bone and cartilage Flashcards
Tough, flexible form of connective tissue, characterized by an extracellular matrix (ECM) with high concentrations of GAGs and proteoglycans, which interact with collagen and elastic fibers.
a. tendon
b. cartilage
c. bone
c. connective tissue
cartilage
Cartilage consists of cells called ____ that are embedded in an extensive ECM. It synthesize and maintain ECM components and are located in matrix cavities called lacunae .
a. Chondrocytes
b. Osteocytes
c. Monocytes
chondrocytes
A sheath of dense connective tissue that surrounds cartilage in most places, forming an interface between the cartilage and the tissues supported by the cartilage.
a. Chondrocytes
