the action always gets shorter to do it Muscles always contract to get movement to happen Tendons attach muscle to bone To hit something requires the use of your whole body You move because your muscles move your bones There are more than 600 muscles in your body Muscle makes up about 85%of your body weight You need 17 muscles to smile and 43 muscles to frown

Bones Cartilage is very strong and flexible We have cartilage in our nose and ears Our skeleton is needed for support and protection 3 bones that protect soft things are the ribcage, the skull, and hips 3 bones that support you when you stand up are the spine, the feet,

and the bones that make up the leg (femur, tibia, fibula) Your teeth are the strongest bones in your body There are 3 bones in each ear. These are the tiniest bones in your

body. When you crack your knuckles you are pulling apart the bones in your

fingers and are letting air into your joint knuckle When you are born you have 350 bones and as you age some of these

fuse together to give an adult 200 bones Your spine is made up of 33 small bones stacked on top of each other

(separated by a soft, squishy piece of cartilage) The longest bone ever found was a 7ft long arm bone of a brachiosaur Birds have hollow bones, we do not have any hollow bones The longest bone is the body is the femur

Starting a New HumanEvery human cell has 46 chromosomes- ½ from Mom, and ½ from Dad. Therefore the egg has 23 and the sperm has 23. 1 egg or 1 sperm is called a gamete and together they are called a zygote. 1 egg + 1 sperm= the 1st cell (the first cell divides from 1 cell to 100,000’s of cells in 48hrs, which is the fastest cell division of ‘your life’) (which will divide instantly). A zygote turns into an embryo, which has no distinct characteristics. As soon as you can tell what it’s distinct characteristics are it is called a fetus.
