- Substance P
Which neurotransmitter is an adregenic synapse and has an excitatory effect on the target tissue?
Which neurotransmitter is excitatory to the brain and inhibitory to the muscles?
Which neurotransmitter is a cholinergic synapse and is inhibitory for most tissue except for muscle?
Inadequate concentrations of this neurotransmitter are linked to depression.
Substance P plays a role in _______ pathways.
True or False: The more substance P you have in your body, the more pain you feel.
This neurotransmitter can act as an endogenous morphine by blocking the release of substance P.
