Striking synovial structures were taken and their surface was investigated by scanning electron microscopy. Depending where the probes were taken from, the stratum synovial was arranged in a different way. The synovial intima seems to miss under the tendon of the long/commune extensor muscle, the collateral ligaments and the sesamoidean collateral ligaments. That is why the subsynovial tissue forms the superficial layer. The surface of the probes taken sidewards to the tendon of the extensor muscle and of the synovial fold, which is situated between the metacarpus/metatarsus and the proximal phalanx as well as from the palmar/plantar recess is dominated by synovial intima. Synovial cells are mainly arranged as monolayer. Synovial cells are variable in their appearance. Some resemble blackberrys, others show a quite undulating surface. The length of processes of synovial cells differs from 2-10 microns, the diameter of the synovial cells from 5-10 microns. The space between two cells amounts to 2-10 microns. The intercellular gap is put in relation to the length of the cells' processes. The synovial intima is supposed to form a barrier between the articular cavity and the surrounding structures.
取出显著的滑膜结构,并用扫描电子显微镜研究其表面。根据取材部位的不同,滑膜层的排列方式也有所不同。在长伸肌/总伸肌肌腱、侧副韧带和籽骨侧副韧带下方,滑膜内膜似乎缺失。因此,滑膜下组织形成了表层。取自伸肌肌腱侧向、位于掌骨/跖骨与近端指骨之间的滑膜襞以及掌侧/跖侧隐窝的样本表面,主要由滑膜内膜构成。滑膜细胞主要呈单层排列。滑膜细胞的外观各不相同。有些类似黑莓,另一些则呈现出相当起伏的表面。滑膜细胞的突起长度在2 - 10微米之间,滑膜细胞的直径在5 - 10微米之间。两个细胞之间的间隙为2 - 10微米。细胞间隙与细胞突起的长度相关。滑膜内膜被认为在关节腔与周围结构之间形成了一道屏障。
