中指主要血管神经的断面观测

用２７例成人中指作组织切片后，取近侧，中间和锭侧指横纹及相邻指横纹中点处的横断面切片，对指掌侧固有动脉，神经及静脉的位置，管径进行了观测。指掌桡侧固有动脉，神经在－Ⅰ，Ⅱ，Ⅲ，Ⅴ断面中的４，５区和ＩＶ断中３，４区内的出现率都高于９０％，它们纵径的平均值分别大于０．８０ｍｍ和１．３０ｍｍ。

AN OBSERVATION ON RLOOD VESSELS AND NERVES IN SECTIONS OF MIDDLE FINGER

The sections were made on the middle fingers of 27 adults at the proximal, middle and distal transvcrs digital stria and at the middle of the adjacent transvers digital stria. The position and diameter of the proper palmar arteries, nerves and veins were observed and measured. The results were as follows: The radial proper palmar digital arteries and nerves appearing in Region 4, 5 of Section I, II, III, V and in Region 3, 4 of Section IV accounted for 90% and their average longitudinal diameters were above 0. 80 mm and 1. 30 mm respectively. The ulnar proper palmar digital arteries and nerves appearing in Region 8, 9 of Section I, II, III, V accounted for 100% and in Region 9, 10 of Section IV 90%, and their average logitudinal diameters were above 0. 80 mm and 1.20 mm respectively.
