1. The Skeletal and Muscular Systems Get a moving and a grooving! :D Mr. Sanders

2. Spooky Skeletons The skeletal system is built out of bones and tissues. They form the skeleton. The skeleton is the inner framework of your body Skull Clavicle Sternum Ribs Humerus Vertebral column Ulna Radius Femur Patella Tibia Fibula Tarsals Metatarsals Phalanges Pelvis Carpals Metacarpals Phalanges

3. Spooky, Scary Skeletons Five functions of the skeleton Structure and Support Movement Protection Produce blood cells (Say whaaa???) Store minerals Skull Clavicle Sternum Ribs Humerus Vertebral column Ulna Radius Femur Patella Tibia Fibula Tarsals Metatarsals Phalanges Pelvis Carpals Metacarpals Phalanges

4. Spooky, Scary Skeletons Structure and Support The skeleton is important in giving you shape. Without it, you’d be a big, massive blob on the floor!

5. Spooky, Scary Skeletons Structure and Support The spinal column is the center of the skeleton. It is made up of 26 vertebrae. Vertebrae are flat, disc-shaped bones found in the back.

6. Spooky, Scary Skeletons Movement Muscles are attached to bones. They pull on bones and create movement. Bones are tied to each other by ligaments.

7. Spooky, Scary Skeletons Protection Bones also provide protection, the skull for example. Skull Clavicle Sternum Ribs Humerus Vertebral column Ulna Radius Femur Patella Tibia Fibula Tarsals Metatarsals Phalanges Pelvis Carpals Metacarpals Phalanges

8. Spooky, Scary Skeletons Storage Bones act like warehouses for minerals like calcium. When needed, the bones can release it into the blood.

9. Spooky, Scary Skeletons Produce blood cells Some act like factories in creating blood cells. The tissue that creates the cells is called the bone marrow. This is found primarily in long bones.

10. The Joints Joints are where two bones meet. There are immovable joints and movable joints. Most joints are movable. Skull Clavicle Sternum Ribs Humerus Vertebral column Ulna Radius Femur Patella Tibia Fibula Tarsals Metatarsals Phalanges Pelvis Carpals Metacarpals Phalanges

11. The Joints

12. Those Dry Bones The Outer Membrane is the outside. Compact bone is hard, dense and has canals for blood vessels. Spongy bone is lightweight. The Red Bone Marrow can fill the space. It produces blood cells. Yellow Bone Marrow stores fat.

13. Those Dry Bones Three characteristics of bones Strength Lightweight, but strong Can take more force than concrete or granite rock before breaking! Growth Bone is alive and grows. Even after growing taller, bone tissue continues to renew itself. Development When born, most bone is made out of cartilage. It turns into bone as your grow.

14. Those Dry Bones Osteoporosis Osteoporosis is a disease that occurs in later life. It is caused by mineral loss from the bones. The bones become porous and brittle (break easily).

15. Put Some Muscle Into It! There are two types of muscles in the body: voluntary and involuntary. Voluntary muscles are controlled by you. Involuntary are not controlled and act on their own

16. Soo Many Muscles Three different types of muscle tissue: Skeletal muscles Striated. Voluntary. Allow for movement of the body. Smooth muscles Not striated. Involuntary. Found in organs and blood vessels. Cardiac muscle Striated. Involuntary. Found specifically in the heart.

17. Partner Up Skeletal muscles work in pairs. Muscles can only pull. When one contracts, the other relaxes.

18. We’re Gonna PUMP You Up To keep muscles healthy, regular exercise is important in maintaining strength and flexibility. Exercise helps the muscle cells grow bigger.

19. Perils of Space Astronauts worry about loss of muscle called atrophy. This is because of weightlessness. There is no force being exerted by the muscles. And as the old saying goes “Use it, or lose it.”
