Solution
Both the olfactory receptor and the free nerve ending can respond to a chemical stimulus.
The olfactory receptor is a sensory cell within the olfactory system and is used for the detection of odor molecules. This process involves the binding of odor molecules to receptors on the cilia of the olfactory receptor cells. This binding triggers an electrical signal that is transmitted to the brain, which interprets the signal as a specific smell.
Free nerve endings are unencapsulated and can be stimulated by several different stimuli, including temperature, pressure, and chemical changes in their environment. They are found throughout the body, especially in the skin and mucous membranes.
The Pacinian corpuscle, on the other hand, is a type of nerve ending that is responsible for sensing vibration and pressure, not chemical stimuli.
So, the answer to your question is: olfactory receptor and free nerve ending.
