Re: Muscle Contraction: Strength

A muscle contraction (also known as a muscle twitch or simply twitch) occurs when a muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten or remain the ...

Re: Muscle Contraction: Strength

... means that small motor units are recruited first. Large motor units are recruited last. Large motor units are the ones having fastest and largest twitch contraction, thus producing greatest force.

Re: In Vitro Meat - meat of the future?

... could just attach your engineered "mini-meat" onto a some sort of a mechanical stretcher with electrical stimulus, give it an occasional twitch or two for exercise and watch your meat grow. Of course, you'd need to pump some hormones, growth factors and nutrients on it as well. If our ...

... very different going on. Cats are like toggle switches. Humans are like water freezing and unfreezing. And yeah,... I would guess that the fast twitch to slow twitch ratio is higher in cats than humans, ... but not only that but some sort of structural difference at the microscopic level of ...

... their tendons, cartilage etc. is different in structure to allow the spring action of a jump. I imagine cats have disproportionately more 'fast-twitch' muscle than 'slow twitch' muscles in their legs, though I'm out of my depth here as I havent touched much on physiology in a while. Behaviourally, ...
