Connective Tissue Flashcards
4 Main types of Tissue
Epithelium, Connective tissue, Muscle and Nervous tissue
Predominating component of CT
intercellular substance
glycoproteins or glycosaminoglycans, a gel like that fills the spaces between the fibers and cells
ground substance
medium through which O2, nutrients and
by-products diffuse
ground substance
can be collagen, reticular or elastic fiber
fibers
fibers can be
can be collagen, reticular or elastic fiber
normal cellular constituents of c.t.
resident cells
how many resident cells
8
stellate or spindle shaped with cytoplasmic processes; cells of the embryo which transform into different types of adult cells as development progresses
mesenchymal cells
most common resident cells of loose c.t.; shape of the cells depend on their
location in the c.t.
fibroblasts
in tendons and ligaments, fibroblasts are
elongated and fusiform
in loose c.t. , fibroblast is in
rounded form
produce _, _ and _ aside form the amorphous
ground substance
collagen, elastic and reticular
fibers
similar in form with the mesenchymal cells;
reticular cells
mainly found in lymphatic organs where they produce reticular fibers;
reticular cells
also called histiocytes or clasmatocytes –have varied shape
macrophages
when crowded by other tissue components-they are ___
angular
their nucleus is __ and indented on one side of the cell;
bean shaped
in loose c.t. , macrophages are __ with bean or indented nucleus
rounded
cytoplasm contain granules (believed to be
__)
lysosomes
macrophages are derived from the _____ and they have phagocytic function
mesenchymal cells or monocytes
size and shape vary greatly in different animals even within the same species
mast cells
nucleus rounded, ____ in placement
central to eccentrical
granules contain ___ and ___ that cause inflammation (allergy)
heparin and histamine
large multinucleated cells
foreign body giant cells
FBGC are formed from the fusion of _____
monocytes or macrophages
white and brown adipose cells
fat or adipose cells
white adipose cells which appear like a ___ with a nucleus bulging slightly from one side of the ring/cell
signet ring
in tissue section, adipose cells appear
___ because the fats are dissolved by
alcohol during processing;
empty
in tissue section, adipose cells appear
empty because the fats are dissolved by
__ during processing;
alcohol
characterized by numerous fat droplets thus, called multilocular
brown adipose cells
numerous fat droplets thus, called
__
multilocular
