There are seven neck vertebrae, twelve upper and mid-back vertebrae, and five low back vertebrae. It is important to lubricate the joints via exercise and activity and by drinking plenty of water. To determine how much water you need, divide your weight by 2. For example, if you weigh 150 pounds, divide by 2, that equals 75 ounces, which is almost 9 glasses of water. Muscles attach to bones and cross over joints.
Muscles move the joints.
Whenever you injure, strain or weaken a muscle, a joint is usually affected. Whenever a joint is injured, strained or weakened, muscles are affected. A weakness in a joint or muscle sets up a chain reaction so that other joints and muscles, as well as other parts of the body, compensate. Weaknesses in any part of the body need to be corrected in order for the body to function at its best. Certain muscles are related to certain meridians and organs of the body.
