The term muscle means a "contractible animal tissue consisting of bundles of fibers," late 14c., "a muscle of the body," from Latin musculus "a muscle," literally "a little mouse," diminutive of mus "mouse."

There are over six hundred muscles in the human body. Does muscle memory exist? Is the brain a muscle requiring exercise? All of our muscles require exercise to get stronger. Creativity and innovation require exercise to grow. Exercise your brain daily to enjoy the fun of creating something new.
