Prehistoric People
Prehistoric people are people who were alive before writing was invented.The picture to the right shows a tribe of prehistoric people.Prehistoric people looked a lot different then people today because they were not fully evolved.They looked more like an ape in the present.They looked and lived a lot different then humans today.They didn't go to the grocery store to get food like you and me.They had to hunt wanted to have a nice and tasty lunch.They didn't survive as long as you and me will,because they were lunch for a lot more animals then you and me are because they had to survive through those tough times.They also didn't have clothes for a long time.They lived in a grasslandish area.(shone above.)Prehistoric people lived about 2 million years ago,how ever writing was invented about 5,500 years ago.I have done ligaments and tendons below
Ligaments and Tendons
Bones are held together by a tough,stretchy tissue called ligaments.Ligaments also hold together cartilage and support muscles.Tendons are the white stretchy bands that connects bones to muscles.Joints are the things that connect your bones to other bones and allow them to move because if you didn't have joints you couldn't control your body.Ligaments hold together bones and support muscles.Tendons connect bones to muscles.Joints connect bones to other bones and allow them to move.That is all you need to know about ligaments,tendons,muscles, and joints.

The Muscular System
The Muscular system is the muscles of the body.There are three mane types of muscles:
smooth muscles,skeletal muscles and heart muscles.Skeletal muscles are muscles that help move bones and joints.Heart muscles are the heart and the many muscles surrounding it.The heart is the strongest muscle in the body.Smooth muscles line the insides of some organs.Such as the stomach,intestines,blood vessels and the bladder.There are voluntary muscles and involuntary muscles.Voluntary muscles move when you want them to.The triceps and biceps are voluntary muscles.Involuntary muscles are muscles that move even when your not telling them to.The heart is an involuntary muscle because it keeps on beating even when you're not thinking about it.
