axon to dendrite
An electrial nerve impulse travels across a synapse by diffusion. The neurotransmitter substance from the pre-synaptic cleft travels across the synapse via diffusion. This is then received by receptors in the post synaptic cleft
The flow of information across nerve cells is called a nerve impulse in which the axons of the cell must depolarize, repolarize and go through a refractory period before reaching the resting potential. At this point, another impulse can occur.
There are two types of responses to stimuli. 1)Deep response which requires integration by the brain such as thinking. 2)Simple response which is done by reflex arc. The reflex Arc is consisted if receptor, sensory neuron, relay neuron, motor neuron and effector which is either muscle or gland. For example in humans. If your hand touches a hot object. Heat receptors in your hand will act as sensor, passing an impulse by generating action potential in the sensory neuron. The sensory neuron passes the impulse to along it till reaching the spinal cord passing the impulse to the relay neuron by a process called synapse. The relay neuron synapse with motor neuron to pass the impulse to it. The end of the motor neuron is connected to the bi-ceps muscle in the arm. As the impulse reaches the end of the motor neuron it passes impulse to the muscle ordering it to contract, thus the hand is removed away from stimulus. This process take a fraction of a second.
The only direction you can go from the North Pole is south.
Periods go across the periodic table. Groups go down.
The impulse must go from one neuron to the next. To do this, it must change from an electrical to a chemical signal, and back to an electrical signal when it reaches the next neuron. Electrical signals are impossibly fast, but neurotransmitters cannot cross a synapse that fast. So, the impulse is at its slowest point when it crosses the synapse.
Along a nerve cell, the impulse travels from the axon to the dendrites and then again to the axons through the synapse.

Both. Depending on which direction you are looking from. You could either go northeast across Canada, or northwest across Africa.
You could go either direction and get there. If you go east across North or South America, you will arrive at the Atlantic. If you go west across Eurasia or the Indian Ocean and Africa, you will arrive at the Atlantic as well.
East
If you flew across Australia from LaGrange to Sydney, in what direction would you be traveling?
Impulses in the cell body (soma) of a neuron and move on along its axon, which conducts the impulse to a synapse at the end of the axon. There neurotransmitters are released into the synaptic cleft, so that the impulse can stop or go on to the next neuron or a gland/motor end plate, depending on the kind of neurotransmitter. Different types of neurotransmitters are: acetylcholine, adrenaline, noradrenaline, serotonine.

To get from North America to Europe you would go East across the Atlantic ocean. If you were in Southern US, or further south, you would have to go North East across the Atlantic to get to Europe.
To go from India to the United Kingdom you would have to go North. This is across the world from each other.
