NEURON = FONCTIONNAL UNIT OF SNC

Excitable
and secretory cell
|
|
|
|
|
|
 |
 |
 |
The
second excitory pathway
|
|
increases
the size of depolarization, so
|
that
the threshold for spike generation
|
|
is reached
|
|
|
|
|
|
 |
 |
Inhibitory
pathway prevents
|
the excitory
potential from
|
|
|
reaching threshold
