Skeletal and Muscular Systems 1L2

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.) Ball and Socket Allows 360 degree motion (shoulder and hip) Hinge Allows for open and close motion (knees and elbows.) Gliding Bones that slide 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 Walls of Internal Organs spindle shaped and involuntary Skeletal Muscle Voluntary Movement Works in Pairs Cardiac Muscle Found in the heart involuntary and branched cells When your muscles are fatigued, they have used up the available Carbon dioxide Oxygen Nitrogen Water Fill in the blank with the words from the wordbank. 1. Bones, ligaments, and cartilage make up the skeletal system.2. Ligaments hold bones together.3. Cartilage is the smooth connective tissue at the end of the bones to cushion the bones from impact and friction.4. Bones are made of minerals, connective tissues, and marrow.5. Calcium is the common mineral in our bones.6. Red marrow is at the center of the bones and produces blood. As a child grows, their bones grow too. The growth of the long bones happens in a plate near the end of each bone. What happens to the cells of cartilage in a growth plate? Cartilage cells are replaced by bone cells. Cartilage cells lengthen to help stretch out the bone. Cartilage cells expand and become spongy bone cells. Cartilage cells move into spongy bone cells. What is the function of tendons? They produce blood cells. They connect bones at a joint. They connect skeletal muscle to bone.
