Match the neurotransmitter systems to the description. Each answer is used once. 1- Neurotransmitter system damaged in Parkinson's Disease 2- Also known as serotonin and important for sleep and mood regulation 3- The major excitatory amino acid neurotransmitter in the brain and important for memory formation. 4- The major inhibitory neurotransmitter in the brain. Drugs that agonize this neurotransmitter system (like alcohol) can give a feeling of physical and mental relaxation. 5- Neurotransmitter system involved in the rewarding (reinforcement) effects of addictive drugs. 6- This neurotransmitter is important for attention, concentration, mood regulation, and alertness. 7- This neurotransmitter is important for neuromuscular junction activity and has receptors targeted by nicotine. 8- Peptide hormone that impacts pain sensation, breathing, and euphoria through three types of metabotropic receptors a. Mesostriatal Dopamine b. Norepinephrine c. Glutamate d. Acetylcholine e. Mesolimbocortical Dopamine f. Endorphins g. GABA h. 5-HT

(e) Mesolimbocortical dopamine -  1st statement

it is damaged in Parkinson's disease    

(h) 5-HT -  2nd statement

serotonin is also known as  5- HT and important for sleep and mood regulation

(c) Glutamate - 3rd statement

Glutamate is in the brain that is essential for memory function.

(g)  GABA - 4th statement

GABA agonizes this neurotransmitter system provides a feeling of physical and mental relaxation.

(a)  Mesostriatal dopamine - 5

the rewarding effect of the addictive drug  involved Mesostriatal dopamine

(b)  Norepinephrine - 6th statement

Neurotransmitter important for attention, concentration, mood regulation, and alertness -  

(d) Acetylcholine  -7th statement

neuromuscular junction requires acetylcholine.

(f) Endorphine - 8th statement

pain sensation impacted by endorphin, a peptide hormone

productive most commonly means: achieving or producing a significant amount or result.

explanation:

productive can also mean:

these depend on how the word productive is used. most likely productive will mean   achieving or producing a significant amount or result.
