What is the main role of the hypothalamus?
Regulation of autonomic and endocrine function
Which drug has a large effect on the autonomic nervous system, can depolarize all nicotinic receptor synapses without acetylcholine present, and can cause an increase in blood pressure?

How does a sympathomimetic drug enhance adrenergic function?
By binding to receptors and increasing norepinephrine production and release

What effect does a sympatholytic drug have on adrenergic function?
Interrupts sympathetic activity
What is the second signaling molecule in the adrenergic synapse?
Epinephrine
Which type of receptor does norepinephrine bind to in the adrenergic synapse?

What is the function of norepinephrine in the sympathetic division?
Activates muscarinic receptors of sweat glands and blood vessels
Which branch of the autonomic system reacts to stretch stimuli in the aorta and carotid arteries?
