Answer 8

chemical

Question 9

Answer 9

high temp, acidity, and some chemicals

Question 10

how are receptor potentials like graded potentials?

Answer 10

they trigger opening or closing of ion channels

Question 11

what is the job of a sensory receptor?

Answer 11

convert one form of a signal into another

Question 12

how are sensory receptors classified?

Answer 12

speed of adaption

Question 13

what does “adaptation” mean in speed of adaptation?

Answer 13

receptor stops responding

Question 14

what are phasic receptors? for example, when do they fire, what’s an example, and how rapidly do they adapt to stimulus?

Answer 14

fire w/ change in stimulus

ex. touch

adapt rapidly to a stimulus

Question 15

what are tonic receptors?

Answer 15

constantly know where you are

ex. muscle stretch

adapt slowly and continue to produce APs over the duration of the stimulus

Question 16

what are the two types of sensory receptors that we’ve studied in class?

Answer 16

phasic and tonic receptors

Question 17

phasic and tonic receptors are examples of what?

Answer 17

sensory receptors
