The thyroid gland is hugely important because it is the only means by which your body absorbs iodine to produce a hormone which is necessary for nearly every metabolic function in the body (everything from body temperature regulation and brain development, to converting food into energy).
Sprainâcomplete or incomplete tear in supporting ligaments surrounding a joint caused by a twisting or wrenching motion. Strainâacute or chronic injury to a muscle or tendinous attachment caused by stress, overuse, or over stretching. Classified as mild, moderate, or severe (see Classifying sprains and strains)
Causes of Sprains and Strains. A sprain is caused by a ligament being stretched too far. Ligaments are very strong and can allow a joint to move, but they do not have much elasticity. That means that when the ligament is stretched too far, tears can occur.
