3
name the 3 types of fibers
collagen
elastic
reticular
what are the properties of collagen fibers
very strong and flexible
what are the properties of elastic fibers
smaller stretch and return to original length
what are the properties of reticular fibers
form a mesh
provides support and strength
found in basement membranes and organ support
name the types of loose connective tissue
areolar
adipose
reticular
what are areolar cells
cells embedded in a matrix of glycoproteins, elastin and collagen fibers
what are adipose cells
cells filled with fat droplet
what are reticular cells
mesh of reticulin fibers

dense regular
dense irregular
elastic
