The nerve impulse travels through and reaches the threshold potential which opens Na+ Channels in the cell membrane. The Na+ ions diffuse into cell. The charges reverse at that point on the neuron,...
No. Impulse is force times time, so 2 Newtons of force applied for 5 seconds is the same as 5 Newtons applied for 2 seconds. Impulse equals change of momentum.
they transmit information through neurotransmitters. At a SYNAPSE (the very small space between the end of one neuron and the beginning of another), an impulse from the first (initiating) neuron...
