- option a is incorrect as morphine activates the GABAergic neurons in the VTA, So, all the above are not correct.
- Option b, c and e are incorrect as the first statement is not correct.
- Option d is correct as statement 2, 3 and 4 are correct.
CORRECT STATEMENTS
Statement 2 morphine decreases the concentration of dopamine by reverse microdialysis.
Statement 3 morphine inhibits emesis centre by antagonising D2 receptors and D2 receptors are those which informs emesis centre about emetic agents.
Statement 4 morphine increases the tolerance of ant-nociceptors in the patient by re-uptake of 5HT.
