The convergence of visceral and somatic afferent neurons onto the ascending pathways to the brain may produce the phenomenon of
What is referred pain
Phosphofructokinase
what is the rate limiting enzyme
Hexokinase
Glycogen Synthase
What makes glycogen just a little bit bigger
Phosphodiesterase
What degrades cAMP to AMP
PIP2
What second messenger is most likely to be produced by a tyrosine kinase receptor?
the smaller the dendritic field the more precise the location of the stimuli can be realized
What principle enables the precise the location of the stimuli can be realized
An influx of chloride
What could be responsible for the initial decline in voltage from the resting potential -70
Mechanoreceptors
What is found in Meissners Corpuscle
Ligand gated receptor
What receptor is used for dendritic sodium channel responsible for graded potentials.
Refractory period
What factor contributes most to the inhibition of retrograde propagation on the axon
The Goldman Hodgkin Katz equation because the resting potential is a function of numerous ions
How does one determine the resting potential of a cell
Voltage gated channel
What receptor is used for both sodium and calcium channels on the axon
saltatory conduction
A non-excitable glial cell
What kind of cells is a astrocyte
Retrograde Synaptic Transmission
The modulating neuron is sending a ligand that will result in an IPSP to the ascending neurons
What occurs when there is pain signaling to the brain from a pain receptor
Inform the brain a precise location of a stimulus
what is the purpose of lateral inhibition
It stops the light from scattering about the retina
What is the role or purpose of the choroid of the retina
They provide lateral inhibition
What is the role or purpose of the horizontal and amacrine cells of the retina
Dephosphorylation of GTP bound to alpha subunit
What event takes place when a GTP bound alpha subunit binds to Adenylyl Cyclase
A relaxation of the zonal fibers and the lens will become more round, thus enabling focusing objects close to the eye
What occurs when there is parasympathetic innervation to the ciliary muscle of the eye
Axo-Axonic synapses modulate the amount of neurotransmitter sent to the synaptic cleft, whereas Axo-somatic and Axo-dendritic change the graded potentials
In lateral inhibition, what is one different between Axo-Axonic and Axo-Dendritic/Axo-Somatic
Fovea
What is the greatest concentration of cone cells found at
cones axons
What is the first cells of the retina hit by light
