Some people develop such breakdown and wear to joints that they no longer function properly.Physicians can surgically replace these joints with artificial joints.However, after surgery the artificial joints tend to come loose from their attachment points over time unless they are covered with biological coatings that contain proteins present in the human extracellular matrix.Which function of the extracellular matrix is highlighted in this instance?
A) Filtration of materials passing between different tissues
B) Orientation of cell movements during development
C) Strengthening of bone, cartilage, and skin
D) Recognition of cells and cell-to-cell adhesion
E) Providing a medium for chemical signals to move between cells

Question

Quizplus · Accepted Answer

The extracellular matrix functions in cell recognition and cell-to-cell adhesion, which is critical for proper attachment and integration of the artificial joint in this case. Without the appropriate proteins in the biological coatings, the body may reject the artificial joint or the joint may become loose over time.
