Bone Cells
These bone stem cells turn into osteoblasts.
What are osteoprogenitor cells?
This type of bone is more dense and organized into rings.
What is compact bone?
The technical name for the growth plate.
What is the epiphyseal plate?
The first step in bone fracture healing.
What is hematoma formation?
This marrow stores fat for energy.
What is yellow bone marrow?
These cells make the extracellular matrix of bone.
What are osteoblasts?
The rings of calcified matrix in compact bone are called these.
What are lamellae?
This shows that the bones are still growing.
What is the presence of the epiphyseal plate?
The soft cartilage stage of fracture repair.
What is fibrocartilaginous callus formation?
This marrow produces blood cells and platelets.
What is red bone marrow?
Osteoblasts differentiate into these cells that maintain bone.
What are osteocytes?
This cavity in long bones stores yellow bone marrow.
What is the medullary cavity?
This tissue forms long bones in the embryo.
What is cartilage?
The stage where bone replaces cartilage.
What is bony callus formation?
Blood cell formation occurs here.
What is hematopoiesis in red bone marrow?
These large cells use acid to break down bone matrix.
What are osteoclasts?
This protective layer is not found at joint surfaces.
What is the periosteum?
Bone length increases at this location in long bones.
What is the epiphyseal plate between the epiphysis and diaphysis?
The final stage where bone reshapes itself.
What is bone remodeling?
Red bone marrow is found mainly in this type of bone.
What is spongy bone?
Osteocytes are found inside these small cavities.
What are lacunae?
This bone tissue contains red bone marrow.
What is spongy (cancellous) bone?
Osteoblasts and osteoclasts work here to increase bone diameter.
What is the periosteum and endosteum?
A fracture where the bone breaks through the skin.
What is an open/compound fracture?
The function and location of yellow bone marrow.
What is fat storage in the medullary cavity?
