What are the depressions in the osteons in which the osteocytes are set?

The depressions in the osteons where osteocytes are located are called lacunae. These small cavities house the osteocytes, which are mature bone cells responsible for maintaining the bone matrix. The lacunae are interconnected by tiny channels known as canaliculi, allowing communication and nutrient exchange between osteocytes and the surrounding bone tissue.
