Make note of the two types of epithelial tissue found in the soft palate. What does parakeratinized mean? There should be an abundance of mucous glands here. Look for the presence of skeletal muscle in the soft palate region. Note that the lamina propria is very cellular containing lymphocytes and plasma cells.

This is a low power image of the Soft Palate. The first thing that you can see is the abundance of Mucous Glands under the surface of the epithelium indicated by the red arrows. The blue arrow is pointing to the Lining Mucosa which is what lines the soft palate. Lining mucosa is a Stratified Squamous Non-Keratinized epithelium.
Red arrow - Mucous Glands Blue arrow - Lining Mucosa
Here is a closer look at the Lining Mucosa indicated by the white arrow. In this view you can see the nuclei still present in the top layer of the epithelium. Also note less number of dermal papillae and rete ridges. The blue arrows are pointing out the characteristic mucous glands that are usually associated with the soft palate and the lining mucosa. SO, if you see a stratified squamous non-keratinized with mucous glands associated with it, you can safely assume that it is the hard palate.
