Step 1: Begin by understanding the classification of bones based on their shapes. Bones are categorized into five main types: long bones, short bones, flat bones, irregular bones, and sesamoid bones.
Step 2: Review the characteristics of flat bones. Flat bones are typically thin, flattened, and often curved. They serve as protection for internal organs and provide large surfaces for muscle attachment. Examples include the sternum, ribs, and certain skull bones.
Step 3: Identify the parietal and frontal bones in the human body. These bones are part of the skull and form the cranial structure, protecting the brain.
Step 4: Compare the shape and function of the parietal and frontal bones to the characteristics of flat bones. Note that these bones are thin and curved, aligning with the definition of flat bones.
Step 5: Conclude that the parietal and frontal bones are classified as flat bones based on their structure and function.
