Question 28

What order does neuron impulse go in.

Answer 28

Question 29

SSRIS

Answer 29

increases serotonin

Question 29

beta blockers-

Answer 36

antagonist that blocks epinephrine/norepinephrine

Question 37

antipsychotics

Answer 37

antagonist that blocks dopamine receptors

Question 38

inverse agonist

Answer 38

drugs that bind to the same receptor, but produce opposite affect. Suppress receptor activity beyond simple blocking.

Question 39

GABBA

Answer 39

inverse agonist that causes seizures and anxiety

Question 40

antihistamines

Answer 40

H1 inverse agonists

Question 41

synapse

Answer 41

the small, specialized gap between two neurons (or a neuron and a muscle/gland cell) where nerve impulses are transmitted via chemical neurotransmitters or electrical signals

Question 43

cerebrum

Answer 43

largest part of Brain. Serves as the center for higher-level cognitive functions, it controls conscious thought, voluntary actions, memory, sensory processing, and language.
