Presentation Transcript

  1. Skeletal & Muscular System

  2. Function: • The skeletal system …. • Holds the body up (structure and shape) • Protects internal organs • Helps the body move • Stores minerals, Calcium, Phosphorus • Makes blood cells

  3. PART 1: BONES • -make up the skeletal system • Made of living cells and protein fibers • - Produce blood cells in the bone marrow • - 206 bones in adult body • - 300 bones in infant (later fuse together)

  4. PART 2: CARTILAGE • - Softer and more flexible than bone • - gives shape • Connects the bones • Supports the body

  5. Do Now! What are 3 things you learned from the muscle lab? EXPLAIN how proof (DATA) from a lab station led you to learn this?

  6. PART 3: LIGAMENTS • Connects bone to bone • holds bones together at the joints • 900 ligaments in human body

  7. PART 4: JOINTS • where 2 or more bones connect together • Allow movement

  8. PART 5: TENDONS • tough connective tissue that • connects bone to muscle

  9. MUSCULAR SYSTEM

  10. Muscular System Function The muscular system… -helps you move -helps move blood through the body (arteries/veins/capillaries) -pumps your blood (heart) -helps you breathe (lungs) -moves food through digestive system (stomach, intestines)

  11. TYPES OF MUSCLE • Smooth Muscle • tissue in walls of organs, arteries, veins • In the stomach, lungs, and other soft internal organs • Involuntary movement (moves by itself) • Controls the way blood flows through circulatory system

  12. TYPES OF MUSCLE • Skeletal or Striated Muscle: • attached to legs, arms, back, and torso • Helps to move bones • Voluntary movement

  13. TYPES OF MUSCLE • Cardiac Muscle: • - only in the heart • involuntary movement (moves by itself)

  14. CONNECTION TO THE SYSTEMS • Skeletal and muscular system work together to help you move • Muscular system works with circulatory system to pump blood through the body • Muscular system works with digestive system to move food through digestion • Muscular system works with respiratory system to exchange gases • Muscular system works with excretory system to eliminate waste • Nervous system controls skeletal and muscular system
