Skeletal System
5th Grade
TEKS
Identify fourteen bones and describe the
structure and function of the muscular
and skeletal system as they relate to
physical performance such as muscles
pull on bones to cause movement,
muscles work in pairs, and muscles work
by contracting and relaxing. (5.4E)
5th Grade
• What is the purpose of the skeletal system?
• What would happen if you did not have a skeletal
system?
Joint – where two bones
meet
Bones – bones are hard and
support the body
Tendon – connects muscle
to bone

Start!!!
What is the skeletal
system?
The skeletal system is all of
the bones of our body that
give us our shape.
Why is the skeletal system important?
• Our bones are
important because they
give our body structure
and they protect
important organs like
our heart, lungs, and
brain.
What would our bodies be like if we did not have a
skeletal system?
How are bones and muscles different?
• Bones are stiff and strong and cannot bend.
• Muscles are connected to bones and help
them move.
Muscles
Bones
Tendons
• Muscles are connected to bones by tendons.
Muscle
Your Head and Skull
SKULL
• The skull is the bone that protects our brain
and gives our head its shape.
The Torso
Clavicle
• The ribs are a set of
bones that protect our
heart and lungs.
• Your ribs get extra
support from the
sternum.
• Your collar bone is
called your clavicle.
Ribs
Sternum
The Spine and Vertebrae
• Vertebrae are the small
bones that make up our
spine, or back bone.
Pelvis
• The pelvis is a large bony
structure that connects our
upper body with our lower
body.
Upper body
Pelvis
Lower body
If bones can’t bend, then why
does our body bend?
• Our body can bend in places
like our elbows, fingers, and
knees because those are
called joints.
• A joint is the place where
two bones meet and
muscles hold them together
and help them bend.
A special bone
• To keep your knee joint
safe, it is covered by the
patella, or knee cap.
• Your patella protects
the muscles that help
your knee bend.
Big bones!!!
Femur
• Your femur is the biggest
bone in your body. It is
the top part of your leg.
Humerus
• Your humerus is the top
part of your arm. It
connects your shoulder
to your elbow.
Tibia and Fibula
Fractures
The tibia and fibula are
bones in our lower leg.
Ulna and Radius
Radius is on the same
side as our thumb.
Ulna is on the same
side as our pinky.
Phalanges
• Phalanges are the very small bones that make
up our fingers.

What problems could occur with
the skeletal system?
Scoliosis – spine curves
too much
Fractures – occur when a
bone snaps, shatters, or
cracks
Osteoporosis – bones
become thin, spongy, and brittle
Bones growing too fast

Growing pains
Arthritis - the inflammation of a joint, and people who have it experience
swelling, warmth, pain, and often have trouble moving
