Key words
• Origin and insertion of muscles • The origin is the end of a muscle which is
attached to a fixed bone. • The insertion is the end of the muscle that is
attached to the bone which moves.

Antagonist vs Agonisthttp://www.youtube.com/watchv=rAz2Pam73e0
Know your definitions
Agonist: The agonist or prime mover is the muscle causing the major action.
Antagonist: An antagonist is a muscle that must relax and lengthen to allow the agonist to contract, thus helping to control an action. The agonist works as a pair with the antagonist muscle. The two roles are interchangeable depending on the direction of the movement.
Fixator/Stabiliser: stabiliser or fixator muscle act at a joint to stabilise giving the muscles a fixed base.
Synergist: A muscle which aids the action of a prime mover (a muscle which has the main responsibility for a particular movement). The synergist may produce the same movement as the prime mover, or it may stabilize the joints across which the prime mover acts, preventing undesirable movements

Types of Contractions• Concentric – during this contraction, the
muscle shortens, causing the movement at the joint
• Eccentric – contraction occurs while the muscle lengthens under tension
• Isometric- contraction occurs when the muscle fibres are activated and develop force, but the muscle length does not change; that is, movement does not occur.
