7. By looking in the mouth, what information can be given about the general condition and habits of the patient?
Correct answer:
The dry tongue of dehydration; the brown dry tongue of uraemia; the coated tongue with foetor oris of acute appendicitis; and the typical response of the hypochondriac to the command ‘show me your tongue’, upon which the patient opens his or her mouth to an extraordinary degree and enables the nethermost recesses of the oral cavity to become exposed.
