Levels of Organization Use these words: tissue, organ, organ system, cell tissue cell organ organ system muscle tissue Can contract or shorten, enables the body to move. connective tissue Supports your body and connects its parts. epithelial tissue Covers the surface of the organs and the body. (skin) nervous Used for directing and controlling reactions to stimuli Skeletal System Structure Matching Match each part of the skeletal system to its description. Joints Allow the body to move and bend Ligaments Connect bones together Tendons Attach muscle to bone Cartilage A stretchy but strong substance that makes up joints Marrow The filling of the bone Growth Plate The part of the bone that stretches and grows during development Which of the following is NOT a function of the skeletal system? Heat production. Movement Support Protection 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. 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? Protection Aid in movement Produce blood cells Maintain posture Fill in the blanks from the word bank provided. 1. Your muscular system is the body system that helps you to move and maintain your posture.2. A point at which two of your bones meet is a joint.3. Tough tissue fiber that connects muscles to bone is called a tendon.4. The support framework for your body is your skeletal system .5. The soft material on the end of your bones is cartilage.6. Your heart is a(n) involuntary muscle, which means that you cannot control its function.7. Skeletal muscles only pull in one direction. For this reason they always come in pairs. 8.When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the opposite direction to straighten the joint out again. Sort the characteristics of the three types of muscles. (2 in each category) Smooth Muscle Involuntary Movement Walls of Internal Organs Skeletal Muscle Voluntary Movement Works in Pairs Cardiac Muscle Found in the heart Involuntary contractions
