Electric transmission

Question 1

how are messages transmitted through the nervous system

Answer 1

• electrical transmission down presynaptic neuron
• converted into chemical transmission across synapse
• converted back to electrical transmission down post synaptic neuron/ pass down axon

Question 2

full explaination of electrical transmission

Answer 2

1. messages sent electrically in neurons
2. when neurons are in resting state, inside cell is negatively charged compared to outside
3. when neuron is activated by stimulus, inside cell is positively charged for split second causing action potential to occurr
4. eletrical impulse travels down axon to axon terminal

Question 3

what is action potential

Answer 3

short lasting event that triggers start of electrical impulse which travels down neuron
