Answer 14

peripheral adaptation

Question 15

two receptors of peripheral adaptation

Answer 15

fast adapting, slow adapting

Question 16

sensory adaptation where sensory neurons are still active and CNS causes reduced perception

type of pain that is visceral pain that feels like it is coming from a more superficial region

Answer 37

referred pain

Question 38

example of a referred pain

Answer 38

brain freeze

Question 39

referred pain is due to blank structures being innervated by the same blank nerves as the damaged viscera
