4 Anatomic Zones

The number of anatomic zones the gingiva can be divided into.

Incisive Papilla

A small bulge of tissue at the most anterior part of the hard palate.

Palatine Rugae

Firm irregular ridges of tissues, directly posterior to the incisive papilla.

Hard Palate

The bony whiter anterior arch

Median Palatine Raphe

Midline ridge of tissue that runs the full length of the palate from incisive to the uvula. This overlies the bony fusion of the palate.

Soft Palate

The yellow, looser, and softer posterior part of the palate.

Fungi-Form Papillae

Small mushroom-shaped bumps that are usually bright red. Has taste buds that help perceive different flavors. Associated with taste buds.

Foliate Papillae

Short vertical folds located on the lateral surface of the tongue. Associated with taste buds.

Filiform Papillae

Whitish-bumps that cover most of the dorsal surface. Helps move, grip, and manipulate food. NOT associated with taste buds.

Circumvallate Papillae

Large, dome-shaped bumps arranged in a v-shape on the back of the tongue. Associated with taste, especially bitter flavors. Works in saliva production with the Von Ebners glad.

Inverted V-shaped groove that separates the base of the tongue from the body of the tongue.

Foramen Cecum

Pit-like depression that points backwards toward the pharynx.

Sublingual Gland

Salivary gland that is only mucous, non-capsulated. Aka: Bartholin Duct
