QUESTION 1
1. Select the neurotransmitter involved in obsessive-compulsive disorder (OCD) in
children and adolescents based on the common comorbidity of tic disorders.
A Norepinephrine
B
GABA
.
C
Dopamine
.
D Acetylcholine
Answer:
Dopamine
Obsessive-compulsive disorder (OCD) is linked to defects in the cortico-striatal-thalamic-cortical (CSTC)
circuitry, which may be linked to neurotransmitter dysregulation throughout this network. Serotonin,
dopamine, glutamate, and -aminobutyric acid (GABA) are the main neurotransmitters throughout the
CSTC.
Compulsive behaviors linked to OCD are likely the product of a related dopaminergic reward
system dysfunction. Continuous ventral striatum activation may lead to an undirected expectation of
reward. Anxiety and a desire to fill the gap are caused by unfulfilled expectations.

Opioids analgesics
, Opioid analgesics are drugs that function on opioid receptors that are used to alleviate pain. Weak opioid
analgesics are often used to describe compound analgesics that combine acetaminophen with low levels
of codeine or tramadol. Opioid analgesics, which include oxycodone, hydrocodone, and codeine, can be
used to relieve mild to extreme acute pain.
Opioids are medications that are chemically similar to, but more potent than, the body's own pain
relievers (endorphins). They operate by binding to receptors on cells, primarily in the brain, spinal cord, and
gastrointestinal tract.
