It should be noted here that anatomical diagrams are very complex, and if you have labeled them correctly, your students will not have a hard time learning them or remembering them. Following is the human skull diagram. In the skull bones labeled diagram, we have shown Parietal, Occipital, Temporal, Mandible, Maxilla, Zygomatic, Lacrimal, Nasal, Ethmoid, Sphenoid, and Frontal. It should be noted here that labeling a diagram serves as useful feedback to a teacher, too, as it provides information about what students understand and what they still need to learn.
