前額骨骨相與體表表現

人像藝術在美術中占有極重要的地位，對藝用解剖學的研究是培養正確觀察、理解與表現人體外形的重要途徑。本文針對前額骨骨相與體表表現及附著其上的眉部進行分析。這是由於額部占了臉很大的面積，所以，在人像表現上也很重要。由於它在體表沒有明確的輪廓，如果不從表面解剖研究，形體是很難掌握的。而藝用解剖學上幾乎不見此類專文，因此有深入研究的必要。藝用解剖學是以「藝術的眼光」及「科學的態度」研究人體結構。在人體的繁複性與多變性中，歸納出體表變的規律，以幫助人體藝術工作者有效率的表現人體。本人經由醫學、藝用解剖學典籍、骨骼標本、解剖大體的研究及觀察生活及影片中的男女老少、東西方人種、美術作品中的表化現，再安排「光」的照射以說明「額部外形」的共性，並綜合出理論根據、實際狀況與美術表現。

Portrait art plays an important role in the field of fine arts. For the study of artistic anatomy, it is an important gateway to train ones ability to accurately observe, understand, and present human body configurations. In this work, we conducted an analysis on the appearance of the outer body and the attached eyebrow area of the forehead bone. The forehead occupies a larger area on the face compared to other facial features, which is important in a portrait display. As the human body surface is not explicit in contour, if one does not study the anatomy of the outer body, the configuration would be very difficult to grasp. Previous publications have not focused extensively on this feature; thus, it is essential for further research and studies. Artistic anatomy is the study of human body structure through artistic vision and scientific method. It sums up the rules and variations in human bodies to provide artists with a frame work in order to display their work more efficiently. In this study, medical science, anatomical theories, bone sample examinations and autopsy have been used. In addition, hundreds of photos and movies were used to study the display of the art works of live human beings; old and young, male and female, western and oriental races. During the research, spot light was applied to the head section for interpretation of their contour commonality; thus, the theory foundation, realistic status and display of fine arts are concluded.
