Final answer:
Palpation and percussion are techniques used to assess the body, while thermal and electric are techniques used to assess sensory perception.
Step-by-step explanation:
Palpation and percussion are techniques used to assess different aspects of the body. Palpation involves using the hands to feel for abnormalities, such as lumps or swelling, while percussion involves tapping on the body to assess the sound and vibration produced. These techniques are commonly used in medical exams to gather information about the body's condition.
Thermal and electric are techniques used to assess sensory perception. Thermal testing involves applying heat or cold to the skin and assessing how the person perceives the temperature change. Electric testing involves applying a mild electrical current to the skin and assessing the person's response. These techniques are used to assess nerve function and sensory perception.
