Muscles & Movement (Human Biology II)

DESCRIPTION

This course describes why humans see, touch, smell, taste and hear the world around us like we do. It also shows with practical examples how our body is able to move and how to improve flexibility, performance and posture. The course guides you to a better understanding of the operation of muscles and nerves, in movements and reactions observed in the body.

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

Suggested Prior Learning: Human Biology BSC101 or equivalent.

LESSON STRUCTURE

There are 8 lessons in this course:

1. How Nerves Work
2. Nerves & Motor Skills
3. Skeletal Muscle
4. Muscle Organisation
5. Muscular Movement
6. Muscular Development
7. Muscle Flexibility
8. Muscles & Posture

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.
