Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An osteocyte “lives” in ____
A
lacunae
B
lamellae
C
Haversian canals
D
Volkmann’s canals
Explanation: 

Detailed explanation-1: -Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae. Small channels (canaliculi) radiate from the lacunae to the osteonic (haversian) canal to provide passageways through the hard matrix.

Detailed explanation-2: -Osteocytes, the cells residing within the bone matrix, make up between 90% to 95% of the cellular component in skeletally mature adult bone tissue.

Detailed explanation-3: -Osteocytes are the most abundant cell type in mature bone and are contained within small holes (lacunae) in the bone tissue [2].

Detailed explanation-4: -Osteocytes Structure An osteocyte is a stellate shaped cell that has processes radiating from it as an extension from its cytoplasm. It is these processes that travel through the canaliculi connecting lacunae to lacunae and to the blood supply. Each osteocyte varies in cell body dimension, no two alike.

Detailed explanation-5: -Spongy (Cancellous) Bone. Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles.
