Bone formation & growth
100
The 5 functions of the skeletal system.
What are support, protection, movement, storage of nutrients and blood cell formation?
100
The two ways bones are classified
What are composition and shape?
100
The shaft of a long bone.
What is the diaphysis?
100
Mature bone cells.
What are osteocytes?
100
The process of bone formation.
What is ossification?
200
The location of blood cell formation.
What is red bone marrow?
200
The two types of bone classification based on composition
What are spongy and compact?
200
The ends of the long bone.
What are the epiphyses?
200
The type of bone matrix found in the diaphysis.
What is compact bone?
200
Bone forming cells.
What are osteoblasts?
300
Portion of the skeleton that protects the vital organs.
What is the axial skeleton?
300
The femur, tibia and fibula are examples of this type of bone shape.
What is long bone?
300
In adults this is filled with yellow marrow. In fetuses, it is filled with red marrow.
What is the medullary cavity?
300
Canals that run into the bone at 90 deg. angles.
What are perforating (Volkmann's) canals?
300
As the embryo develops to a fetus, this is replaced with bone.
What is the hyaline cartilage model?
400
The body system that uses the skeletal system as levers to allow the body to move.
What is the muscular system?
400
These cubed-shaped bones are made of mostly spongy bone and can be found in your wrist and ankle.
What are short bones?
400
The covers the epiphyses of the long bone, allowing for smooth joint movement.
What is articular (hyaline) cartilage?
400
The concentric circles of lacunae (the cavities on which osteocytes are found).
What are lamellae?
400
Growth in length occurs here.
What is the epiphyseal plate?
500
The bones are an important storage facility for this mineral.
What is calcium?
500
These have a layer of spongy bone sandwiched between tow layers of compact bone and can be found in your skull, ribs and sternum.
What are flat bones?
500
This covers and protects the diaphysis.
What is the periosteum?
500
The canal at the middle of an osteon.
What are central (Haversian) canals?
500
Bone destroying cells.
What are osteoclasts?
