Detailed explanation-1: -Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
Detailed explanation-2: -Each osteocyte is located in a small cavity in the bone tissue called a lacuna (lacunae for plural).
Detailed explanation-3: -Bone lacunae are small, spindle-shaped spaces (appearing dark in this image), each containing an osteocyte that is left behind by osteoblasts during the process of remodelling.
Detailed explanation-4: -Each lacuna is occupied during life by a branched cell, termed an osteocyte, bone-cell or bone-corpuscle. Lacunae are connected to one another by small canals called canaliculi. A lacuna never contains more than one osteocyte. Sinuses are an example of lacuna.
