SKELETAL SYSTEM

FUN FACTS

• All bones produce red blood cells.
• There are 206 bones in a mature human’s body.
• Bones protect internal organs.
• Bones are made of collagen.

FUNCTIONS

• Support: provides framework that supports and anchors all soft organs.
• Protection: skull and vertebrae surround soft tissue of the nervous system,and the rib cage protects vital thoracic organs.
• Movement: skeletal muscles use the bones as levers to move the body.
• Storage: fat stored in the interior of the bone . Bone matrix serves as a storehouse for various minerals.

• The skull protects the brain
• All bones store and release fat
• All bones produce red blood cells
• Bones support the body by keeping our body stable. This most importantly includes the spine.

THE SKELETON CAGE

• The bones act as a “cage” for the bodies organs.
• They protect the internal organs from getting damaged.
• For example: the rib cage is a barrier built around the lungs, to protect the lungs from puncture.

• Some bones are connected to ligaments and joints.
• Ligaments:connect the end of bones together in order to form a joint.
• Joint:structures that connect individual bones and may allow bones to move against each other to cause a movement

DISORDERS AND DISEASES

• Osteoporosis:this is a disease in which the bones become fragile and prone to fracture.
• Leukemia:this is a cancer of the white blood cells.
• Osteopenia, osteitis deformans, and osteomalacia: similar to osteoporosis, these are other types of bone loss.
• Osteogenesis imperfecta: a rare hereditary disease of connective tissue characterized by brittle bones that fracture easily

• Diseases and injuries of bones are major causes of abnormalities of the human skeletal system.

KEEPING YOUR BONES HEALTHY

• Eat calcium;choose dairy products, fish with bones like salmon.
• Don’t smoke or drink heavily.

Untitled Slide

• Eat foods with vitamin D
• Exercise or stretch at least 30 minutes a day.
• Protect your bones by wearing a seat belt when you are in the car, and a helmet while riding a bicycle.
