Skeletal and Muscular Systems Functions_of_the_Skeletal_System.asf by Janet Baity The 5 Functions: 1. Skeleton gives us structure and support 2. Skeleton protects the internal organs 3. Skeleton provides a place for muscles to attach 4. Red blood cells are made inside bones in tissue called marrow 5. Skeleton stores compounds such as calcium and phosphorus Structure and Support Protection Parts of Bone 1. Periosteum 2. Compact (hard bone) 3.Cancellous (spongy) bone 4. Bone marrow bone.html Draw the bone and label the parts 206 bones make up your skeleton system. Bones contain minerals such as calcium and phosphorus. These help give bones their strength. Muscles attach to the skeleton The_Muscular_System.asf Muscle Action in the Skeletal System Working in opposing pairs, muscles serve to move the bones. Bones are connected to muscles by thick bands of connective tissue, known as tendons. When muscles contract (become shorter) and relax ( become longer), they pull on the bones making movement occur.
