2
Q
Amines and Purines
A
Ach Catecholamines Serotonin Histamine Purines
3
Q
Amino acids
A
Glutamate
Aspartate
Glycine
GABA
4
Q
Peptides
A
More than 1 amino acid bound
Generally GIT hormones
Somatistatin
Gastrin
5

6
Q
Gases
A
Nitric Oxide
Carbon Minoxide
7
Q
Catecholamines synthesis
A
Phenylalanine Tyrosine DOPA Dopamine Noreadrenaline Adrenaline
8
Q
Seratonin synthesis
A
Tryptophan
5-hydroxytryptophan
Serotonin
9
Q
Stiff man syndrome
A
Autoimmunity to GAD
Decreased synthesis of GABA
Increased excitation as GABA is inhibitory
Increased stiffness
10
Q
Glycine
A
Inhibitory
Via Cl influx
Direct inhibition in spinal cord and brain stem
11
Q
Strychnine poisoning
A
Antagonist to glycine
Decreased inhibition therefore increased excitability
Convulsions
Muscular hyperactivity
