Name a non-selective irreversible alpha antagonist.
Name a non-selective Beta-agonist.
Name a beta receptor antagonist.
Name 2 types of glutamate receptors.
Name a AMPA agonist.
Name a AMPA antagonist.
Name a NMDA agonist.
Name a NMDA antagonist.
Name 2 types of GABA receptors.
Name a receptor for glycine.
Name a glycine receptor agonist.
Name a glycine receptor antagonist.
Name the 2 main mechanisms by which glutamate is removed from the synaptic cleft.
diffusion into the presynaptic nerve terminal
uptake by glial cells (astrocytes)
Briefly describe uptake of glutamate by the glial cell.
Glutamate is taken into the astrocyte by a glutamate transporter. It is converted into glutamine by glutamine synthetase and then sent to the presynaptic nerve terminal by glutamine transporters. It undergoes reactions in the presynaptic nerve terminals to be converted back to glutamate.
What type of receptors are found on muscle cells?
What type of receptors are found on the organ walls for the PNS?
ACh acts on _____ receptors in salivary, lacrimal, and other exocrine glands to _____ fluid and enzyme secretion.
ACh acts on _____ receptors in smooth muscle cells in gut walls, iris, ciliary body, bronchiolar muscle and bladder to _____ contraction.
ACh acts on _____ receptors in cells in stomach to _____ acid secretion.
ACh acts on _____ receptors in cardiac pacemaker to cause _____.
slowing of heart
ACh acts on _____ and _____ receptors in cerebral cortex and hippocampus to produce excitatory responses.
ACh acts on _____ receptors in cerebral cortex and hippocampus to produce inhibitory responses.
Most actions of ACh in brain are at _____ receptors. However, _____ receptors are found in terminals of the "brain reward circuit."
Fall in intracellular [cAMP] causes _____ of Ca2+ channels.
