Dictionary » T » Twitch Twitchtwitch 1. The act of twitching; a pull with a jerk; a short, sudden, quick pull; as, a twitch by the sleeve. 2. A short, spastic contraction of the fibres or muscles; a simple muscular contraction; as, convulsive twitches; a twitch in the side. 3. (Science: veterinary) A stick with a hole in one end through which passes a loop, which can be drawn tightly over the upper lip or an ear of a horse. By twisting the stick the compression is made sufficiently painful to keep the animal quiet during a slight surgical operation. ![]()

Results from our forumRe: Muscle Contraction: StrengthA 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 ...

Cats vs. Humans... 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 ...

Cats vs. Humans... 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, ...
