abstract

Comparing the muscularity and vasculature of the right and left hands could be used to determine handedness. An inferential hypothesis was formed to determine the likely dominant and non-dominant hand of two female and two male cadavers. The girth of the thenar and hypothenar muscles were measured and compared in both hands of each cadaver. The thenar muscles include the abductor pollicis brevis, flexor pollicis brevis, and opponens pollicis. The hypothenar muscles include abductor digiti minimi, flexor digiti minimi brevis and opponens digiti minimi. In addition, a map of the vasculature of the hands was analyzed to compare the position and variability in the branching of arteries and veins. This study will be conducted through the use of cadavers supplied by the University of California San Francisco's Willed Body Program, and through the use of San Francisco State University's Human Anatomy Laboratory. This poster will aptly showcase the findings and results of this study.
