Question: 1 / 495

What type of sensation do Krause end bulbs detect?

Heat

Cold

Krause end bulbs are specialized sensory receptors that are primarily responsible for detecting cold sensations. These mechanoreceptors are found in the skin, particularly in areas like the lips and the external genitalia, as well as in some mucous membranes. They respond to decreases in temperature, contributing to the body's ability to sense changes in environmental temperature.

The structure of Krause end bulbs allows them to detect low temperatures effectively. This is crucial for maintaining homeostasis and ensuring the body can adapt to varying thermal conditions. They are distinct from other receptors, such as those that detect heat, pressure, or pain, each of which has its own specific type of receptor with different functions. Understanding the role of Krause end bulbs in thermal sensation highlights their importance in the sensory processing system of the body.
