Chapter 6 lecture 1

  1. 1. Chapter 6 The Muscular System Disclaimer: Included in this presentation are videos and pictures you will not find in your book, make note of the information and move on. Working smarter is not working harder.
  2. 2. Objectives <ul><li>The overview of the make up of the Skeletal Muscle system </li></ul><ul><li>Muscle: Functions, Anatomy & Physiology of a Muscle Contraction : Sarcomere </li></ul><ul><li>Nervous system connection to the Skeletal Muscle system : Large Scale </li></ul>
  3. 3. What do we already know? How Many types of Muscles are there? 3 How many are Voluntary? 1 Which one is it? Skeletal
  4. 4. Types of Muscles Cardiac: Mono-nucleated Involuntary Branched Connected with Intercalated Disks for synchronization of movement
  5. 5. Types of Muscles Smooth: Mono-nucleated Involuntary Non-striated Moves in waves called “PERISTALSIS” Real life: Not human of course
  6. 6. Types of Muscles Skeletal: Multi-nucleated Voluntary Striated Moves the Body (amongst other things) He “Stuffs”
  7. 7. Overview: Skeletal Muscles <ul><li>There are 650 muscles on average in the human body </li></ul><ul><li>Muscle groups always complement each other, one contracting = one relaxing </li></ul><ul><li>Ex. Biceps & Triceps, Back & Abdominals </li></ul><ul><li>Muscles need nerve impulses to make them contract. </li></ul>
  8. 8. So what does 650 muscles look like? Like this…
  9. 9. Functions of Muscles Movement Maintaining posture
  10. 10. Functions of Muscles Stabilizing Joints Generating heat
  11. 11. How does this relate to what we already know? Things Necessary for Life Chapter 1
  12. 12. Remember all these? M.R. B.G. D.R.E.M.
  13. 13. Things Necessary for Life <ul><li>Boundaries = something that separates the outside from the inside of the organism </li></ul><ul><li>Movement = for getting food and causing things in the body to move like blood in your veins </li></ul><ul><li>Responsiveness = reactions to stimuli </li></ul><ul><li>Digestion = breaking down food into useful energy to be used </li></ul><ul><li>Metabolism = all chemical reactions in the body </li></ul><ul><li>Excretion = getting rid of waste from the body </li></ul>
  14. 14. Things Necessary for Life cont. <ul><li>Reproduction = the ability to produce OFFSPRING </li></ul><ul><li>Growth = To increase in size. Typically by increasing the number of cells. </li></ul>
  15. 15. Complimenting Muscles Groups For One Muscle to contract Another muscle must relax The is how it is across the entire body. Now you try it: Head Back  Head Forward
  16. 16. Anatomy of a Muscle Largest  Smallest OR Outside  In (Which ever you prefer) Epimysium Perimysium Fascicle Endomysium Muscle Fiber
  17. 17. A Closer look at Muscle Fiber Largest  Smallest OR Outside  In (Which ever you prefer) Sarcolemma Myofibril Sarcomere Of Course you would ask “What is a Sarcomere?” Lets Turn the page and Find out
  18. 18. A Closer look at Muscle Fiber Welcome to the: Sarcomere The smallest unit of the Muscle system I will be expecting you to know. A Sarcomere is simply the space from Z-Disc  Z-Disc
  19. 19. You with me so far? We went from Muscle Belly Epimysium Perimysium Fascicle Endomysium Individual Muscle Fiber Sarcolemma Myofibril Sarcomere Biggest Smallest
  20. 20. Anatomy & Physiology of a Muscle Contraction: Sarcomere ~Hold Please~
  21. 21. Path of a Muscle Contraction: Large Scale Stimulus: Someone tickles you The signal is sent to the CNS (Central Nervous system) Action: You interpret the signal and send a signal to your muscles for reaction = you turn and punch them in the head. Interpretation of that signal = “Someone just tickled me” = Muscle contraction
  22. 22. So what did we cover? <ul><li>The Skeletal Muscle System is Voluntary </li></ul><ul><li>It is part of the Things Necessary for Life </li></ul><ul><li>From Largest to Smallest: What makes up a muscle </li></ul><ul><li>What a Sarcomere is and does during a muscle contraction </li></ul><ul><li>The involvement of CNS for muscle reaction and contraction. (generally speaking) </li></ul>
  23. 23. What’s to come Start of : Lab of Head and Neck Lab of Torso and Arm *if Head and Neck books are occupied* Lecture 2: Motor Neuron pathways and Body Movements
