The size and distribution of pacinian corpuscles were investigated in the palmar aspect of both hands of the monkey, Macaca fuscata. Most pacinian corpuscles were located in the dermis (dermal type) and subcutaneous tissue (subcutaneous type) throughout the hand. On light microscopy there were no differences in the structure of these 2 types, although almost all the subcutaneous type had a greater longitudinal dimension than the dermal type. Corpuscles were oval or elliptical and their longitudinal and transverse dimensions varied from 156 to 2025 microns and 88 to 1240 microns, respectively. Many pacinian corpuscles were in close relation to the small blood vessels, and their diameters were as large as those of capillaries. There were 458 corpuscles (dermal type: subcutaneous type = 140:318) in the right hand and 416 (186:230) in the left hand. About 40% of the corpuscles in each hand were found in the digital region; the remainder were located in the palm. The mean number of corpuscles in each finger was 33 and they were concentrated in the distal and middle phalanges. In the palmar region, most corpuscles were localised in the 2nd and 3rd interdigital eminences and the thenar and hypothenar eminences.
在猕猴（日本猕猴）双手的掌面研究了环层小体的大小和分布。在整个手部，大多数环层小体位于真皮（真皮型）和皮下组织（皮下型）。在光学显微镜下，这两种类型的结构没有差异，尽管几乎所有皮下型的纵向尺寸都比真皮型大。小体呈椭圆形或椭圆状，其纵向和横向尺寸分别从156至2025微米和88至1240微米不等。许多环层小体与小血管关系密切，其直径与毛细血管的直径一样大。右手有458个小体（真皮型：皮下型 = 140:318），左手有416个（186:230）。每只手约40%的小体位于手指区域；其余位于手掌。每个手指小体的平均数为33个，且集中在远节指骨和中节指骨。在手掌区域，大多数小体位于第2和第3指蹼隆起以及大鱼际和小鱼际隆起处。
