Cartilage primarily receives its nutrition from ____________________

a. its high level of permeability
b. diffusion
c. a process of joint loading and unloading

ANS: C
Although the synovial fluid providing nutrition to cartilage has a low degree of permeability
allowing for some diffusion, the process of joint loading and unloading provides a larger-scale
exchange of synovial fluid, allowing the more nutrition-rich fluid into the cartilage.
