Oral cavity in a bisected cadaver. The vestibule is lateral to the teeth. Notice the large fourth premolar (asterisk). Within the oral cavity proper, the tongue (1) is reflected and floor mucosa has been incised to reveal the polystomatic sublingual salivary gland (2) and mandibular and sublingual salivary ducts (3) emptying at the sublingual caruncle (4). On the tongue, notice vallate papillae (5) and fungiform papillae (6) amidst a sea of filliform papillae.

Also notice: hard palate (7), soft palate (8), epiglottis (9), and the border (10) between the pharynx (11) and esophagus (12).
