Question

which is an example of a slow - adapting receptor?
touch
smell
temperature
pressure
pain

Explanation:

Slow - adapting receptors continue to respond as long as the stimulus is present. Pain receptors (nociceptors) are slow - adapting. They need to keep sending signals to alert the body of potential or ongoing tissue damage. Touch, smell, temperature, and pressure receptors (many types) are often fast - adapting. For example, touch receptors quickly reduce their firing rate if the touch stimulus is constant (like wearing a watch). Smell receptors adapt to a constant odor, temperature receptors to a constant temperature change, and some pressure receptors to a constant pressure.
