2K in and 3 Na out |
|
|
Goldman equation |
|
|
|
Electrochemical equilibrium |
E ion, Nernst |
|
|
EMF |
difference between Vm and Eion Current |
|
|
Nernst value for Na |
60 |
|
|
nernst value for k |

|
|
Conductance |
Ability of current to move through – specific toions – reciprocal of resistance so 1/ohms – myelin is membrane of glial cell sono ion movement so resistance would be very high and so no current orconductance |
|
|
Mylein sheath |
only in white matter |
|
|
Nodes of ranvier are opened by |
volatage gated sodium channels |
|
|
in chemical synapse |
AP reaches terminal changes in Vm activate voltage gated Ca channels Ca influx causes transmitter to be released |
|
|
requirements for neutrotransmitter |
must act rapidly change in Vm synthesized and released resynapse have receptor of post cell |
|
|

somatic sensory Visceral sensory special sensory |
|
|
efferent |
somatic and autonomic motor like sympathetic and parasympathetic
|
|
|

ACh |
|
|
Autonomic system consist of |
parasympathetic and sympathic |
|
|
types of receptors for sym and parasymp |
Nicotine ACh R
|
|
|
Post ganglionic transmitter of symp |
