This section shows ciliated cells (Ci), a few goblet mucous cells (+) with lightly stained mucigen granules and basal cells (B) applied to the lamina propria.

In the underlying dense lamina propria numerous cross sections of elastic fibres are stained black (vertical arrows).

In the looser connective tissue (bottom) a few longitudinal views of elastic fibres (red arrows) are seen in addition to the acidophilic collagen fibres.

Small vessels (V) are also labelled.
