Skeletal and Muscular Systems

Discover skeletal & muscular systems! Learn about bones, muscles, and joints with this science worksheet.

Levels of Organization Use these words: tissue, organ, organ system, cell cell tissue organ organ system Which of the following is NOT a function of the skeletal system? Heat production. Movement Shape support Stores calcium What is the function of the Marrow found within your bones? Is found at the end of bones to reduce friction. Connects your bone to another bone. Makes red blood cells, white blood cells, and platelets. Skeletal System Structure Matching Match each structure of the skeletal system to its description. Immoveable (fixed) Does not move (skull.) Pivot Movement around a point (neck.) Ball and Socket Allows 360 degree motion (shoulder and hip) Hinge Allows for open and close motion (knees and elbows.) Sliding Bones that glide past one another (hands and feet.) What is cartilage? The inner part of the bones that makes red blood cells, white blood cells, and platelets. Tissue that connects one bone to another bone. Where two bones meet. Flexible connective tissue that is found on the ends of bones to reduce friction. Using the image above, your ACL and MCL are considered what? Hint: They connect a bone to another bone. Tendons Cartilage Ligaments Marrow Which is NOT a function of the muscular system? Generate heat Aid in movement Produce blood cells Maintain posture Sort the characteristics of the three types of muscles. Smooth Muscle Involuntary Movement Walls of Internal Organs Skeletal Muscle Voluntary Movement Works in Pairs Cardiac Muscle Found in the heart Involuntary contractions When your muscles are fatigued, they have used up the available Carbon dioxide Oxygen Nitrogen Water
