a layer of fibrocartilage in the bottom of a groove in a bone through which a tendon runs.
Etymology: L, stratum, layer, forma, form, fibra, fiber, cartilago, cartilage
a structure made of fibrocartilage that forms a thin coating of osseous grooves through which tendons of certain muscles glide. Small masses of stratified fibrocartilage also develop in the tendons of some muscles that glide over bones, as in the tendons of the peroneus longus and the tibialis posterior. Compare circumferential fibrocartilage, connecting fibrocartilage, interarticular fibrocartilage.
