Q

how does the NS compare to the endocrine system

25
what is the energy source of a message transmission
ATP
26
what kind of response does a message carry
all or none
27
polarized nerve
resting potential
28
where are NA+ and K+ in a polarized nerve
NA+ outside | K+ inside
29
what is NA+
sodium
30
what is K+
potassium
31
where are NA+ and K+ in a depolarized nerve

32
what happens during the stages of a depolarized nerve
- imbalance of ions and acetycholine released into synapse (bubbles released) - contraction of muscles
