Been wanting to know this for so long.

[LankedOut]

You mean like slow twitch and fast twitch?

No like you're just sitting there and they start twitching. It happens with peoples eyes a lot. This muscle in my back has been twitching for like 5 minutes.

[Cityfan63]

After a workout it happens to me, just pumped I think.

[n9ne1]

Dont know always thought it was my veins had one it my lip earlier so dont think it was a muscle twitch but get them under my eye and in my arms all the time

I think it's when the cell dies, I don't think that it is a bad thing though, they just grow back or whatever. (probably bro science lol)

[clementine44]

Im sorry man, but I think it means you got da aids.

muscle cells dont grow back normally



btw, thousands of cells die every minute (probably more)

Causes

* Diet deficiency
* Drug overdose (caffeine)
* Drug side effect (such as from diuretics, corticosteroids, or estrogens)
* Exercise
* Twitches not caused by disease or disorders (benign twitches)
o Often affecting the eyelids, calf, or thumb
o Normal and quite common, often triggered by stress or anxiety
o Come and go, and do not last for more than a few days

Nervous system conditions that can cause muscle twitching:

* Amyotrophic lateral sclerosis (ALS - Lou Gehrig's disease)
* Damage to the nerve that leads to a muscle
* Muscular dystrophy
* Spinal muscular atrophy
* Weak muscles (myopathy)

Symptoms that suggest a nervous system disorder include:

* Loss of, or change in sensation
* Loss of muscle size (wasting)
* Weakness

[slowbus]

it's the synapses firing off electrical signals to your muscle fibers, they twitch in response(they are basically contracting), it's your cns saying o hai dere

I didn't say muscle cells, and I meant they get replaced haha I'm still wrong though I think

[woodenpints]

For some reasons this happens sometime in my right tricep... I was sitting in class the other day and it happened and I probably looked like a douche because I couldn't stop my tricep from moving.

lol DEFINITELY broscience
AP Biology teacher (phD, teaching for like almost 30 years) says we (growing humans) basically have entirely new cells with the original ones dead after only 11 years, so all the cells you had at first in your body died. that's a sh*tload of cells, like easily in the billions, so you'd be twitching nonstop
