Concept of tissue repair and wound healing

Question 1

it overlaps the inflammatory process

response to tissue injury and represents an attempt to maintain normal body structure and function

Answer 1

Tissue repair and healing

Question 2

Tissue repair and healing can occur in 3 ways

Answer 2

resolution
regeneration
replacement

Question 3

is the process that occurs when there is minimal tissue damage

Answer 3

resolution

Question 4

is the process that occurs in damaged tissue in which the cells are capable of mitosis

Answer 4

regeneration

Question 5

the process that occurs when there is extensive tissue damage or the cells are incapable of mitosis, injured cells are replaced with connective tissue which leaves a permanent scar (fibrous tissue repair)

Answer 5

replacement

Question 6

Both organs and tissues are composed of 2 types of structures

Answer 6

Parenchymal tissue

Stromal tissue

Question 7

contains the functional cells of an organ or body part.

Answer 7

Parenchymal tissue

Question 8

Body cells are divided into 3 types and undergo regeneration

Answer 8

labile
stable
permanent cells

Question 9

consists of supporting connective tissues, blood vessels, extracellular matrix and nerve fibres

Answer 9

Stromal tissue

Question 10

> Regeneration is limited to tissues with cells that are able to undergo mitosis
seen in mild to moderate injury
occurs when damage is limited to parenchymal cells
involves replacement of injured tissue with the cells of the same type (leaving little evidence of previous injury)

Answer 10

Tissue regeneration

Question 11

Capacity of regeneration varies with the tissue and cell type; Body cells are divided into 3 types according to their ability to undergo regeneration

Answer 11

Labile cells
Stable cells
Permanent or fixed cells

Question 12

cells that continue to divide and replicate throughout life, replacing cells that are continually being destroyed

include:
> surface epithelial cells of skin, oral cavity, vagina, cervix
> columnar epithelium of GI tract, uterus, fallopian tubes
> transitional epithelium of urinary tract
> bone marrow

Answer 12

Labile cells

Question 13

cells that normally stop dividing when growth ceases. These cells are capable of undergoing regeneration when confronted with an appropriate stimulus and are capable of reconstituting the tissue of orogin

include:
> parenchymal cells of liver and kidney
> smooth muscle cells
> vascular endothelium cells

Answer 13

Stable cells

Question 14

cells that cannot undergo mitotic division. These do not regenerate, once destroyed are replaced with fibrous scar tissue that lacks the functional characteristics of the destroyed tissue

include:
> nerve cells
> skeletal muscle cells
> cardiac muscle cells

Answer 14

Permanent or fixed cells
