Question

What do the receptors in the skin for light touch and the receptors in the nose for smell have in common?

A) They both adapt very quickly.
B) They send action potentials to the same area of the brain.
C) They both respond to chemicals.
D) They both respond to pressure.

Answer 1

D) They both respond to pressure.

Receptors in the skin for light touch (Meissner's corpuscles) and receptors in the nose for smell (olfactory receptors) have different structures and functions, but they both respond to pressure. Light touch receptors in the skin respond to the pressure of an object touching the skin, while olfactory receptors in the nose respond to the pressure of odor molecules binding to the receptor cells in the nasal cavity.
