exam questions with answers |\ |\ |\
if the membrane potential of a neuron changes from -65mV to -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
75mV... - CORRECT ANSWERS ✔✔the membrane is now more
|\ |\ |\ |\ |\ |\ |\ |\ |\
polarised
when voltage-gated Na+ channels are opened, Na+ ions rush into
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the neuron. The force driving this movement into the cell is: -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔primarily due to the diffusion gradient
|\ |\ |\ |\ |\ |\ |\ |\
across the cell membrane
|\ |\ |\
At rest, - CORRECT ANSWERS ✔✔the extracellular region is more
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
positive than the intracellular region of a neuron
|\ |\ |\ |\ |\ |\ |\
communication within the central nervous system - CORRECT |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔is dependent on both electrical and chemical
|\ |\ |\ |\ |\ |\ |\ |\
processes
'Always Open' ion channels are also called - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
✔✔non-gated ion channels |\ |\
,what is the more important for communication between neurons? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔chemical processes |\ |\ |\
when a Na+ channel is opened, Na+ ions rush into the neuron.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
This results in... - CORRECT ANSWERS ✔✔either no effect on, or
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
inhibition or excitation of the subsequent neuron, depending on |\ |\ |\ |\ |\ |\ |\ |\ |\
other factors |\
Opening a ligand-gated sodium (Na+) channel will - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔depolarise the cell membrane |\ |\ |\ |\
functions of the membrane - CORRECT ANSWERS ✔✔it allows the |\ |\ |\ |\ |\ |\ |\ |\ |\
passage of specific ions into and out of the neuron; it maintains the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
resting membrane potential; it allows controlled changes to the
|\ |\ |\ |\ |\ |\ |\ |\ |\
membrane potential |\
ions, or small charged molecules - CORRECT ANSWERS ✔✔they
|\ |\ |\ |\ |\ |\ |\ |\ |\
are similar to other electrically charged objet in so far as similarly
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
charged ions repel, whereas those with opposite charges attract each
|\ |\ |\ |\ |\ |\ |\ |\ |\
other
|\
an inverse agonist - CORRECT ANSWERS ✔✔decreases activation
|\ |\ |\ |\ |\ |\ |\ |\
of a receptor
|\ |\
, opening a ligand-gated sodium )Na+) channel will - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔depolarise the cell membrane |\ |\ |\ |\
partial agonists - CORRECT ANSWERS ✔✔can either increase or
|\ |\ |\ |\ |\ |\ |\ |\ |\
decrease ion channel activity, depending on other factors
|\ |\ |\ |\ |\ |\ |\
categorising receptors into serotonergic, dopaminergic etc, is an
|\ |\ |\ |\ |\ |\ |\ |\
example of - CORRECT ANSWERS ✔✔pharmacological subtyping
|\ |\ |\ |\ |\ |\
allosteric modulation (AM) and/or co-transmission (CT) -
|\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔for AM to affect ion channel opening, the
|\ |\ |\ |\ |\ |\ |\ |\ |\
ion channel receptor must also be activated
|\ |\ |\ |\ |\ |\ |\
categorising receptors into G-protein linked receptors and ligand-
|\ |\ |\ |\ |\ |\ |\
gated ion channel receptors, is an example of - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔receptor superfamilies |\ |\
Type of drugs used to treat anxiety disorders? - CORRECT
