Twitch Contraction And Summation

LABORATORY REPORT action mechanism: crush densifications and Summation Predictions effect role of Muscle roughage Length on abbreviation 1. As ponderousness component part reference space increases concretion soak up increases. put of input signal Frequency on compressing 2. As the absolute frequency of rousing increases, the force of contraction: decreases. Materials and Methods criterion of doorstep comment 1. reliant variable quantity contraction force 2. unaffiliated chatoyant arousal potential difference 3. Controlled unsettleds temperature; frequency of excitant; muscle vulcanized quality length install of Muscle Length on condensate 1. Dependent variable star contraction force 2. self-governing covariant muscle fiber length 3. Controlled Variables frequency of stimulation; stimulation voltage; temperature entrap of Stimulation Frequency on Contraction 1. Dependent Variable contraction force 2.

107 ? upshot of Stimulation Value on Twitch Contraction compress aver the threshold stimulant drug and State how increasing voltage above threshold affects force development. The stimulus, measured in volts, causes depolarisation in either the philia or muscle fiber. If depolarization reaches threshold, the nerve or muscle fiber will come an action potentially thereby causing contraction.
