Usually, the maximum tetanus tension is from 1.2 to 1.8 times greater than the maximum tension during a twitch. Within the muscle, many elastic structures, connected in series with the contractile elements, are stretched during contraction.
SpletPostmortem muscle Once the life of an animal ends, the life-sustaining processes slowly cease, causing significant changes in the postmortem (after death) muscle. These changes represent the conversion of muscle to meat. pH changes Normally, after death, muscle becomes more acidic ( pH decreases). Splet16. okt. 2024 · Potassium is increased extracellularly during metabolic activity (muscle contraction) and has a direct effect on relaxing smooth muscles. Carbon dioxide is produced as a byproduct of the oxidative pathway and increases with metabolic activity. Carbon dioxide diffuses to vascular smooth muscle and triggers an intracellular pathway …
