Muscles & Movement (Human Biology II)

Enhance your career with more in depth knowledge on why humans see, touch, smell, taste and hear the world around us like we do. The course also shows with practical examples how our body is able to move and how to improve flexibility, performance and posture.

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.
