Chapter 6 Bone Cells Flashcards
1
Q
Osteoprogenitors (Osteogenic cells)
A
Flat looking Make Progeny/ stem cells of the periosteum and endosteum
2
Q
Osteoblast cells
A
Blast Build. Secrete bone matrix (collagen and enzymes that make hydroxyapatite crystals)
3
Q
Osteocytes
A
Cytes: mature cells. They maintain the matrix.
4
Q
Osteoclasts
A
Coast cut. Break down the matrix for remodeling. Arises from white blood cells.
5
Q
A
6
Q
Lacunae
A
“Rooms” that osteocytes are housed in
7
Q
Osteocytes are responsible for:
A
Attaching their projections/ spider arms to the matrix that allow communication & diffusion gap junctions. They also monitor bone stress and contribute to Ca+ homeostasis.
8
Q
Osteoclast are responsible for
A
Clast cut. Break down bone and reabsorb.
