Question
What is the difference between electrical transmission and chemical transmission?
Solution
| Electrical Transmission | Chemical Transmission |
| i. Electrical transmission is mediated by electrical synapses. | i. Chemical transmission is mediated through neurotransmitters. |
| ii. Pre- and postsynaptic neurons' membranes are relatively close together. | ii. A synaptic cleft separates the membranes of pre-and postsynaptic neurons. |
| iii. Across the synapses, electrical current can travel straight from one neuron to the next. | iii. Neurotransmitters play a role in the transmission of synaptic impulses. |
| iv. This transmission is more efficient. | iv. This is a slower transmission. |
