Firstly lacuna is a place where something is missing in a piece of writing, idea, theory e.t.c. Hope u know this. Medically: Bone Lacuna is a small cavity within the bone matrix containing an osteocyte and from which slender canaliculi radiate and penetrate the adjacent lamellae to anastomose with the canaliculi of neighbouring lacunae, thus forming a system of cavities interconnected by minute canals
Lacuna is not bone. Lacuna is an empty space located in bones and other tissues.
Lacunae are little self perpetuating islands of connective tissue that separate a condrocyte from the immediate extra cellular matrix.

Yes, they divide, and as they divide, they create bone matrix and collagen fibers. As the osteoblasts become surrounded by the bone matrix, it hardens, enclosing the cells in a lacuna, transforming them into osteocytes. Osteocytes cannot divide.
Bone is a hard substance made of lots of composits, it has a spongy marrow centre where blood vessels are made and it has veins and stuff running through it. When you break your ankle, structures called Osteoblasts begin to repair it. It also contains more complex structures such as haversian system, canaliculi, lamellae, lacuna. blood cells are made in your bone by marrow but the blood vessels are not made in the bone, they have them but dont make them.
Osteoblasts are one type of bone cell (out of three) that is found in bone tissue. They are bone forming cells (make bone) (bone builders). It deposits bone even as another bone cell, osteoclasts, breaks it down. When there is a break, or lacuna, in the bone the osteoblasts form a sheet over the gap. Then osteoids cover the osteoblats trapping them in the lacuna. Inside the lacuna they then turn into osteocytes, a type of bone cell.osteoblasts are bone forming cells, and osteoclasts are bone destroying cells.Osteoblasts (from the Greek words for "bone" and "germ" or embryonic) are mononucleate cells that are responsible for bone formation; in essence, osteoblasts are sophisticated fibroblasts that express all genes that fibroblasts express, with the addition of the genes for bone sialoprotein and osteocalcin.[1]Osteoblasts produce osteoid, which is composed mainly of Type I collagen. Osteoblasts are also responsible for mineralization of the osteoid matrix. Zinc, copper and sodium are some of the many minerals produced. Bone is a dynamic tissue that is constantly being reshaped by osteoblasts, which build bone, and osteoclasts, which resorb bone. Osteoblast cells tend to decrease as individuals become elderly, thus decreasing the natural renovation of the bone tissue.[2]osteoblasts produce bones in the body. they are bone producing cellsAn osteoblast is an immature bone cell. Eventually, the osteoblast will mature into an osteocyte and ossify, or harden, into bone.Living cells within the bone are engaged in an unceasing process of remodeling. Osteoblasts lining the surface of bone are much like fibroblasts and deposit and organize new bone matrix while osteoclasts demolish old bone matrix. Osteoblasts are converted into osteocytes as they become embedded in this matrix and the matrix calcifies.
Steps: 1. Mesenchyme cells differentiate into osteoblasts and start to secrete matrix 2. Osteoblasts form spicules of matrix 3. Spicules trap osteoblasts in lacuna 4. Activity slows 5. Trapped osteoblasts called osteocytes 6. Bone growth proceeds outward from center (ossification center) 7. Spicules thicken into trabeculae (spongy bone) 8. Trabeculae connect (compact bone)

Osteocytes
Osteocyte: a cell that is characteristic of adult bone and is isolated in a lacuna of the bone substance
A lacuna is a small cavity or gap within a structure, such as in bone tissue where osteocytes reside. A lamella is a thin plate-like structure, such as the layers of bone tissue that form concentric circles around the Haversian canals. In bone tissue, lacunae house osteocytes, while lamellae provide structural support.
Osseous tissue has calcium, salts, and blood vessels.
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.
Lacunae is the plural version of the word, lacuna. A lacuna is a small gap in bone or cartilage similar to a dent or depression. A lacuna can also be a gap in a story line where the reader is left up to their imagination when the plot shifts radically.
The Lacuna was created in 2009.
Lacuna Coil is from Milan,Italy.
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.
Mahatha lacuna was created in 2005.
Jessie Lacuna was born in 1993.
