What type of potential is generated in the post-synaptic neuron as...
Options
- AA new potential
- BAn electrical current
- CAn inhibitory potential
- DAn excitatory potential
Correct answer
D. An excitatory potential
Step-by-step solution
The action potential is generated in response to a stimulus and travels along the length of the axon, transmitting the nerve impulse. The rise in permeability to Na⁺ is short-lived and is followed by a rise in permeability to K⁺. K⁺ diffuses outside the membrane, restoring the resting potential of the membrane. The new potential developed in the post-synaptic neuron as a result of neurotransmitter binding to specific receptors may be either excitatory or inhibitory.Impulse travels faster in electrical synapseThe brain acts as the "command and control system" and controls various functions such as voluntary movements, balance, vital organs, circadian rhythms, endocrine glands and human behavior
