FIGURE 2. Number, position, and type of marginal muscle attachment sites as they appear within serial longitudinal sections. Each bar represents a 10 Μm longitudinal section with the number and type of muscle attachment points; open bars indicate mesogleal lacunae, black bars indicate mesogleal pleats. Empty positions indicate missing data due to sectioning artifact. Arrows at transitions from endodermal (dominated by pleats) to mesogleal (dominated by lacunae) and the reverse. Inlay diagram demonstrates plane of microtome blade (dotted lines) against the diameter of the polyp (outer ring) and marginal muscle (broken ring). A.
