    1 motor neuron may stimulate 80 - 100 fibres or stimulate 1 - 2 fibres for specific movement.

    muscle usually works across a joint. it is attached to both the bones by strong cords called tendons,when the muscle contracts,usually just one bone moves

    Muscular contraction:- Muscle fibre recruitment. The nerve that goes to the muscle is called a MOTOR NEURON. Motor neurons are responsible for stimulating a number of muscle fibres - together they are called a MOTOR UNIT. When precise movement is required, 1 motor unit may stimulate only 1-2 fibres, e.g. movement of the eye. When gross movement is required, 1 motor neuron may stimulate 80-100 fibres, e.g. quadriceps muscle. The all or nothing principle of muscle contraction When an electrical impulse reaches a threshold, all muscle fibres of that unit contract maximally. It is not possible for a muscle fibre to contract partially - it's all or nothing.
