The cells' presence and activity is easily recognised based on three distinct morphological features: (i) multinuclearity, (ii) a multiply folded apical cell membrane (ruffled border), and (iii) deep lacunae (Howship's lacunae) that the cells eroded into the bone surface. Mononucleated osteoclasts without these features are considered to be inactive precursors.
