Structures
What is diaphysis?
What is Open or Compound fracture?
Cylindrical bone; example: femur
What are long bones?
Cells that decrease blood calcium by secreting bone matrix
What are osteoblasts?
Support, protect, levers for movement, mineral storage, blood cell formation
What are functions of skeletal system?
A hole in bone
What is Foramen?
Type of bone growth/development where bone is formed directly from mesenchymal cells, not cartilage template
What is intramembranous ossification?
broad, sheetlike bones, example sternum
What are flat bones?
Cells of bone that are trapped in lacunae and now maintain the bone around them
What are osteocytes?
Hyaline cartilage found at the ends of bone
What is articulating cartilage?
Membrane that lines the medullary cavity
What is endosteum?
Trabeculae is the main unit of this type of bone

The functional unit of compact bone
What is osteon? or Haversian System?
Various shapes and sizes, example vertebrae
What are irregular bones?
Cells of the skeletal system that increase blood calcium by eroding bone matrix
What are osteoclasts?
Type of bone development where bone grows appositionally replacing the cartilage template
What is endochondral ossification?
Articulations in the skull are called
What are sutures?
Blood calcium is primarily regulated by this gland which secretes a hormone that increases blood calcium levels
What is the Parathyroid?
seedlike bones, example the patella
What are sesamoid bones?
Modified cells that are stem cell like of the skeletal system that can differentiate into many different cells
What are osteogenic cells? Progenitor cells? Mesenchymal cells?
Hormone produced and secreted by the thyroid in response to high blood calcium levels
