Verified step by step guidance

Begin by understanding the function of each type of receptor mentioned in the problem. Receptors are specialized cells or nerve endings that respond to specific stimuli and send signals to the brain.

Photoreceptors are responsible for detecting light and are primarily found in the eyes. They help in vision but do not alert the brain about damage to the body.

Thermoreceptors detect changes in temperature. They are involved in sensing heat and cold but are not directly responsible for signaling damage.

Mechanoreceptors respond to mechanical pressure or distortion. They are involved in sensing touch, pressure, and vibration but are not specifically for detecting damage.

Nociceptors are specialized receptors that detect pain. They are activated by potentially damaging stimuli, such as extreme pressure, temperature, or chemical changes, and alert the brain to potential harm or injury.
