You all know when you're about to fall asleep, in let's say, your chair, like I do @ work everyday from 2-2:20, and you twitch or make a very spastic movement and almost punch your neighbor square in the nose or worse, punch yourself in the pecker?
This is called the Mycolonic twitches:
Myoclonus ( //) is brief, involuntary twitching of a muscle or a group of muscles. It describes a medical sign and, generally, is not a diagnosis of a disease. The myoclonic twitches are usually caused by sudden muscle contractions; they also can result from brief lapses of contraction. Contractions are called positive myoclonus; relaxations are called negative myoclonus. The most common time for people to encounter them is while falling asleep (hypnic jerk), but myoclonic jerks are also a sign of a number of neurological disorders.Hiccups are also a kind of myoclonic jerk specifically affecting the diaphragm. Also when a spasm is caused by another person it is known as a "provoked spasm". Shuddering attacks with babies also fall in this category.
Pretty intriguing stuff isn't it? Personally, I twitch aggressively when I'm heading into the dream world. Fainting goats and twitching humans reside in the same category of disorder, although twitching isn't quite as serious. Here's the picture. You're a Billy goat, you're on the run, and you are the direct pray of a famished Liger. A liger is a mixture of a Lion and Tiger. Supplementary research required if you wanna find out how G'd up this animal is. Back to the canvas. You're adrenaline is pumpong, but you need to calm this adrenaline ASAP. Tough luck, you're a fainting goat, you're genetics get the best of you and you experience temporary rigor mortis. You wake up murdered. Game over. Fainting goats were not initially the novelty they are today. They were breed because their muscles don't atrophy, therefore their muscles don't atrophy so they are leaner for slaughter. PETA is not to happy about these goats, and the term un-natural selection is associated with their "gift". On a side note, how cute is this BONUS video:
