The microvascular architecture of filiform papillae was investigated under a scanning electron microscope in man, Japanese monkeys, common squirrel monkeys, common marmosets, common tree shrews, large Japanese moles and dwarf shrews utilizing microvascular corrosion casts. Filiform papillae were circularly arranged in primates, and each of them was supplied by a hairpin capillary loop. These papillae sometimes were aggregated. The filiform papillae of Japanese monkeys exhibited markedly locational differences on the lingual dorsum and were supplied by circularly arranged capillary loops or by an intrapapillary capillary network. Small filiform papillae were located on an epithelial eminence in the lingual radix, each of them supplied by a low and simple hairpin capillary loop. The aggregated filiform papillae of common squirrel monkeys were less frequent without any locational differences. Low filiform papillae of common marmosets and tree shrews were simpler in form, being arranged in a circle and supplied by a simple hairpin capillary loop. The filiform papillae of insectivores were not arranged in a circle. The filiform papillae of dwarf shrews were supplied by an incomplete capillary ring without a loop. With respect to species differences, the circularly arranged capillary loops in man were most complicated and highly developed. Microvascular architecture of the filiform papillae of insectivores was much simpler, different from those observed in primates.
利用微血管铸型技术，在扫描电子显微镜下对人、日本猕猴、普通松鼠猴、普通狨猴、普通树鼩、大日本鼹鼠和倭鼩的丝状乳头微血管构筑进行了研究。丝状乳头在灵长类动物中呈环状排列，每个乳头由一个发夹状毛细血管袢供血。这些乳头有时会聚集在一起。日本猕猴的丝状乳头在舌背表现出明显的位置差异，由环状排列的毛细血管袢或乳头内毛细血管网供血。小的丝状乳头位于舌根的上皮隆起处，每个乳头由一个低而简单的发夹状毛细血管袢供血。普通松鼠猴聚集的丝状乳头较少见，且无位置差异。普通狨猴和树鼩的低丝状乳头形态较简单，呈环状排列，由一个简单的发夹状毛细血管袢供血。食虫动物的丝状乳头不呈环状排列。倭鼩的丝状乳头由一个不完整的无袢毛细血管环供血。就物种差异而言，人类中环状排列的毛细血管袢最为复杂且高度发达。食虫动物丝状乳头的微血管构筑要简单得多，与灵长类动物中观察到的不同。
