TitleUnpublished paper, 'On the anatomy and physiology of the vascular fringes in joints, and the sheaths of tendons' by G [George] Rainey
CreatorRainey; George (fl 1843-1857)
DateFebruary 1846
DescriptionRainey traces the presence of the synovial fringes in all cavities which contain synovia; that is to say, not only in the joints, but also in the sheaths of tendons, and in the bursæ mucosae. When well-injected, they are seen, under the microscope, to consist of two parts: a convolution of blood-vessels, and an investing epithelium. These convoluted vessels do not enclose, by their anastomoses, spaces like those capillaries which secrete fat, and which are of a much smaller size than the former; and the epithelial investments, besides enclosing separately each packet of convoluted vessels, sends off from each tubular sheath secondary processes of various shapes, into which no blood-vessels enter. The lamina itself, forming these folds and processes, consists of a very thin membrane studded with flattish oval cells, a little larger than blood-corpuscles, but destitute of nucleus or nucleoli; presenting none of the characters of tessellated epithelium, but corresponding more to what Mr. Goodsir has termed germinal membrane. Rainey concludes that the proper office of this structure is to secrete synovia; an office which Clopton Havers had assigned to them as long ago as the year 1691, although his opinion has not been generally adopted by later physiologists.
