Answer
a. Osteogenic cells are stem cells that develop from embryonic mesenchyme and then give rise to most other bone cell types.
b. Osteoblasts are bone-forming cells. They are roughly cuboidal or angular; they line up in a single layer on the bone surface under the endosteum and periosteum and resemble a cuboidal epithelium.
c. Osteocytes are former osteoblasts that have become trapped in the matrix they deposited.
d. Osteoclasts are bone-dissolving cells on the bone surfaces. They develop from the same bone marrow stem cells that give rise to the blood cells.
