The surface of dog articular cartilage attached to subchondral bone shows many humps on its surface when examined with the scanning electron microscope. The situation here contrasts with that in man and rabbit where large numbers of pits are seen of the surface. Such species variations cast doubts on the idea that pits and humps play a vital role in joint mechanics and lubrication. Ridges and undulations were not found in normal dog cartilage attached to bone, but complex systems of ridges did develop when the cartilage was cut or detached from bone.

用扫描电子显微镜检查时，附着于软骨下骨的犬关节软骨表面可见许多隆起。这一情况与人和兔的情况形成对比，在人和兔的关节软骨表面可见大量凹坑。这种物种差异使人怀疑凹坑和隆起在关节力学和润滑中起关键作用这一观点。在附着于骨的正常犬软骨中未发现嵴和起伏，但当软骨从骨上切割或分离时，确实会形成复杂的嵴系统。
