Functions of the Skeleton The skeleton ___________ the body. The skeleton ___________ soft body parts. The skeleton ___________ blood cells. The skeleton ___________ minerals and fats. The skeleton (along with the muscles) permits flexible body ___________. 2. Classification of bones Bones are classified according to their shape. ___________ (Longer then they are wide) ___________ (Cube shapes, about equal lengths and widths) ___________ (Plate like and have a broad surface) ___________ (Varied shapes with many connections) ___________ (Circular shape) Long Bones- Longer then they are wide) Longest bones providing support for the body giving it the rigidity (hardness) necessary to stand and move. Long bones can act as levers Example: Short Bones- (Cube shaped; lengths and widths are about equal. Found in the joints and serve as hinges. They help cushion shock and protect long bones. Example: Flat Bones (Plate like and have broad surfaces) Example: Irregular Bones- (Varied shapes with many places for connections with other bones) Example: 3. Anatomy of a Long Bone Periosteum Compact Bone Spongy Bone Red marrow Yellow marrow 4. Axial and Appendicular Skeleton The ________________ skeleton lies in the midline of the body and contains the bones of the skull, the vertebral column, and the thoracic cage. (Colored) Vertebrae are divided into five regions ________________ Skeleton Contains the bones of the fore and rear limbs. 5. Joints Bones are joined together at joints. In most instances bones can articulate at the joints. Classified by the way they __________.
