angiogenesis
Formation of new blood vessels. the process by which a wound is vascularized in order to bring nutrients to the healing area & remove debris. These new vessels are considered "leaky" & are usually temporary.
cicatrix
A scar left by the formation of new connective tissue over a healing sore or wound
collagen
Produced by fibroblasts,
The fibrous protein constituent of bone, cartilage, tendon, & other connective tissue. It is converted into gelatin by boiling
debridement
Surgical excision of dead, devitalized, or contaminated tissue & removal of foreign matter from a wound
fibronectin
A type of large glycoprotein that is found on the surface of cells & mediates cellular adhesion, control of cell shape, & cell migration
granulation tissue
Small, fleshy, beadlike protuberances, consisting of outgrowths of new capillaries, on the surface of a wound that is healing
keloid
A red, raised formation of fibrous scar tissue caused by excessive tissue repair in response to trauma or surgical incision
organization
Functional impairment of tissue involved in wound healing
proud flesh
The swollen flesh that surrounds a healing wound, caused by excessive granulation
resolution
The subsiding or termination of an abnormal condition, such as a fever or an inflammation
wound contraction
Phenomenon of secondary union in which myofibroblasts at the edges of the wound contract & significantly reduce the area of the wound that must be filled with granulation tissue & subsequent scar
internal (primary) callus
Reunites the edges of the bone fragments in areas that are well vascularized,
Immature woven bone develops from the peuripotential cells of the endosteum & the inner layer of the periosteum
external (bridging) callus
Stabilizes the fracture,
Fibrocartilagenous collar that is formed around the fractured edge of the bone which eventually fuses with a similar collar formed at the edge of other bone fragments
periosteum
The dense fibrous membrane covering the surface of bones except at the joints & serving as an attachment for muscles & tendons
endosteum
The thin layer of cells lining the medullary cavity of a bone
cortical bone
Dense & forms the surface of bone,
aka compact bone
trabecular bone
spongy & makes up the bulk of the interior of most bones, including the vertebrae,
Also known as cancellous bone
haversian canal
Any of the tiny, interconnecting, longitudinal channels in bone tissue through which blood vessels, nerve fibers, & lymphatics pass
volkman canal
Any of the various canals in bone that transmit blood vessels from the periosteum into the bone
osteon
Also called Haversian system,
Predominant structures found in some lamellar or compact bone
osteoid
Resembling bone,
The bone matrix, especially before calcification
woven bone
Bony tissue characteristic of the embryonic skeleton in which the collagen fibers of the matrix are arranged irregularly in the form of interlacing networks,
aka nonlamellar bone, reticulated bone,
**Always the result of a pathologic condition if present in an adult
lamellar bone
Any bone with a microscopic structure consisting of thin layers or plates
wolff law
The principle that every change in the form & the function of a bone or in the function of the bone alone, leads to changes in its internal architecture & in its external form
pseudoarthrosis
The formation of a false joint caused by the failure of the bones to fuse
non-union
The failure of a fractured bone to heal normally
