14. Fashion Parade  You will be given a movement that you have to demonstrate while walking up the cat walk  Make sure you state what joint we are looking at!

15. Muscles work in pairs  When one muscle is working the other is relaxed. We use the following terms to explain what each muscle is doing:  Agonist = is the working muscle  Antagonist = is the oppostie muscle which is not working (ie relaxed)

16. Agonist = biceps Antagonist = triceps Agonist = triceps Antagonist = biceps biceps triceps

17. MUSCLES MuscleMain Action DeltoidShoulder abduction, flexion and extension PectoralsShoulder adduction and flexion Latissimus DorsiShoulder adduction and extension

27. How Muscles Work Together  What Prevents Hyperextension?? The contraction at the end of the movement by our muscles.. i.e.. In knee extension the hamstrings would contract at the end of the movement to slow/control the extension

28. How Muscles Work Together  Flexion is when the angle between the bones decrease and extension is when the angle between the bones increase. The bones involved in the movement at the knee joint are the femur, tibia, fibula, and patella. The hamstrings and quadriceps work together to produce the flexion and extension at the knee. The hamstrings are the prime mover (agonist) for flexion at the knee and contracts to produce the movement. The quadriceps relax to allow flexion to occur then contract towards the end of the movement to slow the extension
