Ch 6 - Functional Properties of Neuron

Question 0

conductance equation

Answer 0

g = sigma x cross sectional area/length

Question 1

this force creates a potential difference and it is measured by work

Answer 1

electrostatic

Question 2

bad conductor

Answer 2

lipid

Question 3

conductance is also =

Answer 3

1/ resistance

Question 4

current (A) formula

Answer 4

current (Amps) = potential difference (Volts) x conductance (Siemens)

Question 5

current is usually the flow of ions from blank to blank

Answer 5

positive, negative

Question 6

work formula

Answer 6

= force x distance

Question 7

amount of energy that needs to be overcome combined with the electrostatic energy of the capacitor

Answer 7

force

Question 8

increasing surface area of the axons, the greater the blank because there is more room for blank

Answer 8

capacitance, charge

Question 9

if the plates of a capacitor are farther apart, then more blank must be done because the blank is lower

Answer 9

work, capacitance

Question 10

important passive property of the neuron that is the distance where the initial voltage response decays to 37 percent of its initial value

Answer 10

length constant

Question 11

length constant formula

Answer 11

wavelength = sqrt(rm / ro + ri)

Question 12

time constant equation

Answer 12

t = rm x cm

Question 13

large cells have blank time constants

Answer 13

short

Question 14

small cells have blank time constants

Answer 14

long

Question 15

ion channels can be thought of as blank

Answer 15

resistors

Question 16

ion channels allow for the blank property of the membrane

Answer 16

leaky

Question 17

conductance is related to

Answer 17

current and voltage

Question 18

no current means there is an equilibrium of blank and blank gradients

Answer 18

electrical, chemical

Question 19

wide and short axons have blank conductance and blank resistance???

Answer 19

high, little

Question 20

nodes of ranvier are not blank

Answer 20

myelinated
