Measurements of capillary numbers, depths and dimensions were therefore carried out by light microscopy on synovial tissue sections from five rabbit knees. In addition the surface area of synovial tissue lining the joint was estimated, and the thickness of the synovium measured. Synovial capillary density was found to be uneven, with respect to both anatomical location in the joint cavity and depth below the synovial surface. The large area of synovium over areolar or adipose tissue was highly vascular (67000\u201383000 capillaries.cm<jats:sup>\u22122<\/jats:sup> section; mean intercapillary distance 35\u201355, \u00b5m; 228\u2013329 cm<jats:sup>2<\/jats:sup> endothelium.cm<jats:sup>\u22123<\/jats:sup> synovium). The small area of synovium over tendons was of very low vascularity (2000 capillaries.cm<jats:sup>\u22122<\/jats:sup> section). From these data and a previous estimate of net filtration capacity, mean synovial endothelial conductivity was estimated as \u223c 16 x 10<jats:sup>\u22127<\/jats:sup> cm.s<jats:sup>\u22121<\/jats:sup>.mmHg\u2212<jats:sup>1<\/jats:sup>. The depth distribution of the capillaries was extremely skewed, with a sharp peak at 6\u201311 \u00b5m depth. The rapid decay in capillary density at depths \u3009 6\u201311 \u00b5m was partly due to an uneven density of capillaries within the synovium itself; and partly due to a lower density in subsynovial tissues.<\/jats:p><jats:p>It was concluded that most synovium has a rich capillary bed which is very superficially located and that the depth of periarticular tissue which is effective in exchange processes with the joint cavity is less than 25 \u00b5m.<\/jats:p>","DOI":"10.1113\/expphysiol.1983.sp002753","type":"journal-article","created":{"date-parts":[[2014,12,16]],"date-time":"2014-12-16T17:22:59Z","timestamp":1418750579000},"page":"629-644","source":"Crossref","is-referenced-by-count":42,"title":["THE DENSITY AND DISTRIBUTION OF CAPILLARIES AROUND A SYNOVIAL CAVITY"],"prefix":"10.1113","volume":"68","author":[{"given":"A.
