Cards in this deck (27)
- 1PeriostiumBones Outer Lining
- 2EndostiumInner Lining of the Bone
- 3Periostial ArteryProvides periostium and compact bone
- 4Nutrient ArteryPierces compact bone & supplies medullary cavity, spongy bone & deeper compact bone
- 5EpipysisTop and bottom of long bone (spongy bone)
- 6MetaphysisActively dividing area that increases bone length
- 7DiaphysisLong thin part of long bone (contains mostly compact bone)
- 8Epiphyseal arterySupplies epiphysis with blood
- 9Metaphyseal arterySupplies metaphysis with blood
- 10Bone is made of...A calcified extracellular matrix and bone cells
- 11What determines flexibility in bone?Collagen
- 12Skeletal system is divided into two parts- what are theyAxial & Appendicular Skeleton
- 13Osteoblasts in the epiphyseal plate...Increase bone length
- 14Osteoblasts in the inner/outer periostium...Increase bone width
- 15Spongy bone histologyNo specific structure
- 16Why are there spaces between trebaculae?To allow for bone marrow
- 17Spongy bone with a thin layer of compact bone is usually found in...Short/flat/irregular bones
- 18Bone formation begins at...6 weeks (in a fetus)
- 19Mesanchyme CellsPotentially differentiate into bone cells
- 202 Methods of fetal bone formation....Endochondral and Intramembranous
- 21Endochondral Bone FormationDevelops on a cartilaginous model
