Bones

solid network of living cells and

protein fibers that are surrounded by

deposits of calcium salts. A living tissue composed mainly of

mineral salts - calcium and

phosphorus.

Periosteum

tough layer of connective tissue

surrounding the bone.

Spongy Bone

houses the bone marrow, allow for

RBCs formation or erythropoiesis,

and allow bones to be less dense

and more light. It also allows

flexibility.

Compact bone

(also known as cortical bone) forms

the hard, dense outer layer of bones

which functions to primarily to

provide strength and protection to

bones.

Bone Marrow

a soft tissue within bone cavities

Haversian System (Osteon)

a network of tubes that contain blood vessels and—- mam cel ppt error

yellow marrow

made up primarily of fat cells

usually found in round bones.

red marrow

produces red blood cells, some

kinds of white blood cells, and cell fragments

called platelets.
