synaptic transmission

(choose all correct answers)

•    Its chemical process

• Send signals across synapsp

• Its electrical process.

• Involves neurotransmitters

• Spikes being send along an exon.

Axonal conduction

(choose all correct answers)

•    Its chemical process

• Send signals across synapsp

• Its electrical process.

• Involves neurotransmitters

• Spikes being send along an exon.

-       : Is the signals that travel ((along the dendrites toward the cell body)).

• -       membrance potential

• summation

• Postsynaptic potential PSP

• action potential

Postsynaptic potential PSP

• Graded

• Non - Decremental

• decremental

• Rapid (fast)

• All-or-none.

Action potential

• Graded

• Non - Decremental

• decremental

• slower

• All-or-none.

• A: Excitator

  B: Inhibitory

• A: Inhibitory

  B: Excitator

What we are recording called

• membrane potential

• Threshold of excitation

•  

  axon hillon

tells us how much more positive or negative stuff on the inside compared to the out sides. 

• membrane potential

• Threshold of excitation

•  

  axon hillon

In the resting membrane potention (no signals received) we naturally have

• a negative charge inside the neuron approximately -70mV.

• Positive charge

•  

  0

• A: Excitatory

  B: Inhibitory

• A: Inhibitory

  B: Excitatory
