Final answer:
During an extraoral examination, the parotid, submandibular, and sublingual glands are assessed, while the minor salivary glands are not.
Step-by-step explanation:
The salivary glands play an important role in producing saliva, which helps lubricate food and initiate the breakdown of carbohydrates. During an extraoral examination, the three major pairs of salivary glands that are assessed include the parotid gland, submandibular gland, and sublingual gland. The exception is the minor salivary glands, which are smaller glands housed within the mucous membranes of the mouth and tongue.
