Which type of receptors are less dense compared to cold receptors but are still present for temperature perception?

Hot receptors, also known as warm receptors, are designed to respond to increases in temperature. They are indeed less densely packed in the skin compared to cold receptors, which are specialized for detecting lower temperatures effectively.

The function of hot receptors includes sensing temperatures that induce warmth, activating thermoregulatory responses to prevent overheating. This lower density means that while they are sensitive to temperature increases, their frequency of activation is less compared to cold receptors, which are more numerous and tuned to detecting cooler temperatures.

Understanding the arrangement and function of these receptors is crucial in the context of sensory perception. The fact that hot receptors are present, albeit in fewer numbers, highlights the body's ability to perceive a range of temperatures for survival and comfort.
