Page 1 Living Things Page 2 Living Things Bones and skeletons: What is a skeleton? People and many animals have bones inside their bodies. These bones are joined together to form a skeleton. A skeleton is a strong frame that supports our body from the inside. We learn about animals, like dinosaurs, that lived long ago from their skeletons. Internal Support The skeleton provides support to the body's tissues and organs. Joined Structure Bones connect at joints to create a complete skeletal system. Historical Record Fossilized skeletons allow scientists to study and understand creatures that lived millions of years ago. Page 3 Living Things Bones and skeletons: What is a skeleton?

These bones are different sizes and shapes. You can feel your bones through your skin. Bones are hard and strong. How many bones in your body can you name? Total Bones The complete adult human skeleton contains 206 bones of various sizes and shapes Vertebrae The spine consists of 26 bones that protect the spinal cord Hand Bones Each hand contains 27 bones, allowing for precise movements Page 4 Living Things Bones and skeletons: What is a skeleton?

It protects our vital organs, gives our body its shape, allows us to move, and helps us grow. Skeletons protect The parts inside our bodies are called organs. The body organs do important jobs that keep us alive and healthy. Our skeletons protect the main organs of our bodies. Skeletons give shape The bones of our skeleton are strong. The skeleton forms a frame that supports or holds up the rest of the body and gives the body its shape. Our skeleton makes our body firm. Skeletons allow us to move Our skeleton helps us to walk, run and move in lots of different ways. We can move because there are muscles joined to bones of the skeleton. Skeletons help us grow We grow and get bigger because our skeleton grows. An adult's skeleton is much bigger than a child's skeleton. An adult's skeleton has stopped growing.

Skeletons and movement Muscles make us move Muscles make us move. Bones are strong and hard. They cannot bend, but your body can move in many ways. All animals with skeletons have muscles attached to the bones. Muscles allow us to sit, stand, walk, run, bend, and stretch. They also make it possible to smile, hold a pen, eat, and talk. Muscles are found under the skin and cover the skeleton. They give your body its shape. Without muscles, our skeletons would be unable to move. The combination of rigid bones and flexible muscles allows for precise and varied movements.Read More
