The correct answer is c) lacunae. Lacunae are small spaces within the bone matrix that house osteocytes, the mature bone cells. These cavities are crucial for the maintenance of bone tissue as they allow for the exchange of nutrients and waste between the osteocytes and the surrounding bone matrix.
In contrast, central canals, also known as Haversian canals, are channels that run through the center of osteons and contain blood vessels and nerves. Lamellae are the concentric rings of bone matrix that surround these canals. Trabecular refers to the spongy bone structure found in certain bones, and Volkmann’s canals are the transverse channels that connect the central canals. Therefore, lacunae specifically refer to the lacunae where osteocytes reside.
