Question

Quizplus · Accepted Answer

Osteoclasts have a unique structure in their cell membrane called ruffled borders, which are responsible for bone reabsorption. These borders are formed by numerous finger-like projections that extend into the bone tissue and secrete enzymes to dissolve the bone matrix. Canaliculi are tiny channels that connect the lacunae (small cavities) in bone tissue to allow nutrient exchange between osteocytes (mature bone cells). Lacunae are the small spaces in the bone matrix that house osteocytes. Crossroads and lamellae are unrelated to osteoclast function.
