Question

The simplest receptors are the dendrites of sensory neurons, called ________.
A) Merkel cells
B) lamellated corpuscles
C) Ruffini corpuscles
D) free nerve endings
E) tactile discs

Accepted Answer

Free nerve endings are the simplest receptors and are found in the dendrites of sensory neurons. They are responsible for detecting pain, temperature, and pressure. Merkel cells, lamellated corpuscles, Ruffini corpuscles, and tactile discs are all more complex sensory receptors found in the skin.
