Intro to the Neuron (1)

To the nearest 10 roughly what is the average external Na ion concentration in human neurons? (mM)

To the nearest 5 roughly what is the average internal Na ion concentration in human neurons? (mM)

What is the name of the equation that can be used to determine equilibrium potential when the membrane is permeable to one ion only?

Chloride ions are normally extruded by secondary active processes, when couped to movement of K ions what is the name of the transporter?

When coupled to the sodium-dependant flux of HCO3- ions, what is the transporter?

In an action potential what is the name given to the point where inward current carried by Na+ ions just exceeds outward current across the resting membrane?

What is the most common type of electrical synapse?

Fusion of neurotransmitters with presynaptic membranes for exocytosis is controlled by v (vesicle) and t (target) proteins but what is the name of them?

On the vesicle what is the Ca2+ion sensor called?

What is the name for the protein on the vesicle that binds to the SNAP-25 and syntaxin on the plasma membrane?

What is the name for a receptor which triggers a secondary messenger cascade when stimulated?

What type of receptor has a quicker transmission?

What is the primary excitatory transmitter in the CNS?

GABA is one but what is the other major inhibitory transmitter in the CNS?

What is now considered a gasous neurotransmitter which was known as endothelium-derived relaxing factor?

NMDA and AMPA are both ionotropic glutamatergic channels, but which sometimes allows the entrance of divalent cations (e.g. Ca2+)?
