What is Osteology? | Study of bone structure and treatment of bone disorders |
What are the functions of the Skeletal System? | Support, Protection, Movement, Mineral Homeostasis, Hemopoiesis, Storage of Fat |
What are the 7 Bone Structures? | Epiphysis, Metaphysis (growth plate), Diaphysis, Articular Cartilage, Periosteum, Medullary Cavity, Endosteum |
What is the epiphysis? | Either end of a long bone |
What is the metaphysis? | The Diaphysis and Epiphysis meeting point (growth plate) |
What is the diaphysis? | The Shaft/body of a long bone |
What is the Articular Cartilage? | Hyaline cartilage covering epiphyses (reduces friction) |
What is the Periosteum? | Tough CT covering outside of bone (Sharpey's perforating fibers) |
What is the Medullary Cavity? | Cavity containing fat/yellow marrow and blood vessels. Makes bones lighter |
What is the Endosteum? | Membranous inner lining of medullary cavity |

What are lacunae? | "Little Lakes" for osteocytes |
What are canaliculi? | "Small Channels"; Osteocytes breathe/eat/connect |

What are trabeculae? | "Little Beams"; Contains red and yellow marrow |
What are Epiphyseal Lines? | Where the Long Bone stops growing (after puberty) |
What are the phases of Bone Repair during a fracture? | Reactive, Reparative, Remodeling (Fear, Fix, Finish) |
What are the types of Fractures? | Open, Comminuted, Greenstick, Impacted, Potts, and Colles |
What does calcium homeostasis do? | Calcium Regulation |
What does Calcitonin do? | Puts the bone in |
