III - Tissue Repair, Healing and Fibrosis Flashcards
Cells of these tissues are continuously being lost and replaced by maturation from stem cells and by proliferation of mature cells. Can readily regenerate after injury as long as the pool of stem cells is preserved.
Labile tissues(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.61
Cells of theses tissues are quiescent and have only minimal replicative activity in their normal state. Capable of proliferating in response to injury or loss of tissue mass.
Stable tissues(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.61
Cells of these tissues are considered to be terminally differentiated and nonproliferative in postnatal life.
Permanent tissues(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.62

Permanent(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.62
Type of collagen found in basement membrane
Type IV collagen(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.67
This is the most abundant glycoprotein in basement membrane.
Laminin(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.68
The pink, soft, granular tissue seen beneath the scab of a skin wound.
Granulation tissue(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.70
Maturation and reorganization of fibrous tissue
Remodeling(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.70
Healing of a clean, uninfected surgical incision approximated by surgical sutures
Healing by first intention / Primary Union(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.74
Type of healing wherein tissue is allowed to heal by itself before suturing. Used in large wounds, in the presence of abscess, or ulceration.
Healing by secondary intention / secondary union(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.76
Wound strength reaches 70 - 80 % of normal in ______ months.
3 months(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.77
Single most important cause of delay in wound healing.
Infection(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.77
True or false: Complete restoration can occur only in tissues composed of stable and labile cells.
True(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.77
Refers to the restoration of tissue architecture and function after an injury.
Repair (TOPNOTCH)Robbins Basic Pathology, 8th ed. p.77
True or false:Injury to tissues composed of permanent cells does not result to scarring.
False. Injury to tissues composed of permanent cells, inevitably results to scarring.(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.77
Process of replacing damaged components of a tissue, returning to a normal state.
Regeneration (TOPNOTCH)Robbins Basic Pathology, 8th ed. p.77
Migration and proliferation of fibroblasts with deposition of ECM.
Scar formation(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.72
Maturation and reorganization of fibrous tissue
Remodeling(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.73
Arrange the steps in cutaneous wound healing:A. Formation of granulation tissueB. ECM remodelingC. Inflammation
C, A, B(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.72
It consists of a series of steps at which the cell checks for the accuracy of replication and mitosis and instructs itself to proceed to the next step.
Cell cycle(TOPNOTCH)Robbins Basic Pathology, 8th ed. p.61
In the cell cycle, this is called the presynthetic growth phase.
