compact and spongy
lacunae
Osteocytes become surrounded by bone matrix and are relatively inactive, but do have the capability to produce components needed to maintain the bone matrix if needed. Lacunae osteoblasts change into osteocytes.
Osteocytes are responsible for the maintenance and turnover of mineral content of surrounding bone. They are found in the flattened lacunae of bone tissue.
The Haversian Canal is connected to the lacunae by a system of interconnecting canals called the canaliculi.
Bone cells surround Haversian canals. Osteon (Haversian system) is the structural unity of bone. Spaces for osteocytes are called lacunae. The matrix is present in concentric rings called lamellae. Canaliculi are canals that join lacunae with the central Haversian canal (central canal)
lacunae
In bone the cells that occupy the lacunae are osteocytes.
Bone cells, osteocytes, reside in cavities within compact bone called lacunae.
Mature bone cells within the matrix are called osteocytes.
add me on facebook and i will tell you
canaliculus is a small channel or canal, as in bones, where they connect to lacunae. Lacuna is a small shallow space in the bones in which the osteocytes lie.
Bone canaliculi are narrow canals containing cytoplasmic processes of osteocytes. They are located in the space between the lacunae of ossified bone.
osteocytes
Osteocytes become surrounded by bone matrix and are relatively inactive, but do have the capability to produce components needed to maintain the bone matrix if needed. Lacunae osteoblasts change into osteocytes.
Osteocytes are arranged in rings in an osteon, the functional unit of a bone. They reside within the lacunae, which are gaps between the osteon's circumferential lamellae.
Osteocytes
Canaliculi are small, microscopic canals between the various lacunae of ossified bone. The radiating processes of the osteocytes project into these canals
