BONES
give our body its
shape.
SKELETAL
SYSTEM
The human skeletal system consists of
all the bones, cartilage, tendons, and
ligaments in the body.
SKELETAL SYSTEM
Body support:
It gives our
body its shape.
SKELETAL SYSTEM
Facilitation of
movement: It
allows us to
move our
body.
SKELETAL SYSTEM
Protection of
internal
organs: It
protects vital
organs.
SKELETAL SYSTEM
Creation of
Blood Cells:
Inside the bone
marrow of
bones, blood
cells are
created.
Adult human
skeleton have
206 different
bones.
The skeletal system is
classified into two divisions
AXIAL SKELETON APPENDICULAR
SKELETON
AXIAL SKELETON
The axial skeleton are
the bones that make
up the central axis of
the body
SKULL
The skull is the
skeleton of the head.
It provides protection
for the brain.
SPINE
The spine, or
backbone, is a long
column of bones that
runs down the center
of a person’s back
It protects our spinal cord
RIBS AND STERNUM Sternum
Ribs
The ribs are long curved
bones that form the rib cage
The sternum or the breastbone is
the bone at the center of your
chest.
The rib cage protects the
heart and lungs.
APPENDICULAR
SKELETON
It consists of the
bones of the limbs,
and the bones that
attach the limbs to
the rest of the
body.
SCAPULA
The scapula, also
known as the
shoulder blade, is a
thin, flat, triangular
bone in your upper
back.
• Humerus – bone of our
upper arms.
• Radius and Ulna – bones of
our lower arms.
• Carpal and Metacarpals –
bones of our wrist and
palm.
• Phalanges – bones of our
fingers.
BONES OF THE ARMS
PELVIS
The pelvis supports
the lower
extremities and
aids in the
movement of our
legs.
BONES OF THE LEGS
• Femur – bone of our upper
legs.
• Tibia and Fibula – bones of
our lower leg.
• Tarsal and Metatarsal –
bones of our foot.
• Phalanges – bones of our
toes.
Tarsal
Metatarsals
Phalanges
Build the skeleton!
Your bones are for
life. Look after
them and they will
carry you far.

Editor's Notes

  • #4 Major roles or functions Ask them what do they think are the other role or function of the skeletal system. Cartilage: Soft, gel-like padding between bones that protects joints and facilitates movement. Ligaments: Elastic bands of tissue that connect bone to bone and provide stability to the joint. Tendons: Bands of tissue that connect muscle to bone.
  • #6 Bones together with our muscles facilitate the movement of our body
  • #7 Tell them that the bones acts as an armor inside our body.
  • #8 Mention bulalo as an example of the bone marrow
  • #9 Before moving onto the next slide, ask them what were the four major functions of the skeletal system Discuss about the bones fusing as we grow (make the babies skull as an example) Adult human – 25 years old
  • #12 Ask them what major organ does the skull protects Tell them that the skull has 22 bones in total but generally these bones are called the skull.
  • #13 There are 33 vertebrae for babies 26 vertebrae for adults
  • #14 There are 12 pairs of ribs which forms the rib cage Ask them what major organ does the rib cage protects Before moving to appendicular, recall the bones of the axial skeleton
  • #15 Ask them what are our limbs
