Final answer:
In terms of vulnerable areas, there are four different zones of touch: safe zone, caution zone, danger zone, and restricted zone.
Step-by-step explanation:
Touch is the ability to sense pressure, vibration, temperature, pain, and other tactile stimuli. The skin includes several different types of touch receptor cells. These receptors are especially concentrated on the tongue, lips, face, palms of the hands, and soles of the feet. Different areas of the body can be classified into four zones:
- Safe zone: This is where touch is welcome and comfortable. It includes areas like the back of the hand or the forearm.
- Caution zone: This is where touch should be approached with care. Examples include the stomach or the back of the neck.
- Danger zone: This is where touch is not allowed and can cause harm. It includes areas like the genitals or the eyes.
- Restricted zone: This is where touch is strictly prohibited. Examples include areas like the breasts or the buttocks.
