   Linked via "protein fibers"

   Composition of the Extracellular Matrix (ECM)
   The ECM is the defining feature of connective tissues and is synthesized primarily by resident cells such as fibroblasts, chondrocytes, and osteocytes. It consists fundamentally of two components: ground substance and specialized protein fibers.

2. Connective Tissues

   Linked via "protein fibers"

   Fibrous Components
   The mechanical strength of connective tissues derives from three main classes of protein fibers embedded within the ground substance:
   Collagen Fibers: The most abundant proteins in the human body, collagens confer tensile strength. Type I collagen, prevalent in tendons and bone/, exhibits a [helical quaternary structure](/entries/helical-qu…
