100
Originate from mesenchymal stem cells
What are osteoblasts and osteocytes?
100
Composition of osteoid
What are proteins and Type I collagen?
100
Concentric lamellae around a haversian canal
What is compact (or cortical bone)?
100
This type of joint allows for the most movement
What is a synovial joint (or diarthrosis)?
100
Bony fusion is successful, but is not in normal anatomic position
What is malunion?
200
Main responsibility is bone resorption
What are osteoclasts?
200
Precipitation of calcium and phospate
What is hyroxyapatite?
200
Prevention and fixing of micro damage, response to mechanical loading, and release of ions
What is bone remodeling?
200
Bones are connected with hyaline cartilage which allows some movement
What is a synchondrosis?
200
Abnormal, excessive bone remodeling with deposition of unorganized bone
What is Paget's disease?
300
Function as mechanoreceptors
What are osteocytes?
300
Fill gaps between collagen fibrils increasing strength
What are minerals?
300
Allow for nutrient and waste transportation into and out of cancellous bone
What are trabeculae?
300
Synovial joint component with rich blood, lymph, and nerve supply
What is the articular (joint) capsule?
300
Processes involved during step 2 in the physiology of a fracture
What are vasodilation, leukocytes, macrophages, and cytokines (or inflammatory response)?
400
First step in development of long bones
What is chondrocyte formation and hypertrophy?
400
Polysaccharide complexes responsible for regulating movement of ions and water
What are proteoglycans?
400
Cartilage and collagen are produced by fibroblasts and osteoblasts in response to gross injury
What is procallus (granulation tissue) formation (or what is step 2 of bone repair)?
400
Components of synovial joint that REQUIRES movement to function properly
What are proteoglycans?
400
Fracture with only partial contact between articulation surfaces
What is a complex subluxation?
500
Stimulates differentiation of MSCs into osteoblasts and increases osteoblastic activity
What is 1, 25 dihydroxy-vitamin D (or coupling factors)?
500
Stabilizes environment so ions bind together in a certain manner to maintain strength in bone
What is water?
500
Location of majority of trabecular bone in long bones
What is the epiphysis?
500
Cells responsible for secretion of hyaluronate and phagocytosis within diarthroses
What are Type A and B cells in the synovial membrane?
500
Difference between damage in osteoarthritis and rheumatoid arthritis
What is damage to articular cartilage vs. damage to cartilage, bone and synovium?
