As a right-hand thumb rule, a label is nothing but a word or phrase assigned to a specific part of a diagram to help the reader identify it. The following diagram shows the Radius Bone Anatomy. As shown in the Ulna labeled diagram, we have shown the Head of radius (articular disk), neck of radius, anterior border, radius, styloid process, articular surface of carpals, anterior surface, medial (interosseous) border, radial tuberosity, the radial notch of the Ulna, and more. 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. It is very easy at EdrawMax Online to label any of your diagrams. Simply add the text icon next to the diagram and start writing. Once you are done with the writing process, you can customize it as per your requirement. In addition to this, you can easily share and export your labeled diagram in multiple formats, like PNG, JPEG, PDF, and more.
