Hormones

Question 1

a neurotransmitter located primarily in the brainstem, has been found to
be involved in the control of complex movements, motivation, cognition,
and regulation of emotional responses.

Answer 1

Dopamine

Question 2

the most prevalent neurotransmitter in the nervous system, is located
primarily in the brain stem and plays a role in changes in attention,
learning and memory, sleep and wakefulness, and mood regulation.

Answer 2

Norepinephrine

Question 3

are also known as noradrenaline and adrenaline, respectively. Excess
norepinephrine has been implicated in several anxiety disorders; deficits
may contribute to memory loss, social withdrawal, and depression.

Answer 3

Epinephrine

Question 4

a neurotransmitter found only in the brain, is derived from tryptophan, a
dietary amino acid.
- The function of serotonin is mostly inhibitory, and it is involved in the
control of food intake, sleep and wakefulness, temperature regulation,
pain control, sexual behavior, and regulation of emotions.

Answer 4

Serotonin

Question 5

The role of histamine in mental illness is under investigation.
- It is involved in peripheral allergic responses, control of gastric
secretions, cardiac stimulation, and alertness.

Answer 5

Histamine

Question 6

is a neurotransmitter found in the brain, spinal cord, and peripheral
nervous system, particularly at the neuromuscular junction of skeletal
muscle. It can be excitatory or inhibitory

Answer 6

Acetylcholine

Question 7

is an excitatory amino acid that at high levels can have major neurotoxic
effects.
- It has been implicated in the brain damage caused by stroke,
hypoglycemia, sustained hypoxia or ischemia, and some degenerative
diseases such as Huntington’s or Alzheimer’s.

Answer 7

Glutamate

Question 8

an amino acid, is the major inhibitory neurotransmitter in the brain and
has been found to modulate other neurotransmitter systems rather than
to provide a direct stimulus
ETHICAL

Answer 8

Gamma-Aminobutyric Acid
