The cells that produce collagen in response to TGF-β stimulation may vary depending on the tissue. In most organs, such as in the lung and kidney, myofibroblasts are the main source of collagen,which cells are main collagen producers in liver cirrhosis? 

Stellate cells

Primordial cells

Hyperplasia cells

Cribriform cells

Which of the following cells are quiescent with minimal baseline proliferative activity? *

Kidney cells

Cardiomyocytes

Skin cells

GI tract cells

Which type of ulcers develop in individuals with atherosclerosis of peripheral arteries, especially associated with diabetes? 

Arterial ulcers

Pressure ulcers

Venous leg ulcers

Diabetic ulcers

If the scar tissue grows beyond the boundaries of the original wound and does not regress, it is called a: 

Keloid

Contracture

Proud flesh

Hypertrophic scar

One of the most important causes of delayed healing is: *

Infection

Good Perfusion

Non-diabetic

Good nutritional status

TGF-β is involved not only in scar formation after injury but also in the development of fibrosis in lung, liver, and kidneys that follows chronic inflammation. TGF-β also has anti-inflammatory effects that serve to limit and terminate inflammatory responses. It does this by: *

Inhibiting lymphocyte proliferation

Promoting lymphocyte proliferation

Will causes recruitment of B Lymphocytes

Promoting phagocytosis of all the debris

Wound contraction is an important part of the normal healing process. An exaggeration of this process gives rise to : *

Proud Flesh

Keloid

Contracture

All of these

Mechanical factors such as increased local pressure or torsion may cause wounds to pull apart, this is called : 

Wound Dehiscence

Hypertrophic scar

Keloid

Sclerosing Adenosis

Granulation tissue is characterized by: *

proliferation of fibroblasts

new thin-walled, delicate capillaries in a loose extracellular matrix

admixed inflammatory cells, mainly macrophages

All of these

Marrow hematopoietic cells are: *

Labile cells

Stable cells

Permanent cells

None of these

Terminally differentiated nonproliferative cells, such as the majority of neurons and cardiac muscle cells are called : 

Stable cells

Neoplastic cells

Permanent cells

Labile cells

An 18-year-old man lacerated his left hand and required sutures. The sutures were removed 1 week later. Wound healing continued, but the site became disfigured by a prominent raised, nodular scar that developed over the next 2 months. Which of the following terms best describes the process that occurred during this 2-month period? *

Dehiscence

Organization

Keloid formation

Resolution

Carefully see the picture and give your provisional diagnosis. *

Keloid

Hypertrophic scar

Proud flesh

All of these

A cesarean section is performed on a 20-year-old woman to deliver a term infant, and the lower abdominal incision is sutured. The healing of a clean uninfected wound is called: *

Healing by first intention

Secondary union

Healing by second intention

All of these
