Connective Tissue Flashcards
It is fixed and transient
Cells
Examples are ground substance and fibers
Extracellular matrix
Examples of this are GAG, proteoglycans, glycoproteins
Ground substance
Examples of this are Collagen and elastic
Fibers
Under fixed cells
Fibroblasts
Adipose cells
Pericytes
Mast cells
Macrophages
Under transient cells
Plasma cells,
lymphocytes,
neutrophils,
eosinophils,
basophils,
monocytes,
macrophages
The most abundant cell type in the connective tissue, are responsible for the synthesis of almost all of the ECM
FIBROBLASTS
Are modified fibroblast that demonstrate characteristics similar to those of both fibroblasts and smooth muscle cells
MYOFIBROBLAST
Absence of basal lamina
MYOFIBROBLAST
Abundant in areas undergoing wound healing
MYOFIBROBLAST
Surround endothelial cells of capillaries and small venules and reside outside the connective tissue compartment, because they possess their own basal lamina
PERICYTES
Are fully differentiated cells that function in the synthesis, storage and release of fats
ADIPOSE CELLS
Single, large lipid droplet
White adipose tissue (unilocular fat cells)
Multiple, small lipid droplets
Brown adipose tissue (multilocular fat cells)
Arise from bone marrow stem cells and function in mediating the inflammatory process and immediate hypersensitivity reactions
MAST CELLS
Macrophages belong to the mononuclear phagocytic system and
are subdivided into two groups of cells:
Phagocytes
Antigen-presenting cells APC
Act both as fixed and transient cell
MACROPHAGES
Hydrated, amorphous material that is composed of GAG, proteoglycans and glycoproteins
Ground substance
Collagen and Elastic
Fibers
