A 37-year-old woman presents with a suspected Schwannoma. The radiology report indicates "a soft tissue mass to the right of L1 at the level of the L1 to L2 neural foramen." The neurologist presses the base of a vibrating $128 \mathrm{cps}$ tuning fork to the skin of the patient's right and left thighs and asks her to describe the sensation. She asks the patient to close her eyes and then to tell her whether the tuning fork is vibrating or not. With that instrument the doctor is primarily testing the function of which of the following sensory receptors?
