Body and Mind are Connected in Many Ways.

Whenever a person chooses to move,her body messages are sent from the brain and spinal cord to the bones and muscles, telling them what to do .Thought processes guide voluntary muscles.So when a person wants her arms or legs to move, her brain can control this action.Besides voluntary actions, the brain also sends out signals to individual blood vessels and organs, telling them  to ensure the muscles have what they need to perform.The brain does this involuntarily, meaning it's not something a person needs to think about doing or has any control over.Finally, the brain causes the body to excrete certain hormones that play an important role in physical performance.For instance,the hormone testosterone plays a role in muscle maintenance during exercise.
