Science Study Guide: The Human Body

Skeletal System: All the bones in our body, they give our body shape

Protection Bones : Bones that guard other body partso Examples: Ribs, Skull, Pelvis

Movement and Support Bones : Bones that help us walk, touch, turn and stand

o Examples: Femur, Humorous, Tibia, Fibula, Radius, Ulna

Joints: The place where two bones come together

Hinge : Ball-and-socket : Gliding :

Muscular System:All of the muscles in your body that allow you to move, run and jump

Muscles: Tissue that contracts and expands to let you body move Contract: To get smaller

Bones: A hard material that is made of mostly calcium that makes up the skeleton.

Skull : Protects your brain Femur : The longest bone in your body. It is between the knee and the

hip. It attaches to the hip with a ball-and-socket joint. Ulna : One of two bones that make up our lower arm (between elbows

and wrist) Radius : One of two bones that make up our lower arm (between elbows

and wrist)

Key Concepts: Without bones, our bodies would not hold their shape Dogs and cats have skeletal systems that are a lot like people One good way to measure how long your bones are getting is to use a meter

stick Muscles are strong and move the bones when we walk or run

**Also, study the Skeleton Diagram on the back. Be sure to know the important labels for bones.
