is voluntary), Cardiac (makes up the bulk of the heart muscle and is involuntary) and Smooth (located on the walls of internal structures eg stomach, intestines and is primarily involuntary)

Define Origin and Insertion - answer Origin - The muscle's point of attachment to the more stationary bone is called its origin. In most cases, this point is nearer the trunk
Insertion - The insertion of a muscle is the point of attachment at the moveable end. This end tends to be away from the body's main mass.
Name the 3 muscle actions - answer Agonist - An agonist or prime mover (shortens) is the muscle causing the major action.
Antagonist - An antagonist is a muscle that must relax and lengthen to allow the agonist to contract.
Stabiliser - Or fixator muscles act at a joint to stabilise it, giving the muscles a fixed base.
