اسلاید 4: Functions of Skeletal SystemSUPPORT: Hard framework that supports and anchors the soft organs of the body.PROTECTION: Surrounds organs such as the brain and spinal cord.MOVEMENT: Allows for muscle attachment therefore the bones are used as levers.STORAGE: Minerals and lipids are stored within bone material.BLOOD CELL FORMATION: The bone marrow is responsible for blood cell production.

اسلاید 9: StructureCompact boneOuter layer of bone, very hard and dense.Organized in structural units called Haversian systems.Matrix is composed of Ca salts (Ca carbonate and Ca phosphate)Osteocytes – living bone cells that live in matrix.Porous (Spongy) boneLocated in the ends of long bones.Many spaces that are filled with red bone marrow which produces bone cells.
