PHYSIOLOGY AND HYGIENE.


! One Of the first duties of the teacher il
| to arouse sn interest in q study. Interest
IL the only connecting link between
teaching as an act and education as result
of that act. IL the teacher finds that he
can not develop an interest in study. he
may rest assured that there is something
wrong with himself, with tho pupils OF
with the subject child has q natural
mental appetite, as he has a natural phv-
steal appetite. Either one may be de-
stroyed by improper food. II is impor.
tant that the teacher should prepare with
care the childs mental food. Hav ng
done this, lack OF interest will seldom
occur. In the following suggestions 1t is
understood that the teacher has the actual
objects before the class where the facts
may be understood by observation.
III. Muscle.
1. Let the pupils first make numer
Gus comparisons between flesh and bone.
2. Most of the fieshy part Of the body
is muscle.
3. Every muscle is made up of large
! number OF smaller muscles which seem to
be doEe up in bundles.
4. Muscle has the power Of drawing it,
self together, and Of stretching itself out.
5. When muscle draws itself together
it is said to contract; when it stretches
itself out is said to relax.
! o. Muscle is the only part OF the body
which has the power of contracting.
Z. The muscles are attached TO the
bones,
s. Some muscles are attached directly
TO the bones; others are attached by
white cords These cords are smooth
and very strong.
0. When the muscle contracts, it
moves one OF the bones to which 1t is at
tached.
10. la cord is cut the muscle can not
move the bone.
IL. Most muscles arc longer than they
are wide. and have broad part near the
middle.
~. When muscle contracts the ends
are drawn together and the middle part
becomes larger This can be shown by
calling attention to the biceps.l
10. Most muscles are arranged in
pairs, there being one on each side of the
tone. Where one contracts the other re-
lakes to allow the bone to move; then the
one which relaxed contracts and the one
which contracted first relaxes and the
bone is moved back again.
Ii. Muscle makes every movement In
the body, except the downward which
may be made by the weight OF the part
moved.
Is. Most muscles are between the
joints II they were near the joints. the
joints could not move easily.
16. Those muscles which have the
most work to do are larger. harder and
stronger than the others.
II. After muscle has been used very
much IL will not contract-then We say
that We are tired.
| 1S. We should take exercise to
strengthen oar muscles, Farmers and
blacksmiths have strong, hard muscles be-
cause they use them in doing hard work.
10. We should take such exercise as
will strengthen all Of the muscles.
20. Walking strengthens the muscles
OF the legs.
81. Throwing, pulling and swimming
strengthens the muscles Of the arms.
%. Twisting and bending strengthens
the muscles Of the side and back.
~. Rolling the head strengthens tho
muscles OF the neck.
"a. Rolling the shoulders strengthens
the MUSCLES OF the shoulders.
25. Some people become deformed by
failing to keep all OF these muscles
strengthened.
26. All the uses Of the muscles.
(a) they produce movement il the
body
tb) They protect the bones from in
jury.
(e) They protect other inside parts of
the body.
(d) They give shape to the body.
(e) They give beauty to the body.
