应用血管铸型方法,在扫描电镜下,观察了手掌与足底皮肤内的血管构筑形态,发观因部位不同两者间有显著的区别,即乳头层、乳头下层和真皮深层内该两部位的血管网均有不同的特点。本文目的在于提出并试图解释这些不同点。 Under the scanning electron microscopy, the vasculature structures in the skin of the palms and the plantar were observed by using the vascular casting method. There were significant differences between the two parts due to different parts of the skin, namely, the papillary layer, the inferior layer of the nipple and the deep layer of the dermis The vascular network has different characteristics. The purpose of this article is to propose and try to explain these differences.
