There are two ways a muscle contraction can be graded‚ either by changing the frequency of stimulation or by changing the strength of the stimulation.

The skeletal muscles are made up of bundles of muscle fibres (which are also known as myofibrils‚ as can be seen below). Each of the muscle fibres contain many sarcomeres‚ which is the most basic form of striated muscle tissue- they consist of two

Stimulus-Dependent Lab A motor unit is a motor neuron and the muscle fiber it controls. A whole muscle is made up of hundreds of motor units that are handled by different motor neurons that react at different levels of stimulation. The electric shock acts as an action potential by changing the membrane permeability allowing the sodium and potassium ions to pass through. At different levels of stimulation the motor neurons stimulate a motor unit and the more stimulation the more motor units become
