Chapter 2 - Inflammation & Repair Flashcards
Which of the following is the body’s initial response to injury?
A. Immune response
B. Inflammatory response
C. Repair and regeneration
D. Hyperplasia and hypertrophy
B. Inflammatory response
What type of inflammation occurs if the injury is minimal and brief, as well as the source being removed from the tissue?
Acute
During the inflammatory response, the FIRST microscopic event is:
A. Dilation of the micro circulation
B. Increased permeability
C. Formation of exudate
D. Constriction of the micro circulation
D. Constriction of the micro circulation
The direct movement of white blood cells to the area of injury is called:
Chemotaxis
Which of the following cells are the most prevalent in CHRONIC inflammation?
A. Neutrophils
B. Macrophages and lymphocytes
C. Lymphocytes and plasma cells
D. Neutrophils and lymphocytes
C. Lymphocytes and plasma cells
What is the function of the macrophage?
Phagocytosis
What term is used to describe blood plasma with cells and proteins that leaves the blood vessels and enters the surrounding tissue during inflammation?
Exudate
The process of phagocytosis during inflammation DIRECTLY involves the
Ingestion of foreign substances by white blood cells
Which of the following statements is INCORRECT concerning the neutrophil?
A. Neutrophils make up 30% of WBCs
B. Neutrophils contain lysosomal enzymes
C. The neutrophil is a cell whose main function is phagocytosis
D. The neutrophil has a multilobed nucleus
A. Neutrophils make up 30% of WBCs
During the process of inflammation, the second type of white blood cell to emigrate from the blood vessel into the injured tissue is the:
Macrophage
Components of the complement system mediate the inflammatory process by:
A. Decreasing vascular permeability
B. Releasing histamine granules from neutrophils
C. Causing cytolysis of cells
D. Decreasing phagocytosis
C. Causing cytolysis of cells
2 days after injury, granulation tissue can be described as:
Immature vascular connective tissue
The enlargement of superficial lymph nodes that occurs as a systemic sign of inflammation is:
A. Called leukocytosis
B. Regulated by the hypothalamus
C. Caused by changes in their lymphocytes
D. A process that involves only the lymph nodes in the sub mental area
C. Caused by changes in their lymphocytes
Which statement concerning repair in the body is considered true?
A. Repair can be completed with the injurious agents present
B. Functioning cells and tissue components are always replaced by functioning scar tissue
C. Repair always results in regeneration
D. The process of repair is initiated by the inflammatory response
D. The process of repair is initiated by the inflammatory response
The clot that forms during repair after injury
Serves as a guide for migrating epithelial cells
Healing by secondary intention refers to healing of an injury when:
There is increased formation of granulation tissue
An increase in the size of an organ or tissue resulting from an increase in the number of its cells
Hyperplasia
Bone tissue repair in the body can be delayed by:
A. Maintenance of osteoblast producing tissue
B. Inadequate movement of bone tissue
C. Drainage of an area of edema
D. Reduction in the amount of tissue infection
B. Inadequate movement of bone tissue
What type of healing is present when there is little loss of the tissue?
Healing by primary intention
What cells are similar to smooth muscle cells and help the healing site contract?
Myofibroblasts
Which of the following directly allows for the presence of fever?
A. Production of bone tissue
B. Wound healing
C. Presence of pyrogens
D. Production of C-reactive protein
C. Presence of pyrogens
Hyperemia is directly responsible for which two local clinical signs of inflammation?
Erythema and heat
Which of the following lesions is noted for a microscopic grouping of macrophages usually surrounded by lymphocytes?
A. Lymphoma
B. Granuloma
C. Keloid
D. Abscess
B. Granuloma
Which of the following lesions would clinically appear as a pigmented lesion?
A. Amalgam tattoo
B. Traumatic ulcer
C. Frictional keratosis
D. Aspirin burn
A. Amalgam tattoo
