Transcript of Bones and Muscles

WHAT DO
MUSCLES
DO?
Every part of

our body has muscles
The muscles that are part of the locomotor system. The locomotor system is what let us move the different parts of our body. It includes
bones, joints
and
muscles
.
THE MUSCLES
Muscles are attached to
bones by tendoms.
Most of the muscles of the head are in the face.
Some open and close the mouth and the eyes; others are for chewing and speaking. The
masseter
helps us chew our food.

The
neck
muscles (1) are in the neck.
The
pectorals
(2) are in the chest.
The
intercostals
(3) are between the ribs.
The
abdominals
(4) are under the ribcage and under the stomach.
THERE ARE MANY MUSCLES IN THE TRUNK
The deltoid (5) is in the shoulder.
The triceps (6) and the biceps (7) are in the upper arm.
The
trapezius
muscle is in our back. It helps us move our arms.

The
quadriceps
(8) are in the upper leg.
The
biceps femoris
is in the back of the upper leg.
The
gluteal muscles
are in the bottom.
We also have the
calf
muscles. These help us walk,run and jump.
Muscles are
flexible
and
elastic.
They are
soft
when relaxed.
They work in
pairs
:
They move our bones by
contracting
and
relaxing
.
When muscles contract, they get
shorter
, and when they relax, they get
longer
.
This is how we move the different parts of our bodies.
Tendoms
attach muscles to the bones.
Ligaments
attach bones to bones.

MUSCLES AND BONES ARE ATTACHED BY JOINTS
We have two types of muscles:
voluntary
and
involuntary
. We can move voluntary muscles when we want but we can't control involuntary muscles. Our
heart
is an involuntary muscle. It moves automatically. There are also involuntary muscles in our
stomach
that help us to digest our food.
SKULL
The
skull
is the head. It protects the brain and gives shape to the face

TRUNK
The trunk has two parts: The Thorax and the Abdomen.
The
ribcage
is in the trunk. It protects the
heart
and the
lungs
. It is made up of:
At the back: the
backbone
. This is made of small bones called
vertebrae
.
At the front: the
sternum
.
The
ribs
join the backbone and the sternum.

SCAPULA
PELVIS
In the
pelvis
we find the
HIPS
FEMUR
It is the longest bone in your body
TIBIA
FIBULA
KNEE
ANKLE
THE LEG
THE SKELLETON
The
Skeleton
is made up of all the
bones
in our body.
An adult has
206
bones.
Bones are
hard and rigid.
They are made of
calcium
. Calcium can be found in food like
milk, salmon, broccoli, yoghourt and cheese
, so we need a lot of calcium to have strong bones and to grow up.

The skeleton has
three parts
: The
SKULL
, the
TRUNK
and the
LIMBS
.
The skeleton has two functions: It
supports
our body and it
protects
the delicate organs inside it.
BONES
TYPES OF BONES
The bones in our body are all
different shapes.
There are
three
types of bones:
Long
,
Short
and
Flat
.
Vertebrae are short bones
The tibia is a long bone
The bones in the skull are flat.
