関東地方の縄文時代より近代初期まで,各時代人の平均身長を推定し,これに既発表の現代人の生体計測による資料を加えて縄文時代より現代までの身長の時代変化を検討した.繩文時代より近代初期(明治維新より1900年まで)までの各時代人の推定身長は大腿骨をもちいた身長推定式によって算出した.推定式は藤井(1960)の報告による大腿骨最大長の身長推定式をもちいた.結果は男女ともに繩文時代人より古墳時代人が大きく,以降,鎌倉時代,室町時代,江戸時代,そして近代初期へと順次身長が低下してきたことが推測される。そして現代においては急激な身長の増加が生じている.また現代人の身長は古墳時代人よりも大きくなっている.

The author made a topographic anatomical study of the sphenoid bone of the male Middle Kyushuites and compared their topographical features with those of some other authors. Although there have been many roentgenologic studies of the turkish saddle, a few topographic anatomical studies of the dried sphenoid bone have been referred to. The authors of these studies are as follows : Nakahara (1953), Nishimura (1957), Mashimo et al. (1964), Saigusa (1933), Hoshi (1958), Dodo (1974). The sphenoid bone not only has the round, oval and spinous foramen, but also makes the internal orifice of carotid canal and the turkish saddle. Furthermore, it has the pterygoidal process. Their morphological features were observed according to certain classifications and measured. The results were briefly summed up as follows. 1. The following types of the observational features showed the highest percentage in the Middle Kyushuites as well as in the Kantoites : the transverse ellipse type of the hypophyseal fossa, the concave type of the floor of the turkish saddle, the round type of the round foramen, the ellipse type of the oval foramen, the round type of the spinous foramen. 2. The internal orifice of carotid canal showed the highest percentage of the C-type in the Middle Kyushuites and in the Kantoites. 3. The following observational items showed no statistically significant differences among the Middle Kyushuites, the Tohokuites and the Kantoites : Pterygo-spinous foramen, Foramen ovale incomplete, Clinoid bridging. 4. The Middle Kyushuites showed the highest percentage of 75.0% in the foramen of Vesalius. It was significantly higher than the frequencies of the Tohokuites and the Kantoites. 5. The pterygo-basal bridging occurred in 5.8% of the Middle Kyushuites. 6. The pterygoidal process showed the highest percentage of the E-type in the Middle Kyushuites, but of the B-type in the Kantoites. 7. The turkish saddle of the Middle Kyushuites tended to be shallower than that of the Kyotoites, and was shallower than that of the Hokurikuites. 8. As for the maximum and transverse diameters of the oval foramen, there were no statistically significant differences among the Middle Kyushuites, the Kantoites and the Germans. 9. Distances between centers of foramens on both sides in the Middle Kyushuites were nearly equal to those in the Kantoites. 10. The shortest distance in the external cranial fossa between the oval and the spinous foramens was significantly shorter in the Middle Kyushuites than in the Kantoites. 11. Ratio of totaled projected area of the greater wings to that of the lesser wing was 1.72. Ratio of totaled projected area of the lesser wing to that of the body was 1.10. Ratio of totaled projected area of the greater wings to that of the body was 1.86. 12. Between the Middle Kyushuites and the Kantoites, the measurements and indices of the pterygoidal process showed significant differences as follows ; the length of the pterygoidal process in both sides, the middle breadth of the pterygoidal fossa in the right side, and the length-breadth index of the pterygoidal fossa in both sides of the Middle Kyushuites were larger than those of the Kantoites. In the contrary, the following items in the Middle Kyushuites were smaller than those in the Kantoites ; the greatest length of the pterygoidal fossa in the right side, the greatest depth of the pterygoidal fossa in the left side, the breadth-depth index of the pterygoidal fossa in both sides, and the angle of lower edge of the lateral plate in both side, respectively. The differences in the other measurements and indicies were insignificant between the two groups.

運動器において骨の計量化はMartin(1928)によって体系化され, その手法による骨の形態に関しての解析が進展している. 同じ運動器に属する軟部組織のなかでは, 筋に関する計量化のみが広く研究されているが, その他では殆ど行われていない. 運動機能上重要な役割をもつヒトの足底鍵膜に着目し, その経側腓膜の計量化を試みた. 8項目からなる計測を行い, 左右差をt検定法によって行ったが, 有意差を示したものは前腱側鍵膜厚で, 右側が左側より有意に厚かった. 8項目中6項目は有意差を検出できなかったが, 右側は左側より大きな値をとる傾向が見られた.(1982年11月15日 受付)
