Tissue and injury repair quiz 3
Terms in this set (10)
True or False: Like skin wound healing, bone injury and repair involves the formation of a fibrous scar or callus.
What is the most common form of fracture healing that typically occurs in non-operative fracture treatment?
indirect fracture healing
For the regeneration of bone, which cells have to be recruited, proliferate, and differentiate into osteogenic cells?
mesenchymal stem cells (MSCs)
Which process peaks around day 7-9 after a bone injury in animal models and is evident by a peak in type II procollagen and proteoglycan, core protein extracellular markers?
soft callus formation
True or False: The angiopoietin-dependent pathway of the vascularization process is considered to be the key regulator of vascular regeneration and promotes revascularization of the cartilaginous matrix.
At what day post-injury does hard callus formation usually peak in animal models?
Fill in the blanks: During bone remodeling, ___________ resorb the hard callus while ___________ deposit lamellar bone to more fully restore the biomechanical properties of normal bone.
Which of the following is NOT true regarding direct fracture healing?
direct fracture healing involves the formation of periosteal callus
Which type of fracture healing process involves filling of the fracture site with lamellar bone that is oriented perpendicular to the long axis, which requires secondary remodeling?
We know Wolff's Law to be true in bone due to the following examples: long bone is thickest at the middle of the bone where the bending forces are the greatest and tubercles/tuberosities form where tendons insert due to tensile forces of muscle transmitted to bone.
