Definition
-19 types
-1 to 4 are common
-type on is typical
-acidophilic
Term
15)Elastic Fibers
Definition
-made of elastin ( composed of fibrillin)

Term
17)reticular fibers
Definition
-type 3 collagen
-thing, silver salts stain
-in lymph and spleen
-compose the reticular lamina, below basal lamina
Term
