Week 2 Flashcards
Antibody-producing cells are called:
Plasma Cells
What are the two main components of extracellular matrix?
Ground Substance and Protein Fibers
The type of connective tissue proper immediately adjacent to the epithelium (e.g. the papillary layer of skin) is most likely to be:
Loose connective tissue
The dermis of the skin contains which type of connective tissue proper?
Dense irregular connective tissue
The connective tissue that is found in a tendon is:
Dense, regular
What condition is produced by increased blood flow and vascular permeability?
Edema
Which type of fibers are tendons composed of?
Collagen
One major function of connective tissue proper is to physically support and connect other tissues. A second major function is to
Maintain water as interstitial fluid for nutrient and metabolite diffusion, using hydrostatic and osmotic pressure.
The connective tissue cell that promotes an allergic response by releasing chemicals like histamine is the
Mast cell
All of the following are connective tissues EXCEPT ONE. Which one is the EXCEPTION?
Muscle
What is the function of mucoid connective tissue?
Protection of blood vessels in the umbilical cord.
What do these cell types have in common: Microglia, osteoclasts, and Kupffer cells?
They are part of the mononuclear phagocyte system.
Collagen synthesis is a product of which of the following cells?
Fibroblasts
The formation of scar tissue following surgery or wounding is largely due to
Fibroblasts
The two major types of protein fibers in the ECM are
Collagen and elastic
What is interstitial fluid?
It is water in the ground substance of connective tissue.
Reticular fibers are made of type III collagen. They function as a supportive stroma in which organs/glands?
Endocrine glands, Lymphoid organs, Hematopoietic organ
The largest and most unique GAG (glycoaminoglycan) is:
Hyaluronic acid (hyaluronan)
In the presence of an allergen (which can from any of a number of things such as insect venom, peanuts, penicillin, etc.), release of certain chemicals from mast cells may promote an allergic reaction known as an immediate hypersensitivity (also called Type I hypersensitivity) reaction. How is this reaction different from the normal infectious immune response of mast cells?
The immediate hypersensitivity reaction typically requires a previous sensitization to the allergen.
The connective tissue cell whose role is to phagocytize debris around a wound is the
Macrophage
