Where does anatomy end and kinesiology begin? In truth, there
is no answer because the question itself is not valid. One might
as well ask, “Where does the study of words end and the
writing of compositions (or articles, or books) begin?” or “Where
does the study of building materials end and the designing and erecting
of buildings begin?” Just as words are the elements used
in all writing, whether creative, factual, or expository, and just
as bricks, wood, cement, metal, and glass are some of the elements
used in building, so bones, joints, muscles, connective tissue, blood
vessels, and nerves are the vital elements of human motion. They
are the essential elements used in batting a baseball, passing and
carrying a football, shooting a basketball into the basket—in
fact, in all running, walking, jumping, throwing, striking, catching,
and swimming; likewise, one finds them in keyboarding, manual labor,
painting, sewing, knitting, and so forth, almost without end.
