- - - - The part of a lever system that pivots joint are the fulcrums in the body's lever systems
    - - The lead to be moved by a lever system usually this involves might when the body's lever system are involves
    - - The force applied to move the resistance or wight in the body the effort is provided by the muscles exerting a force
    - - Found at the elves joint where the triceps causes extension of the lower arm
    - - Found at the ankle where the gastrocnemius causes planter flexion
    - - The majority of the body's joints act as third class levers for example the biceps acting at the elbow to care flexion acts as a third class lever system
- - - - Muscle action where the muscle changes length causes movement
    - - Muscle action where the muscle stays the same length used in balances
    - - Isotonic contraction where the muscle shortens
    - - Isotonic contraction where the muscle lengthens used to control downward movements
    - - The prime mover muscle that causes movement
    - - Muscle that relaxes to allow the agonist to contract
    - - Attach muscles to bones
- - - - Plane and axis for forwards and backwards movements direction for extraction and flection
    - - plane and axis for side to side movements direction for abduction and adduction
    - - Plane and axis for rotation movements direction for rotations and spins
- - - - muscle causing flection at the shoulder
    - - Muscle causing extension at the shoulder
    - - Muscle causing flexion at the elbow
    - - Muscle causing extension at the elbow
    - - Group of muscles causing flexion at the knee
    - - Group of muscles causing extension at the knee
    - - Main agonists at the hip during hip flexion
    - - Main agonists at the hip during hip extension
    - - Muscle causing dorsiflexion at the ankle
    - - Muscle causing plantar flexion at the ankle
    - - Group of muscles causing rotation at the shoulder
