What is the name of the process through which one neuron receives communication
from several other "upstream" neurons?
convergence
Ligand-gated ion channels, such as the nicotinic cholinergic receptor activated by
acetycholine, __________.
allow the influx of sodium ions, which facilitates fast responses at synapses
Which of the following synapses function as modulatory synapses?
dendrosomatic
axosomatic
axoaxonic
axodendritic
axoaxonic
Enkephalin is a neuropeptide that initiates a "slow" response in the postsynaptic cell; to
which type of receptor does enkephalin bind?
metabotropic receptors
Which of the following neurotransmitters does NOT belong to the biogenic amines?
oxytocin
dopamine
, epinephrine
serotonin
Oxytocin
The activation of beta2 receptors in the bronchi causes bronchodilation (an increase in
diameter of the bronchi), making it easier to breathe. Which of the following
neurotransmitters would be useful for a person suffering from an episode of
bronchoconstriction (a reduction in the diameter of the bronchi)?
vasopressin (or ADH)
acetylcholine
epinephrine
oxytocin
epinephrine
Which of the following enzymes catalyzes the synthesis of acetylcholine from acetyl
CoA and choline?
monoamine oxidase (MAO)
catechol-O-methyltransferase (COMT)
choline acetyl transferase (CAT)
acetylcholinesterase (AChE)
