Summation and tetanus
WebFused tetanus is when there is no relaxation of the muscle fibers between stimuli and it occurs during a high rate of stimulation. A fused tetanic contraction is the strongest single-unit twitch in contraction. When tetanized, the contracting tension in the muscle remains constant in a steady state. This is the maximal possible contraction. WebMotor unit summation or spatial summation is. the recruitment of additional motor units within a muscle to develop more force. . Motor unit summation occurs until sufficient force is developed within the muscle to move a load. A maximum contraction is generated when all the motor units are activated within a muscle.

WebDuring a tetanus, on the other hand, the activity of the contractile elements is maintained, and they can eventually shorten enough to extend fully the series of elastic elements. When this has been accomplished, the maximum tension is apparent at the ends of the muscle. Length-tension relationship WebThe whole principle of summation depends on the fact that the action potential duration (and its refractory period) is much shorter than the duration of the ensuing contraction. …
