Flashcards in Q4 Deck (10):
Which channels underlie the regenerative rising phase of some action potentials?
Why is the driving force of Ca so high?
Because there is a very low concentration within the cell.
T/F: Calcium entry during action potentials is used to trigger or regulate various cell functions.
What is one of the two basic types of cardiac action potential?
Pacemaker or muscle fibers of the ventricle
What does NMJ stand for?
T/F: ACh-gated receptors are only permeable to Na channels.
Inhibitory postsynaptic potentials (IPSPs) in the CNS are primarily due to which neurotransmitter?
T/F: IPSPs "clamp" a cell's membrane potential at a value below threshold making it less excitable.
Inhibitory neurotransmitters cause a conductance increase in which two ions?
K and Cl
