You have one ear on either side of your head. You use your ears to hear with. You have two ears shaped the way they are so that you can tell which direction sound is coming from.
Your elbow is the joint halfway up your arm, so you can bend your arm. If you hit the back of your elbow it feels funny, so people call it your funny bone. Your funny bone is actually just a nerve.
You have two eyes on your face, just above your nose. You use your eyes to see things. You close your eyes when you are asleep. The eye in the photo is brown.
You have two eyebrows, one above each eye. An eyebrow is a strip of hair between your forehead and your eye socket. Eyebrows help to stop sweat running from your forehead into your eyes.
Your eyelashes are hairs that grow on the edges of your eyelids. Eyelashes protect your eyes, by stopping dirt and dust from getting in your eyes.
