Muscles are amazing.From the tiniest--the ciliary muscles in the eye--to the biggest--the quadriceps femoris--we owe much of our ability to interact with our environment to our muscles. They of course rely on the nervous and endocrine systems (physiology's yin and yang) but without them the former would just sort of lie there. Rather an unsettling image....
SOOO, take care of your muscles and they will never let you down. Ha!
