The Skeletal System • • • • • • Long Bones--They serve as support columns. They assist the animal in body support, locomotion, and eating. Example: Femur Short Bones--They are shaped like a cube and are located in complex joints such as the knee and hock. They diffuse concussion and diminish friction. Example: Hock Flat Bones--They protect vital organs such as the brain, heart and lungs. They are longer and wider than they are thick. Example: Scapula Pneumatic bones--they contain air spaces called sinuses that are in contact with the atmosphere. Example: Frontal face bones. Irregular Bones--important to the protection and support of the central nervous system and are points of some muscle attachment. Example: Vertebrae Sesamoid Bones--they are flat and round. They are located along the course of tendons. Example: Kneecap or patella Bone Types To complete the worksheet, draw the following bones and give an example of each from an animal or human skeleton. 1. Long Bones 2. Short Bones 3. Flat Bones 4.
