The Skeletal System

By: Zoë Edwards & Laura May

Functions

Supports body Protects body Stores Calcium & Other Minerals Make blood cells (Produced by marrow) Protects organs

Keeping a Healthy System

Regular physical activity Nutritious eating plan Posture Lift objects carefully Treat injuries quickly Have calcium & other minerals in your diet

How the System Works w/ Other Systems

Tendons – Join muscle to muscle or muscle to bone

Connecting tissues link bones to muscles so that they can work together to move parts of the body

Skull protects brain (Nervous System) Skeleton system supports skin (Organ) Red & White blood cells are part of the

circulatory system

Joints

Hinge– The elbow is an example of this. It is similar to a door hinge.

Ball-and-socket– The hip is an example of this. The bone is capable of rotating on an axis.

Pivot– The neck is an example of this. It moves by rotating.

Gliding– The wrist is an example of this. It allows a bone to slide over another.

Common Bones Fibula Tibia Patella Femur Pelvis Lumoar Vertibre (Lower

back)

Cranium Clavicle Scapula Sternum Theoratic Vertibre (Upper

Back)

Fun Facts

206 bones in your body Hand has 27 bones Face has 14 bones Stirrup bone (ear) is the smallest bone Humans & Giraffes have the same # of bones

in their neck When you were born you had over 300 bones

Definitions

Joints – Places where 2 or more bones meet Cartilage – Allows 2 joints to move easily,

cushions bones, & supports soft tissues (nose & ear)

Ligaments – Hold bones in place @ the joints System – The framework of bones & other

tissues that support the body
