This course covers: nerves, the nervous system, motor skills, structure & function of skeletal muscle, muscular strength, endurance and flexibility.

COURSE STRUCTURE

There are 8 lessons as follows:

  1. How Nerves Work - how nerves cause reactions in the human body.
  2. Nerves & Motor Skills - how the nervous system affects motor skill performance
  3. Skeletal Muscle - function and structure of skeletal muscle in the human body
  4. Muscle Organisation - organisation of muscle tissue in the human body
  5. Muscular Movement - mechanics of muscular movement
  6. Muscular Development - development of muscular strength and muscular endurance.
  7. Muscle Flexibility - selecting muscular flexibility exercises
  8. Muscles & Posture - significance of muscles to posture and general well being.

Each lesson culminates in an assignment which is submitted to the school, marked by the school\'s tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.

  • Explain activity at muscle-nerve junctions, during the specific body movement.
  • Explain how proprioceptors function, during the specific body movement.
  • Explain processes which occur in the nervous system, when a specific muscle moves.
  • Explain the functioning of the following different sensory receptors:
    • smell
    • sound
    • balance
  • Distinguish between the functions of the following different neuroglia:
    • Astrocytes
    • Oligodendrocytes

  • Explain the dampening affect, as exerted through the cerebellum.
  • Explain how the body perceives speed through the nervous system.
  • Explain the operation of tendons, during a specific movement of a limb.
  • Compare the function of motor with sensory fibres in nerves supplying muscles.
  • Compare differences in the structural characteristics of red and white muscle fibres.
  • Summarise events occurring during muscular contraction, at a microscopic level.
    • Explain how muscles of the hand move when you pick up a tennis ball.
      • Prepare diagrams showing the muscles in the back which provide both support and movement for the spinal column.
      • Explain the significance of these muscles to health, wellbeing and mobility.
      • Explain the principle of levers related to an observed muscular movement.
      • Explain the principle of moments related to an observed muscular movement.
      • Explain muscular movements which occur in the observed subjects, when using three different types of exercise machines.
      • Explain three different body movements, in terms of the action of different bones, muscles and nerves; including the movement of a limb in exercise, and the bending of the back, and one hand movement.
      • Distinguish between isotonic, isometric, eccentric and isokinetic contractions.
      • List ways how strength can be maintained and increased.
