THE WONDERFUL STRUCTURE AND
FUNCTIONS OFTHE HUMANB0DY
NO. II.


Having given synopsis of the framework
and Enclosure muscular system) of the hui
man body, in my last article will now pro.
coed to describe the various kinds of machin-
cry that are in constant operation within the
walls of this grand and noble structure, our
body by which the great variety of motions
and functions are performed. What an intri.
cate set of machinery, and yet how perfect
Everything Tor its special purpose. We might
say, the human body is indeed, d pIurS6us
unum, et maItam IN paroo, -one composed
of many, and much in little.
The blood from which material the tissues
of all parts of the body are constructed, il
manufactured by the machinery called diges-
ton and ABSORPTION. Them in order that the
blood may be used to construct all parts of
the body, or supply its wastes, it must be con-
veyed to all parts. There is wonderful set
of machinery for performing this work, called
circulation Then again, there is an apparat-
US for changing the blood, (after having made
its rolnd throughout the whole system, alb.
sorbing all impurities that 1t may meet,) into
proper state for snoiher routine, called re-
spiration. Then, the most wonderful of all
is, the complete net work Of telegraph lines,
forming lines of communication to the most
remote parts Of the structure, as well as to
its machinery, SO that each harmonize one
with the other This is called the nervous
system. The brain is the great central office
of this system, from which messages are sent,
through the nerves, to all parts Of the body,
and to which messages are sent from all parts
of the body. The brain is the seat of the
mind.
Messages are sent by means of the nerves
to the muscles, whenever the mind wills that
any part of the body move. Thus when you
want to move hand, messages are sent from
the brain to the muscles that move it, When
the mind wills thatthe whole body shall move
great number of these messages are sent in
all directions at once. The mind, too, receives
messages through the nerves of the special
senses. When we see, something is sent by
means of the nerves of the eye to the brain,
and thus reaches the mind, just as electricity
goes along tbeswires of telegraph. And SO
it may be said of the other senses The brain
sends out messages by one set Of nerves, aud
receives messages by another. The nerves by
which it sends out messages are called motor
nerves, or nerves of motion. The nerves by
which it receives messages are called sympa.
thetic nerves, or nerves of sensation Thus
if your hand comes IN contact with burning
surface, you feel pain, and quickly draw it
away. The sensation produced in this case.

so that the MUD is conscious of pain and
then the brain sends message by the motor
nerves to muscles of the arm, and they draw
the hand away from the pain producing OBJ
ject. Thus, we know, that the nerves are the
means of this connection between the mind
and the various parts of the body in this way
If the nerves of any part are severed, the
part cannot move, and there is no feeling in
it you may pinch or cut it without produce
ing any pain, because the mind has lost It's
connection with it. And the muscles Of that
part will not act if the mind sends message
Their than where the nerves are divided, just
as whom telegraph wire is broken, the cleo
l,tficity will 60 only to the point whore it is
broken.
The nerves are white cords. The spinal
cord is the main line of the nervous system
from which nerves branch out to all parts OF
the human SYSTEM Tho brain is soft, some
thing like boiled corn-starch. 1t is the soft.
est organ in the body. 1t is composed of two
kinds of substances. Tho outside is of a
Fgrayish substance, supposed to be the active
part of The brain. The inside is a white sub
stance, corresponding with the nerves, sup
posed to be the sensitive part of the BRAIN
The brain Is very irregular, on the outer sur
face. tits covered by three different skins Oh
membranes, one Of which is very thick ant
strong, so as to protect this delicate organ
from injury. 1t is divided into upper large
brain; called tetebruni, and smaller brain iy
