A)mechanoreceptors only
B)thermoreceptors only
C)nociceptors only
D)thermoreceptors and nociceptors
E)mechanoreceptors and nociceptors

Question

Quizplus · Accepted Answer

Mechanoreceptors are responsible for sensing pressure, touch, and vibration, which would be activated by the firm handshake. Nociceptors are responsible for sensing pain, which would be activated if the handshake starts to hurt a little. Thermoreceptors are responsible for sensing temperature, but there is no indication that they would be activated by the handshake. Therefore, the best choice is E, as both mechanoreceptors and nociceptors would be activated.
