Today we are going to learn about one of the organ systems—the skeletal system. This system is all about the bones in our bodies. Bones have five different functions, or purposes. At first glance, the skeletal system might not seem as important as some of the other systems, but today you’ll learn why we can’t live without it.

Notes Remember to be filling in your notes sheet as we go through the information together. After we write our notes, we will review using the PowerPoint.

What are the five functions of the skeletal system?

Functions of Bones Provide shape and support to the body Protect internal organs Enable motion Make blood cells Store minerals

Function #1: Shape & Support Provide shape and support to the body

Bones determine an animal’s shape

Shape is determined by bones

Not just shape, but support

Function #2: Protect Internal Organs

Function #3: Help us to move Enable motion by giving muscles a place to attach themselves http://www.youtube.com/watch?v=B4EBMZoX1b4

Function #4: Make Blood Cells

Function #5: Store Minerals Got Milk? Your body stores calcium and other minerals in your bones, so you can save them for later. Eating/drinking calcium makes bones stronger, because more minerals are stored inside them.

Bone Facts Bone is five times stronger than mild steel. Every three months our bone cells are completely replaced. Almost a quarter of your bones are in your feet and ankles. One out of 20 people have an extra rib. A person's nose and ears continue to grow throughout his or her life. Your thumb is the same size as your nose.

Exit Slip Clear everything off of your table. Close lab books and put them on the floor. NO TALKING, at all. If you have a question raise your hand SILENTLY and wait for the teacher. When you’re done, flip your exit slip over and draw a picture of a skull.

Question 1 1. True or False: We would not be able to move without the skeletal system.

Question 2 2. True or False: Blood cells are made inside of bones, so without the skeletal system we would not have blood.

Question 3 3. Which is not a function of the skeletal system: Protection Movement Storage Strength Support

Question 4 4. Write at least one sentence explaining why we need to skeletal system to stay alive.

Thursday Feb 7 or Friday Feb 8 Do Now: Explain how the skeletal system helps with movement. What do you know about the muscular system? True or False: Your heart is a muscle. Date Table of Contents Page 2-7-13 or 2-8-13 Muscular System Notes

Notes Remember to write all the information on your notes sheet as we go through it together.

Facts about the Muscular System

A single muscle cell of the sartorius muscle in the thigh can be more than 12 inches long. The strongest muscle of the body is the masseter muscle used for chewing!

Your hand contains 20 different muscles. If all your muscles could pull in one direction you could create a force of 25 tons! Muscles account for approximately 40% of your body weight.

No matter how much you exercise you can not increase the number of muscle cells you have. By getting bigger, via strength training, you are simply increasing the size of each muscle cell. The muscle that lets your eye blink is the fastest muscle in your body. It allows you to blink 5 times a second.

You have all the muscle fiber you will ever have at birth You have all the muscle fiber you will ever have at birth. Once damaged they can't be replaced. Arnold Schwarzenegger has as many muscle fibers as you - They're just thicker! Want to know more about steroids? Check out the extra credit opportunity later.

Banging your head against a wall uses 150 calories an hour. The record for most pushups ever performed in one day is 46,001. Weight lifters who work out in gyms decorated in blue can lift heavier weights. Kissing for one minute burns 26 calories. The amount of time in a day that a preschooler is sedentary: 89%.
