Question	Answer
Bone (osseous tissue)	Composed of: cells in lacunae and calcium salts. Stores: CA and other minerals Makes: Blood cells Used to: Support/protect body
Hyaline cartilage	Made of: Abundant collagen fibers & rubbery matrix Located: Nose, end of long bones, trachea (gristle) Most common cartilage! Entire fetal skeleton is made of this!
Fibrocartilage	Highly compressible (tensile strength absorbs shock) Collagen fibers run parallel Example: forms cushion-like discs between vertebrae
Elastic Cartilage	Provides elasticity Example: supports the external ear
Dense Connective Tissue	Fibroblast cells Matrix element: made of collagen fibers Dense Reg. withstands stress from 1 direction Dense Irreg: stress from many directions
Areolar connective tissue	Location: Mostly in connective tissue Contains: All 3 fiber types in gel-like matrix Soft pliable tissue Can soak up extra fluid
Adipose tissue (fat)	Matrix: is an areolar tissue Cells: contain large liquid deposits Functions: Insulates the body, protects some organs, & serves as a site of reserve fuel storage
