2. INTRODUCTION It is usually the initial part of a general physical exam, after the vital signs. It is usually the initial part of a general physical exam, after the vital signs. It begins with inspection, and then proceeds to palpation. It requires the use of several special instruments in order to inspect the eyes and ears, and special techniques to assess their special sensory function.

Use a gloved hand, and warn the patient that you may inadvertently gag him. Use a gloved hand, and warn the patient that you may inadvertently gag him. Gently palpate the surface of the lesion with one or two fingers to assess its size, consistency (soft, firm, hard), underlying induration and tenderness.
