• The smallest is the stirrup bone in the ear which can measure 1/10 of an inch.
Your face has 14 bones.
One fourth of your bones are located in your feet.
True or False: Children often bend their bones rather than break them.
TRUE! Their bones are more pliable, and tend to bend more without breaking.
1. Ligaments•Connective tissue that connects bone to bone
•Connective tissue that connects muscle to bone
2. Tendons
3. Cartilage
•Flexible connective tissue
•Found:–at ends of bones for cushioning and protection
–in bw vertebrae
•Give shape to certain body parts(ears, nose)
Months before birth, the skeleton is made of cartilage. Gradually the cartilage breaks down and is replaced by bone. Cartilage is replaced slowly by bone as solid tissue grows outward. Over time, the
bone reshapes to include blood vessels, nerves, and marrow. Bone-forming cells deposit the minerals calcium and phosphorous in bones,
making the bone tissue hard.

•Skeleton of newborn made mostly of cartilage
4. Bones
Cranium = Skull
Clavicle = collar boneRib cage (protect)
Sternum = breast bone
Vertebrae = backbones
Scoliosis
Humerus = upper arm boneUlna & radius = lower arm
Pelvis = hips
Femur = thigh bone (longest & strongest)
Patella = knee cap
Carpals = wrist bonesMetacarpals = hand bones
Phalanges = fingers & toes

Did You Know?
Humans and giraffes have the same number of bones in their necks? A Giraffe’s
neck vertebrae are just much, much longer!
The only bone not broken so far during any ski accident is one located
in your inner ear.
If you break your wrist as an adult it will take you 8 weeks to
heal. A five year old child who
breaks their wrist only takes 3 weeks to heal.
