Explain the support function of the bone
Provides a framework for the rest of our body
Name four Appendicular Bones

At what age does endochondral ossification begin?
6 to 8 weeks
What type of break occurs only in children?
Greenstick
What are the 4 types of bone cells
Osteogenic cells, Osteoblast, Osteocyte, Osteoclast
What hormone does the bone produce as part of its function?

Name the 5 different bone types
Short, Long, Sesamoid, Flat, Irregular
What is the perichondrium?
A layer of cartilage around the original cartilage model.
A fracture occurred that broke the skin. it was a clean break. Name 4 types of breaks that can best describe this fracture.
Complete, transfer/oblique, open, displace
Osteogenic cells
What two minerals are stored in the bone?
Calcium and Phosphate
What organ is best protected by a flat bone?
Brain, Lungs, or heart
List the 6 steps of Ossification in order
1) Cartilage model forms, 2) Perichondrium and periosteum form, 3) primary ossification center, 4) medullary cavity, 5) secondary ossification centers, and 6) ossification is complete.
What is the process of bone remodeling?
Hematoma Forms, Soft Callus, Soft callus ossifies into a bone callus, bone remodeling
What location of a long bone will you find Osteoblasts?
Periosteum and Epiphyseal Plate
What is Hematopoiesis, and under what function does it fall?
To make blood; Blood Cell Formation
provide an example of all 5 bone types
Carpals/tarsals: short. Femur, phalanges, meta-tarsals/carpals, humerus, radius/ulna, tibia/fibula: Long. Vertebrae: irregular. Patella: sesamoid. Ribs, sternum, cranium: Flat.
explain how an ossification center is formed
The surrounding Perichondrium ossifies into bone, the new periosteum cuts off nutrients to the cartilage inside, turning it into bone. Blood vessels enter into the ossification center so that the building of the bone may continue growing from the inside-out.
What is the difference between a closed and open reduction?
A closed reduction is when a doctor uses their hands to set the ends of the bones back into alignment. An open reduction is when surgery is necessary to secure the ends of the bone together with screws or plates.
Name 3 structures of the bone located in the proximal epiphysis of the femur
Articular Cartilage, Spongy bone, Epiphyseal plate, and Red Marrow
