Understanding the Skeletal & Muscular Systems: Functions & Interconnections

Explore the functions of the skeletal & muscular systems in the human body, from bones to muscles and their crucial roles in movement, support, and protection. Learn about ligaments, joints, tendons, and the interconnection with other bodily systems. Discover the different types of muscles and their functions. Gain insights on how the skeletal and muscular systems coordinate with other bodily systems for optimal function.

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
