The Human Skeleton

Long Bones e.g. femur, humerus, tibia, fibula, the metatarsals, metacarpals and phalanges.

Flat bones e.g. Cranium, ribs

Irregular bones e.g. vertebrae, face and patelle

Short bones e.g. carpals, tarsal

• The skeleton gives us our shape and determins our size
• The skeleton supports our muscles and organs
• The skeleton protects delecate parts of the body e.g. brain, lungs
• It allows us to move. Muscles attach to the bones and work like leavers
• Blood cells are made in bone marrow

• Ball and socket joints e.g. shoulders, hips.
• Pivot joints e.g. atlas, axis
• Saddle joints - The thumb is the only saddle joint
• Hinge joints e.g knee, elbow
• Condyloid joints e.g between the metacarpals and phalanges in the hand
• Gliding joints e.g. between the tarsals in the ankle
