Percussion is the process of creating sound waves on the surface of the body to determine abnormal density of any underlying areas. Palpation is the process of touching the patient to judge the size, shape, texture, and temperature of the body surface or underlying structures. Inspection is the process of looking intently at the patient. Auscultation is the process of concentrated listening with a stethoscope to determine characteristics of body functions.
