Verified step by step guidance1
Begin by understanding the function of sensory receptors. Sensory receptors are specialized cells or nerve endings that respond to specific types of stimuli and send signals to the brain for interpretation.
Identify the types of sensory receptors mentioned in the problem: chemoreceptors, thermoreceptors, photoreceptors, and mechanoreceptors.
Chemoreceptors are responsible for detecting chemical stimuli, such as changes in the concentration of substances like oxygen or carbon dioxide in the blood.
Photoreceptors are specialized for detecting light and are primarily found in the retina of the eye, playing a crucial role in vision.
Mechanoreceptors respond to mechanical stimuli such as pressure, vibration, and touch. Thermoreceptors, on the other hand, are specifically designed to detect changes in temperature, making them the correct type of receptor for this problem.
