All muscular movement accomplished by release of ACE
Appears to be involves in regulating REM sleep, perceptual learning and memory

Question 6

What are the two different types of Monoamine neurotransmitters?

Answer 6

Indolamines & Catecholamines

Question 7

What are the indolamine neurotransmitters?

Answer 7

Serotonin

Question 8

What are the Catecholamine neurotransmitters?

Answer 8

Dopamine
Norepinephrine
Epinephrine

Question 9

Main functions of Dopamine?

Answer 9

catecholamine
excitatory/inhibitory
roles in pleasure, sex, laughter, food. Movement, attention, learning, reinforcing effects of abused drugs.
Synthesized from tyrosine that we obtain from our diet (bananas/thai)

Question 10

main function of norepinephrine?

Answer 10

Noradrenaline
catecholamine
Found in the brain and in the sympathetic division of the autonomic nervous system.
mobilises body for action

Question 11

What is the main function of epinephrine?

Answer 11

adrenaline
Catecholamine
A hormone secreted by the adrenal medulla
Serves as a neurotransmitter in the brain.

Question 12

What is the difference between epinephrine & norepinephrine?

Answer 12

Noradrenaline has a more specific action working mainly on specific receptors to increase and maintain blood pressure whereas epinephrine has more wide-ranging effects. Norepinephrine is continuously released into circulation at low levels while epinephrine is only released during times of stress.

Question 13

What is the main function of serotonin?

Answer 13

plays a role in the regulation of mood, the control of eating, sleeping, dreaming and arousal.
Regulation of pain

Answer 14

Glutamate
GABBA
Glycine

Question 15

What is the main function of Glutamate?

Answer 15

also called glutamic acid

most important excitatory neurotransmitter in brain

Question 16

Main function of GABBA?

Answer 16

most important inhibitory neurotransmitter in brain

Question 17

Main function of Glycine?

Answer 17

Most important inhibitory transmitter in lower brain stem and spinal cord

Question 18

What are peptides?

Answer 18

Peptides are a class of neurons. 
A neuron manufactures both peptides and the enzimes that are needed to break them apart. most peptides appear to serve as neuromodulators. Some act as neurotransmitters

Question 19

What does a neuromodulator do?

Answer 19

diffuse through large areas of the nervous system, modulating the effect of neurotransmitters.

meaning to exert or have a controlling effect on neurotransmitters

Question 20

What are the two types of peptides?

Answer 20

Engoenous opioid (endorphines)
Enkephalin

Question 21

main funtion of Endognous opioid?

Answer 21

Endorphones
A class of peptides secreted by the brain that acts as opioids
inhibit transmission of pain signals
