make an impulse in the next neuron more likely

make an impulse in the next neuron less likely

Question 19

Answer 19

chemical messengers releaaed when a nerve impulse reaches the end of one neuron

Question 20

Answer 20

chemicals produced by the endocrine glands

Question 21

what are the strengths of the biological approach

Answer 21

-one of the most scientific approaches
-has useful applications

Question 22

what are the useful applications of the biological approach

Answer 22

biological treatment (e.g surgery or drug treatment)

Question 23

what are the limitations of the biological approach

Answer 23

-deterministic (ignores free will)
-socially sensitive

Question 24

why is research into biology socially sensitive

Answer 24
