It should be noted here that when needed, provide labels and, if applicable, accompanied explanation for each part of the diagram right inside the diagram. This way, the labels, and explanations will be together in an integrated format instead of a split-source format. Labeling a diagram requires applying knowledge of a concept. It is an effective form of self-assessment, enabling students to check their understanding. The following diagram shows the spinal cord of the human body. In the spinal cord cross-section labeled diagram, we have shown Dorsal horn, Visceral sensory nuclei, Somatic sensory nuclei, afferent sensory information, efferent signals to muscles and glands via the ventral root, somatic motor nuclei, autonomic efferent nuclei, ventral horn, ventral root, lateral horn, and dorsal root ganglion.
