16
Q

resting membrane potential

A

-70mV

17
Q

graded potential

A

within dendrites the PULSE - can vary in SIZE

18
Q

spatial or temporal summation

A

integration of information occur in dendrites

19
Q

all or none - action potential

A

within axons - PULSE

depends if it reaches a THRESHOLD level of intensity at the initial segment

20
Q

tetrotoxin (TTX)

= poison

A
  • 10,000 deadlier than cyanide
  • approximately 200 cases of poisoning
  • blocks ion flow- through channels that generate action potentials.
