Synovium

Membrana synovialis capsulae articularis.
Superficies membranae internae (rubre)
vocatur membrana synovialis.

Membrana synovialis sive stratum synoviale sive synovium sensu strictu est tela superficei membranae internae ("intima"), quae liquorem synovialem secernit. Illa ex cellulis macrophago (cellula typi A) similibus ac fibroblastis (cellulis typi B) constituta est[1]. Quadrans cellularum sunt macrophagorum, dodrans fibroblastorum, posterioribus enim cellularum functio secretionis acidi hyaluronici[2] ad articulationem lubricandam praestant. Macrophagi invicem leucocyti pars systematis immunitatis sunt. Nimirum morbis articuli causa vero relatio inter cellulas typi A et B graviter mutet cum incremento numeri macrophagorum. Praeterea fibroblasti transformationem patiantur, ut cellulis inflammatoriis cognoscantur, quo fiat, ut inflammatio chronica oriatur.

Subiacens tela subintima dicitur, cum vasis sanguineis tenuibus et lymphaceis.

Anatomia synovii

Stratum synoviale est pars interior bursae synovialis, breviter "intima" dicitur. Crassitudo eius est 20 µm - 40 µm[3]. In strato synoviali ("intima") duo genera celluarum inveniuntur: macrophagi cellulae typi A notae, atque fibroblast cellulae typi B. Sub intimam vasa sanguinea tenuia locata sunt, per quae prius macrophagi foetales intrati sunt, aliquanto post monocyti sic intrant et tunc in strato synoviali in macrophagos transformari videntur. Fibroblasti forma specialis, synoviocytus enim, exstant[4].

Cellulae strati synovialis

Adhuc imprimis duo typi cellularum synovii significationem se adoptaverunt, cellulae synoviales macrophagis similes enim (typi A) ac cellulae synoviales fibroblastis similes (typi B). Nuper telocyti, grex cellularum novus, quoque in membranis synovialibus descripti sunt[5].

Macrophagocyti

Conferatur pagina principalis macrophagocytus.

Macrophagocyti cellulae systematis immunitatis sunt leucocyti voraces.

Fibroblasti

Conferatur pagina principalis fibroblastus.

Fibroblasti generant et acido hyaluronico et collageno secernentibus matrices extracellulares, quarum syntheses superfluentes abundantiam reticulorum endoplasmaticorum intra fibroblastos explicant. Sicuti proteina, ut proteoglycan 4 (lubricinum) ad articulum lubricandum, secernuntur.

Membrana synovialis aegrota

Inflammatio

Inflammationes synovii integritatem eius adoriuntur et etiam perpetuo aequilibrium interrumpere queant, quo fit ut non solum macrophagi fibroblastique vero etiam monocyti assultati in membrana synoviali discerni possunt[6]. Nonnulli morbi rheumatologici cum functionibus membranae synovialis interagunt, utputa arthritis rheumatoidea. Macrophagi transformati enzymos cartilaginem ossaque destruentes superfabricant[7].
