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)
Sprains and strains, while sometimes used interchangeably, are not the same thing. A sprain is an injury to a ligament, the tough, fibrous tissue that connects bones to other bone. Ligament injuries involve a stretching or a tearing of this tissue. A strain, on the other hand, is an injury to either a muscle or a tendon, the tissue that connects muscles to bones.
