Lesson 6 Flashcards
on going replacement of old bone tissue by new bone tissue
bone remodeling
removal of minerals and collagen fibers from bone by osteoclasts
Bone resorption
attaches tightly to the bone surface at the endosteum or periosteum during the process of bone resorption
osteoclasts
enhances synthesis of the proteins needed to build new bone
Nutrition
from pancreas that promotes bone growth by increasing the synthesis of bone proteins
insulin
destruction of bone extracellular matrix
bone resorption
addition of minerals and clagen fibers to bone by osteoblasts
bone deposition
results in formation of bone extracellular matrix
bone deposition
about how many percent of the total bone mass in the body is being remodeled
5%
bone remodeling may be triggered by factors such as
exercise, sedentary lifestyle, changes in diet
Process of Bone Resorption
Quiescent
Activation
Resorption
Formation
Mineralisation
Factors affecting bone growth and bone remodeling
MVH
- intake of Minerals
- intake of Vitamins
- Hormones
necessary during bone remodeling
Minerals, like calcium and phosphorus as well as magnesium, flouride, maganese
stimulates activity of osteoblasts
Vitamin A
needes for synthesis of collagen
Vitamin C
