The tongue is anchored to the mouth by webs of tough tissue and mucosa. The tether holding down the front of the tongue is called the frenum. In the back of the mouth, the tongue is anchored into the hyoid bone. The tongue is vital for chewing and swallowing food, as well as for speech. The four common tastes are sweet, sour, bitter, and salty. A fifth taste, called umami, results from tasting glutamate (present in MSG).
There are rules for games, for social clubs, for sports and for adults in the workplace. There are also rules imposed by morality and custom that play an important role in telling us what we should and should not do. However, some rules -- those made by the state or the courts -- are called laws. Laws resemble morality because they are designed to control or alter our behaviour.
We need to constantly reform our laws so we can make sure that our system of law and justice meets the challenges of our society. As people change the way they live and work, some laws may become obsolete. Or new situations may arise that no existing law deals with.aw reform. Every day, we hear about social issues, medical developments, and new types of technology. All of these raise moral and legal questions. These kinds of changes mean we need to constantly reform our laws so we can make sure that our system of law and justice meets the challenges of our society.
