Neurotransmitters

Question 1

Acetylcholine

Answer 1

Acetylcholine: mostly excitatory but inhibitory neuromuscular synapses at heart. Activates all voluntary muscles

Cns: throughout brain
Pns: neuromuscular junctions (voluntary muscles) sympathie nervous system, oarasymlathy

Excitatory at neuromuscular junctions

Inhibitory between the vagus nerve and cardiac muscle

Question 2

Norepinephrine

Answer 2

Excititory: attention/consciousness, temperature control and pituitary gland secretion

found in brain, spinal cord, neuromuscular and neurglandar junctions of the sympathic nervous system

Question 3

Dopamine

Answer 3

Excitatory (amplified by cocaine) and inhibitory (involved in precise movement control)

found in hypothalamus, midlebrain, limbic system, cerebral cortex, retina

Question 4

Sérotonine

Answer 4

Excitatory and inhibitory

Attention and emotional states
Selective sérotonine récup take inhibitors (SSRI)
Ecstasy
People with depression have a problem here, either too little or a resistance

found in hypothalamus, cerebellum, spinal cord, retina

Question 5

GABA

Answer 5

inhibitory: anti anxiety effects

found in cerebral cortex, cerebellum, interneurons in spinal cord

Question 6

Glutamate

Answer 6

main neurotransmitter Excitatory: memory and learning

cerebral cortex brainstem
