Why does the human hand tremble?
Factors that can make a normal tremor more noticeable include stress, anxiety, fatigue , withdrawal of alcohol or certain other drugs (such as opioids), an overactive thyroid gland (hyperthyroidism), consumption of caffeine , and use of certain drugs.. The reason for all trembling ultimately is due to way muscles work. At a microlevel there are [[sarcomeres]], which are the base unit of muscles, and are analagous to the thinnest threads of a muscle. These threads actually consist of to parts that overlap by a greater of lesser extent depending on whether the muscles are expanding or contracting. At any given time half the sarcomeres are at rest, and the other half take up the tension if the muscle is in use, and alternate taking up the strain. When the body is stressed (eg due to fatigue, stress, other factors), then this mechanism does not work perfectly and the result is that when the alternate groups of sacromeres do not perfectly take the strain the muscle will tremble. This is particularly noticeable at the extremities as it is easier for a small motion to be exagerrated..

What can you do for tendonitis?
You can do A LOT of things for Tendonitis. Some are more effective than others, of course. Tendonitis symptoms show up due to a variety of factors in the body. If you don't effectively deal with those factors, the problem will remain, and/or come back again sooner than later. Especially if you continue to do whatever activities that you've been doing that contributed to (but did not cause) the problem. Dealing with just one or two of the factors to some degree can lower pain levels, but won't fix the cause of the problem. The factors that cause tendonitis symptoms are muscle tightness, connective tissue tightness, inflammation, nutritional insufficiency/deficiency. Some usually prescribed/used methods that may decrease symptoms but don't fix or cure tendonitis are Rest, Anti-inflammatories, Pain Killers, wrists and splints, and corticosteroid injections.

"Hand of one is hand of all" is a theory, whereby all those who participate in a crime become guilty as the actual wrong doer. In other words act of one is considered act of all.

"One who joins with another to accomplish an illegal purpose is liable criminally for everything done by his confederate incidental to the execution of the common design and purpose."[State v. Curry, 370 S.C. 674, 684 (S.C. Ct. App. 2006)]. This was further expanded by the Supreme Court of South Carolina in State v. Kelsey, 331 S.C. 50, 76-77, 502 S.E.2d 63, 76 (1998),where it was held that "if a crime is committed by two or more persons who are acting together in the commission of a crime, then the act of one is the act of both." Supreme Court approved the following charge for accomplice liability in State v. Cannon, 49 S.C. 550, 27 S.E. 526: "The common purpose may not have been to kill and murder, but if it was unlawful, as, for instance, to break in and steal, and in the execution of this common purpose a homicide is committed by one, as a probable or natural consequence of the acts done in pursuance of the common design, then all present participating in the unlawful common design are as guilty as the slayer."
