Muscular System
Introduction
Animals can’t speak, but can communicate with each other. Bees can fly making circles when they find some flowers. Whales sing in order to communicate. Monkeys can produce some meaningful noises to express their mood. But we, humans, can speak to communicate.
We are animals, too. Animals can’t speak, but humans can. We are vertebrate and we can move. We have two legs and two hands. We can walk, run, dance, swim... But we can’t fly, since we don’t have wings.
We’ve got lungs. We don’t have gills. So we can’t breathe under water.
Our body covering consists in skin with hair. We not only eat vegetables as herbivores do, but meat as well. We are omnivore.
Babies are born from mother’s womb. Mummy feeds her baby with milk. So we are mammals.

A human skeletal system has around 206 bones. These bones meet at joints. Joints allow us to move. The skeleton also contains cartilage for elasticity. Muscles are strong strips of fibrous tissue that hold bones together at joints.
The most little bone in the body is the stirrup. Bones meet at joints. The bones located in the spinal column are the vertebrae. There are three long bones in our leg : The femur, the tibia and the fibula.
In our trunk we can find the clavicle, the sternum and the rib cage.
