Based on Figure 50.5 and the text description, which of the following statements about sensory receptors in human skin is correct?

  • A: Receptors that detect gentle pressure and vibration are located in deep skin layers.
  • B: Naked dendrites that respond to temperature or noxious stimuli are located in the dermis.
  • C: Receptors that detect hair movement wind around the base of hairs.
  • D: Receptors that respond to strong pressure are located on the skin surface.

Explanation

Figure 50.5 and the accompanying text explicitly state that "Naked dendrites wind around the base of hairs and detect hair movement." Options A and D incorrectly describe the location of gentle pressure/vibration and strong pressure receptors, respectively. Option B incorrectly places naked dendrites for temperature/noxious stimuli in the dermis, when they are in the epidermis.
