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)
A sprain and a strain are both minor injuries, not fractured bones that impact the soft tissue of muscles, ligaments, and tendons. The difference between a strain and a sprain is that a strain is an injury to a muscle or tendon and a sprain has affected ligament tissue. Both occur at joints where ligaments connect bone to bone and tendons connect bone to muscles. They are usually temporary, mild injuries that get treated similarly and heal quickly.
