Which of the following statements about transmission of nerve impulse is incorrect?
1
Nerve impulse travels from dendritic end towards axonal end
2
At the dendritic end, electrical impulses bring about the release of some chemicals which generate an electrical impulse at the axonal end of another neuron
3
The chemicals released from the axonal end of one neuron cross the synapse and generate a similar electrical impulse in a dendrite of another neuron
4
A neuron transmits electrical impulses not only to another neuron but also to muscle and gland cells
