What is the difference between electrical transmission and chemical transmission?
✓

Answer

Differences between electrical transmission and chemical transmission are:
 
Electrical transmission
Chemical transmission
i.
Electrical synapse is present.
Chemical synapase is present.
ii.
Membranes of pre-and post-synaptic neurons are in very close proximity provided by the gap junction.
The membranes of pre-and post-synaptic neurons are separated by a fluid-filled space called synaptic cleft.
iii.
Impulse transmission across an electrical synapse is fast.
Impulse transmission across a chemical synapse is slow.
iv.
No neurptransmitter is involved.
Neurotransmitter is involved.
v.
Electrical synapase are relatively rare.
Chemical synapses are relatively more.
