What function do the Krause end bulbs serve?

  1. Detect humidity

  2. Detect temperature

  3. Pressure and pain sensation

  4. Detect light touch

The correct answer is: Pressure and pain sensation

Krause end bulbs serve the function of detecting pressure and pain sensations. They contain sensory nerve endings that respond to mechanical stimuli, such as pressure or stretching of the skin. The other options are incorrect because A) humidity is typically detected by specialized cells in the nasal passages, B) temperature is detected by sensors in the skin or hypothalamus, and D) light touch is detected by specialized receptors called Merkel cells. Therefore, the correct function of Krause end bulbs is to detect pressure and pain sensations.
