Long alt text: The cochlear nerve is one of the innermost parts, extending further inward from the cochlea at the front of the inner ear.
Notice how we only describe positioning of the cochlear nerve, as that was mentioned in the caption and is the focus of the image. The caption and surrounding text will indicate if the full diagram needs to be described or only part.

Next, they identify underlying causes. They then identify remedial actions. After that, they create an investigation report. Finally, they follow up.
Notice how we do not describe the physical appearance of the chart, as the importance is not in the structure but rather in that steps follow a sequence.
