Osteocytes
No, it is found in the hollow cavity inside the bone.
bone lacuna
No. Yellow bone marrow is found in the hollow cavity inside the bone.
spongy bone
The small spaces in compact bone tissue that are holes that osteocytes live in are called lacunae (singular: lacuna). The canal that runs through the core of each osteon is the site of blood vessels and nerve fibers; these canals are called canaliculi. The lacuna can sometimes be seen as an empty space with the cell nucleus inside and sometimes the cell nucleus takes up the entire lacuna.
Compact bone is the solid, hard, outside part of the bone. It looks like ivory and is extremely strong. Holes and channels run through it, carrying blood vessels and nerves from the periosteum, the bone's membrane covering, to its inner parts.Cancellous bone, which looks like a sponge, is inside the compact bone.
The part of bone you are asking about is called compact bone, or cortical bone.
Bone tissue can be either spongey or compact. Compact bone is found on the walls of the shaft of bones while Spongey bone is found at the ends of the bone where joints are made.
Yes compact is on the outside while spongy is on the inside.
As the names suggest, compact bone is solid-looking, and forms the outer layers of all bone (and the shafts in long bones). Spongy bone looks like sponge, with small holes, and is found on the inside of bones and the expanded heads of long bones. As the names suggest, spongy bone is softer than the solid, compact bone. With the naked eye, you can see that the compact bone is smooth and located around the outside of a cross-section of bone. Spongy bone, on the other hand, is located on the inside and is very porous, like a sponge.
The compact bone is the outer part of the bone, and on the inside is the spongy bone. The spongy bone has small spaces which are filled with red bone marrow and some fat.
