Pain receptors are free nerve endings that respond to tissue damage and display sensory adaptation true or false
ANEK [815]
False.

Pain receptors are free nerve endings- nociceptors- that are stimulated by the chemical released from damaged tissue.
These receptors alert us for possible danger but they don't display sensory adaptation. Sensory adaptation it's when the response to stimulus decreases even though the stimulus is the same, we just become unaware of it.
In pain sensations, that doesn't happen.
