epineurium noun[ C or U ] anatomy specializeduk /ˌep.ɪˈnjʊə.ri.əm/ us /ˌep.əˈnʊr.i.əm/pluralepineuriauk /ˌep.ɪˈnjʊə.ri.ə/ us /ˌep.əˈnʊr.i.ə/ a layer of tissue around a set of nerves that protects them : A well-developed epineurium protects nerves against compressive and tensile stresses. Injured nerves at two weeks had thinner epineuria compared to normal nerves. These nerve roots are particularly susceptible to injury, since they have a poorly developed epineurium. The internal epineurium is a loose collection of collagen and elastin fibres that support the fascicles of a peripheral nerve. Stretched beyond the elastic limit, the axons tear, but the surrounding epineurium remains intact.
