A chemical released by a neuron that effects how a postsynaptic cell or neuron will respond to a neurotransmitter is a:
List the six neurotransmitters discussed in class.
- 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.

parasympathetic nervous system
Which division of the ANS takes over during periods of high stress?
sympathetic nervous system
Are preganglionic fibers myelinated or unmyelinated?
