How do electrical impulses go across synapses?
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
Why nerve signal cant go backward?
Nerve signals cannot go backward primarily due to the refractory period that follows an action potential. After a nerve impulse travels along an axon, the sodium channels that opened during depolarization close and become temporarily inactivated, preventing another action potential from occurring immediately in that section of the membrane. Additionally, the directional flow of signals is aided by the structure of neurons, where the synapse only transmits signals in one direction—from the presynaptic to the postsynaptic neuron. This combination of biochemical and structural factors ensures that nerve impulses propagate in a forward direction.
What is the correct order that information passes through in a neuron?
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.
How do livng things respond to stimuli?
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.
What is the only direction you can go from North Pole?
The only direction you can go from the North Pole is south.
State why there is a brief delay in the transmission of an impulse across the synapse?
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.
What direction does nerve impulse travel?
Along a nerve cell, the impulse travels from the axon to the dendrites and then again to the axons through the synapse.
How do electrical impulses go across synapses?
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
Is Europe northeast or northwest of Australia?
Both. Depending on which direction you are looking from. You could either go northeast across Canada, or northwest across Africa.
Which direction would you go to travel from the pacific ocean to the Atlantic ocean?
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.
What direction would you go if you come from china to the US across the pacific ocean?
East
What part of nervous system transmit message?
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.
What direction would you be traveling if you go la grange to Sydney?
If you flew across Australia from LaGrange to Sydney, in what direction would you be traveling?

In which direction would you travel to go from shanghai to mumbai?
southwest
What direction would you go to get from north America to Europe?
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.
