Finger-like process viewed at different tilts exposes different regions of preserved membranes (73 years old). A. At 0° tilt, the percentage of the perimeter displaying at least one membrane is 48%. Some ECS deposits are noted (yellow) on the concave side of curved membranes. Other dark staining material may also be deposits but the membranes are not visible. B. Tilting the grid to 40° (counterclockwise) exposes more membranes, now measuring about 65% of the perimeter. More ECS deposits are also indicated. The tilt axis is vertical, thus the finger-like process appears proportionally shorter in projection.
