WebDec 18, 2024 · Histologically tendons consist of closely packed collagen fibers embedded in an extracellular matrix with tendon cells as well as non-fibrillar proteins as proteoglycan and elastin. The fibers are organized in fascicles that are surrounded by connective tissue the endotenon which is continuous with the epitenon covering the tendon surface 1-4 . Histologically, tendons consist of dense regular connective tissue. The main cellular component of tendons are specialized fibroblasts called tendon cells (tenocytes). Tenocytes synthesize the extracellular matrix of tendons, abundant in densely packed collagen fibers. The collagen fibers are parallel to each other and organized into tendon fascicles. Individual fascicles are bound by the endotendineum, which is a delicate loose connective tissue containing thin collagen fibrils and e…
