work to do.

5. In learning about the body, we have to study anatomy, physiology, and
hygiene.

6. The study of the various parts of the body, how they are formed and
joined together, is anatomy. Physiology tells us what the body does,
hygiene tells us how to take care of it.

CHAPTER II

A GENERAL VIEW OF THE BODY.

~1. Parts of the Body.~--What do we call the main part of a tree? The
trunk, you say. The main part of the body is also called its _trunk_.
There are two arms and two legs growing out of the human trunk. The
branches of a tree we call limbs, and so we speak of the arms and legs
as _limbs_. We sometimes call the arms the _upper extremities_, and the
legs the _lower extremities_. At the top of the trunk is the head.

~2. Names of the Parts.~--Now let us look more closely at these
different parts. As we speak the name of each part, let each one touch
that part of himself which is named. We will begin with the head. The
chief parts of the head are the _skull_ and the _face_. The _forehead_,
the _temples_, the _cheeks_, the _eyes_, the _ears_, the _nose_, the
_mouth_, and the _chin_ are parts of the face.

~3.~ The chief parts of the trunk are the _chest_, the _abdomen_
(ab-do'-men), and the _backbone_. The head is joined to the trunk by the
_neck_.

~4.~ Each arm has a _shoulder_, _upper-arm_, _fore-arm_, _wrist_, and
_hand_. The _fingers_ are a part of the hand.

~5.~ Each leg has a _hip_, _thigh_, _lower leg_, _ankle_, and _foot_.
The _toes_ are a part of the foot.

~6.~ Our hands and face and the whole body are covered with something as
soft and smooth as the finest silk. It is the _skin_. What is it that
grows from the skin on the head? and what at the ends of the fingers and
the toes? We shall learn more about the skin, the hair, and the nails in
another lesson.

~7.~ The body has two sides, the right side and the left side, which are
alike. We have two eyes, two ears, two arms, etc. We have but one nose,
one mouth, and one chin, but each of these organs has two halves, which
are just alike.

SUMMARY.

1. The body has a head and trunk, two arms, and two legs.

2. The parts of the head are the skull and face. The forehead, temples,
cheeks, eyes, ears, nose, mouth and chin are parts of the face.

3. The parts of the trunk are, the chest, abdomen, and backbone. The
neck joins the head and trunk.

4. Each arm has a shoulder, upper-arm, fore-arm, wrist, and hand. The
fingers bel
