Musculoskeletal System The Musculoskeletal System consists of : Bones Joints Ligaments Cartilage Muscles
Musculoskeletal System MUSCULOSKELETAL = two words musculo + sketetal musculo- = means muscles -sketetal = means skeleton (Bones) 206 bones Muscles Skeleton
Skeleton Function Supports the body Provides framework for the body Gives shape to the body Protection Protects vital organs Protects soft tissues Movement Provides locomotion (walking, movement) by attachment of muscles, tendons, and ligaments Hematopoiesis Produces red blood cells Produces white blood cells Produces platelets Storage Provides calcium Provides phosphorus Support SKELETON
2) Appendicular Skeleton: Consists of bones of the limb girdles and limbs.
Diseases and Disorders of the bones 1. Osteoporosis Metabolic disorder of bones Less bone mineral (calcium) than normal Over 10 million in US affected Post-menopausal females most commonly Bones are brittle, porous, easily broken More prone to pathological fracture
Diseases and Disorders of the bones 2. Fractures is a break in the continuity of the bone. Caused by high force stress Closed/simple Open/compound
