Presentation Transcript

  1. Movement Conscious and unconscious movements- how we move and how we control those movements

  2. Movement • Any movement within your body, either conscious or not, in response to a stimulus from the external environment or from a need noticed inside your body • Voluntary movement- movement of skeleton • Involuntary movement- digestion, heartbeat, breathing

  3. Systems involved • Skeletal system • Provides structural support for body • Muscular system • Moves bones (and others) to put body into desired positions

  4. Types of muscle • Skeletal Muscle- attached to bones- directly moves body parts • Smooth Muscle- line many organs- involuntary • Cardiac Muscle- only in heart- pumps heart

  5. Movement of your skeleton- Connections • Tendons- connect muscle to bone • When muscle contracts, pulls bone • Ligaments- bone to bone • Holds bones together

  6. Tying it all together • Cellular Respiration • Takes oxygen and glucose, makes ATP • ATP used to make muscles contract • Muscles and other organs we’ve discussed • Lungs/diaphragm • Intestines/smooth muscle lining

  7. Cellular Respiration • In Mitochondria • Glucose broken down • Bonds in glucose turned into ATP • Useable energy • Remaining carbon from glucose exhaled as carbon dioxide

  8. Organs relying on muscles • Intestines • Muscles contract to cause food to be pushed through • Blood vessels/capilaries • Muscles contract to open/close blood vessels

  9. Procedures that help you • ACL/MCL surgery • Rotator cuff • “Tommy John” procedures

  10. ACL/MCL Surgery • Ligaments • Anterior cruciate and Medial Collateral Ligaments • Similar to rubberbands that holdbones together

  11. Rotator Cuff • Group of muscles and tendons that hold shoulder in place • With overuse or trauma, tendons can tear • To fix, must drill holes in bone to restring tendons (often taken from hamstring area)

  12. Tommy John • Baseball pitcher • Through repetitive twisting of elbow, frayed UCL (ulnar collateral ligament) • Elbow surgery done to replace ligament with tendon taken from somewhere else in body

  13. Diseases involving movement • MS vs. ALS • Tendinitis

  14. MS vs. ALS • MS attacks all neurons • ALS attacks only motor neurons • Immune system attacks nerves, preventing signal from being sent to muscles telling person to move

  15. Tendinitis • Inflammation of tendons • Due to overuse of tendon OR • Due to acute injury
