  1. The Skeletal and Muscular Systems By Mrs. Hyde’s Class

  2. The Skeleton System Bones protect our vital organs. Inside the bone is jelly-like bone marrow. As you grow older some of your bones grow together.

  3. The Muscular System There 630 active muscles in your body. Muscles are bundles of cells and fibers. Muscles tighten up, and then they relax. .

  4. Muscles • About 630 muscles • Relax and contract to move bones • Your muscles are over your body • You have three different bones in your body

  5. Skeletal System • 360 bones in body when born • 206 bones in body when you are about 10 or 20 • It gives us shape • Protects our organs such as brain, heart, and lungs

  6. Muscular System • There are 630 muscles in the human body. • There are involuntary muscles like the heart and the intestines. • There are also voluntary muscles like your wrists, and your legs. http://dante.med.utoronto.ca/skeletalmuscle/publicationpictures4.htm

  7. Skeletal System • There are thin films of slippery fluid which is cartilage. • There are three main jobs of the skeletal system. The jobs are protecting the organs, it gives us our shape, and it allows us to move. http://www.bio.psu.edu/faculty/strauss/anatomy/skel/atlas.htm

  8. Skeletal System • It protects our vital organs. • Gives us the shape of our body. • When you’re a baby your skeleton had around 350 bones.

  9. Muscular System • Our heart beats between 60 to 80 beats every minute, without having a break. • Muscles can get shorter and pull, but can’t push.

  10. MUSCULAR SYSTEM • Half our weight is mostly muscles • Muscles work in a very simple way. All they do is tighten up • There are 630 active muscles in the body

  11. Skeletal System • Your skull protects your brain • If you didn’t have any bones you’d be a big blob • Your backbone helps you stand up straight

  12. Muscular system • Muscles are bundles of cells and fibers. • We have 600 major muscles. • We have 240 muscles that have specific jobs

  13. Skeletal system • Your bones manufacture blood cells. • Our bones are held by our muscles • The smallest bones are in our ears

  14. MUSCULAR SYSTEM • You have more than 630 active muscles in your body. • You also have 3 dozen in your jaw. • You have 3 kinds of muscles in your body. [smooth, skeletal, and heart.]

  15. SKELETAL SYSTEM • When you look at your skull with the Lateral View you can divide your skull into 25 parts. • But when you look at your skull with the Interior View you can only divide it 17 parts.

  16. Muscular System • Muscles are bundles of cells and fibers. • There are 630 active muscles. • Muscles only pull not push. • Cardiac muscles are found in the heart . • The muscular system compares well with a backhoe

  17. SKELETAL SYSTEM • You need joints which provide flexible connections between the bones • Bones are made of a mix of hard stuff that gives them strength • Hollowness makes bones strong and light • Humans and giraffes have the same number of bones in their necks http://emuseum.mnsu.edu/biology/humananatomy/skeletal/skull.html

  18. Muscular System • Muscles are found on the walls of internal organs. • Deltoid Muscles are in both of your shoulders. • Muscles come in different shapes & sizes. http://www.bcbsfl.com/ocyh_bodyatlas/muscles_bones.cfm

  19. http://infozone.imcpl.org/kids_skel.htm Skeletal System • The skull is fused bones. • The shoulder allows you to move 360 degrees like a shower head. • Your blood brings food to your bones.

  20. Muscular System • The human body has about 640 muscles. • The children have230 muscles.

  21. Skeletal System • It gives you shape. • There is fluid in your body • If you didn’t have any bones you wouldn’t have a shape.

  22. MUSCULAR SYSTEM MUSCULAR SYSTEM • 1. You have about 460 muscles in your body • 2. Your heart beats constantly. • http://www.bartleby.com/107/

  23. SKELETAL SYSTEM • When you are born you have around 350 bones in your body . • When you are an adult you have around 206 bones.

  24. Skeletal System • Hinge joint of the knee • Pivot joint of the neck • Fixed joint of the skull • Ball-and-socket joint • You know that parts of your skeleton can move. • They can move because of the way bones are joined together

  25. MUSCULAR SYSTEM • There are 630 in the body.Muscles help your body work. • There are three kinds of muscles the smooth, heart, and skeletal

  26. Be sure to take great care of your muscular and skeletal systems!
