LABORATORY REPORT Activity 2: Twitch Contractions and Summation PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: contraction force increases‚ becoming maximum at an optimal length‚ then decreasing at longer lengths. Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases‚ the force of contraction: increases. MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable: contraction force

Animals have three types of muscles; skeletal‚ smooth‚ and cardiac. This lab however is only concerned with skeletal muscle. A special characteristic of skeletal muscle is their ability to contract or shorten via thin (actin) and thick (myosin) filaments (Flanagan‚2017). This gives a striated appearance which is a key distinguishing characteristic between other types of muscle (Flanagan‚2017). Skeletal muscle is also multinucleated. Skeletal muscle needs plentiful amounts of energy to be able to

The first phase is called Interphase. In interphase there are

It is unimaginably frightful for people around me and even worse for me. It interests me‚ my anger‚ and it makes me wonder what a human being is capable of‚ what lengths a certain emotion
