Suppose that you made a

wooden puppet. What should you

do to move its arms? The arms of

the puppet will surely not move

unless you place a joint where the

arms are connected to the shoul-
der. How will you make its legs

movable then? You have to use an

articulating piece again where its

legs join the trunk. Only then can

you move the wooden puppet's

arms and legs. Likewise, if you

separate the wood you have used for arms and legs into

two pieces and place articulating pieces, or joints, be-

tween these pieces, then the puppet's arms and legs will
also be bendable at the elbows and knees respectively. As

may be clearly understood by

this example, having many

bones and joints placed be-

tween them where necessary

enables us to move easily.
