1) Similiar to a photo caption, a call out is a label used to identify parts of an illustration. The call out may be a simple bit of text around the perimeter of the illustration with or without a line or arrow tying it to a section of the illustration. Or, a call out may be framed with boxes, balloons, use arrows, bullets, or have some other decorative treatment.
2) A pull-quote or text extract from an article set apart in a larger or contrasting font is sometimes referred to as a call out.
