|
Osteoblasts build what?
|
Bone
|
|
|
|
What do osteoblasts do?
|
Synthesize & secrete collagen fibers & organic components to build bone matrix, and initiate calcification
|
|
|
|
What happens when osteoblasts surround themselves w/matrix?
|
They beome trapped and become osteocytes
|
|
|
|
What are osteocytes
|
Mature bone cells
|
|
|
|
What do Osteocytes do?
|
Maintain the tissue (exchange of nutrients & wastes with the blood)
|
|
|
|
What are osteoclasts?
|
Large white blood cells that are concentrated in the endosteum
|
|
|
|
What do osteoclasts do?
|
Releases lysomal enzymes & acids that digest protein and mineral components of the bone matrix. (resorption)
|
|
|
|
What is resorption?
|
Breakdown oof bone matrix...the normal development, growth, maintenance and repair of bone
|
|
|
|
What is compact bone tissue?
|
Forms external layer of bones, is the bulk of diaphyses of long bones. Protects & supports, resists stresses of weight/movement
|
|
|
|
The diaphysis is what part of the bone?
|
Bone shaft or body - long, cylindrical main portion of the bone.
|
|
|
|
Epiphyses is what part of the bone?
|
Distal and proximal ends of the bone
|
|
|
|
The metaphyses are what part of the bone?
|
Regions in a mature bone where the diaphysis joins the epiphyses
|
|
|
|
What is the epiphyseal plate?
|
In a growing bone each metaphysis includes an epiphyseal plate, a layer of hyaline cartilage that allows the diaphysis of the bone to grow in length
|
|
|
|
What is the articular cartilage?
|
A thin layer of hyaline cartilage covering the epiphysis
|
