skeletal system-- formation of bone Flashcards
what cells produce the extracellular matrix of bone tissues
chondrocytes, fibroblasts, and osteoblasts
what cell secretes substances that form the first stage in the production of extracellular matric of mature bone
osteoblasts
endochondral ossification begins with various physiological processes that progressively _______ and ______ cartilage version of bone
breakdown and reabsorb
endochondral ossification begins with various physiological processes that progressively breakdown and reabsorb cartilage version of bone while _______ continuously invades the collagen matrix
osteoblasts
what are the structural subunits that form born
osteons
what are the cylindrical columns that are tightly packed together in parallel arrangement in bone and often extend for the entire length of individual bones
osteons
what does the interconnected network provide
pathways for the flow of oxygen and nutrients to all regions of the bone
a small percentage of what becomes trapped within the extracellular matrix and the differentiate into osteocytes
osteoclasts —- which differentiates into osteocytes
what are the cavities within bone that contain loose connective matrix and hematopoietic activity and a high content of adipocytes
bone marrow
what is the outer membrane of bones
periosteum
what contains numerous nerve fibers and pain fibers
periosteum
what decomposes bone activities
osteoclasts
what cell performs bone formation activities
osteoblasts
what happens to the bones that are at regions where osteoblasts activity exceeds osteoclasts activity
bone thickens
what happens to bone that exceed osteoblast activity
bone reabsorbs and thins
