Musculature variations

Variations in musculature are not as interesting from the standpoint of biochemistry as those involving other structures, but there are some available facts regarding variation in this area which are of considerable general interest. Because they emphasize the general importance of individuality, they support the specific theme of this bookthe importance of biochemical individuality. 

From the standpoint of general interest the variations in the musculature of human hands are worthy of attention, especially so since it is often supposed that the human hand is a standard piece of equipment which all normal people possess. The writer has seen a magnificently produced motion picture using a highly involved model, which showed just how every intricate movement of "the hand" is made.

Since we are digressing somewhat from biochemical consideration it may be well to remind ourselves that the basic anatomy, including the musculature, is not the same in men and women for this reason a woman cannot throw a ball as a man can, nor can women run in competition with men. However, as swimmers women show up very well, in contrast to their lack of ability to throw well or run fast Within the sexes, however, there are variations in anatomy so that...
