Are you aware that you actually possess six senses? The sixth is a muscular sense responsible for directing your muscles intelligently to the exact extent necessary for each action you perform. For example， when you reach for an object， the sensory nerves linking the muscles to the brain stop your hand at the correct spot. This automatic perception of the position of your muscles in relation to the object is your muscular sense in action. 

Muscles are stringly bundles of fibers varying from one five-thousandth of an inch to about three inches. They have three unique characteristics， they can become shorter and thicker; they can stretch; and they can retract to their original positions. Under a high-powered microscope， muscle tissue is seen as long， slender cells with a grainy texture like wood. 

More than half of a person‘s body is composed of muscle fibers， most of which are involuntary—in other words， work without conscious direction. The voluntary muscles， those that we move consciously to perform. particular actions， number more than five hundred. Women have only 60 to 70 percent as much muscle as men for their body mass. That is why an average woman can’t lift as much， throw as far， or hit as hard as an average man. 

66. According to the selection， the muscular sense is responsible for ______.

“Fingers were made before forks” when a person gives up good manners， puts aside knife and fork， and dives into his food， someone is likely to repeat that saying. 

The fork was an ancient agricultural tool， but for centuries no one thought of eating with it. Not until the eleventh century， when a young lady from Constantinople brought her fork to Italy， did the custom reach Europe. 

By the fifteenth century the use of the fork was widespread in Italy. The English explanation was that Italians were averse to eating food touched with fingers， “Seeing all men‘s fingers are not alike clean.” English travellers kept their friends in stitches while describing this ridiculous Italian custom.
