          The Skeleton System
Bones protect our vital
  organs.
Inside the bone is jelly-
  like bone marrow.
As you grow older some
  of your bones grow
  together.
The Muscular System
          There 630 active muscles
            in your body.
          Muscles are bundles of
            cells and fibers.
          Muscles tighten up, and
            then they relax.
          .
                   Muscles

• About 630 muscles
• Relax and contract to
  move bones
• Your muscles are over
  your body
• You have three
  different bones in your
  body
            Skeletal System
• 360 bones in body
  when born
• 206 bones in body
  when you are about 10
  or 20
• It gives us shape
• Protects our organs
  such as brain, heart,
  and lungs
                  Muscular System
• There are 630 muscles
  in the human body.
• There are involuntary
  muscles like the heart
  and the intestines.
• There are also
  voluntary muscles like
  your wrists, and your
  legs.

                      Skeletal System
• There are thin films of
  slippery fluid which is
  cartilage.
• There are three main
  jobs of the skeletal
  system. The jobs are
  protecting the organs,
  it gives us our shape,
  and it allows us to
  move.

Skeletal System
        • It protects our vital
          organs.
        • Gives us the shape of
          our body.
        • When you’re a baby
          your skeleton had
          around 350 bones.
            Muscular System
• Our heart beats
  between 60 to 80 beats
  every minute, without
  having a break.
• Muscles can get
  shorter and pull, but
  can’t push.
       MUSCULAR SYSTEM
• Half our weight is
  mostly muscles
• Muscles work in a
  very simple way. All
  they do is tighten up
• There are 630 active
  muscles in the body
Skeletal System
        • Your skull protects
          your brain
        • If you didn’t have any
          bones you’d be a big
          blob
        • Your backbone helps
          you stand up straight
          Muscular system
• Muscles are bundles
  of cells and fibers.
• We have 600 major
  muscles.
• We have 240
  muscles that have
  specific jobs
Skeletal system
      • Your bones
        manufacture blood
        cells.
      • Our bones are held
        by our muscles
      • The smallest bones
        are in our ears
       MUSCULAR SYSTEM
• You have more than
  630 active muscles in
  your body.
• You also have 3 dozen
  in your jaw.
• You have 3 kinds of
  muscles in your body.
  [smooth, skeletal, and
  heart.]
SKELETAL SYSTEM
       • When you look at your
         skull with the Lateral
         View you can divide
         your skull into 25
         parts.
       • But when you look at
         your skull with the
         Interior View you can
         only divide it 17 parts.
            Muscular System
• Muscles are bundles of
  cells and fibers.
• There are 630 active
  muscles.
• Muscles only pull not
  push.
• Cardiac muscles are found
  in the heart .
• The muscular system
  compares well with a
  backhoe
SKELETAL SYSTEM
       •     You need joints which provide
             flexible connections between
             the bones

       •     Bones are made of a mix of
             hard stuff that gives them
             strength

       •     Hollowness makes bones
             strong and light

       •     Humans and giraffes have the
             same number of bones in their
             necks

                                Muscular System
        • Muscles are found on
          the walls of internal
          organs.
        • Deltoid Muscles are in
          both of your
          shoulders.
        • Muscles come in
          different shapes &
          sizes.

                               Skeletal System
                                          • The skull is fused
                                            bones.

                                            degrees like a shower
                                            head.

  about 640 muscles.
• The children have230
  muscles.
            Skeletal System

• It gives you shape.
• There is fluid in your
  body
• If you didn’t have any
  bones you wouldn’t
  have a shape.
           MUSCULAR SYSTEM
                                   MUSCULAR
                                      SYSTEM

         bones in your body .
       • When you are an
         adult you have

• Hinge joint of the knee
• Pivot joint of the neck
• Fixed joint of the skull
• Ball-and-socket joint
• You know that parts of
  your skeleton can move.
• They can move because of
  the way bones are joined
  together
MUSCULAR SYSTEM
