What is the neural junction over which a message is transmitted?
The Nerve Synapse
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
How are neurotransmitters affected by meth?
since meth causes neurotransmitters to overstimulate they in time down-regulate to compensate for the increased levels of dopamine being released due to the meth but over time they basically start to shut down from working harder than they are meant to and once a neurotransmitter shuts down it can never function again so meth basically kills neurotransmitters over time
What do the excitatory neurotransmitters do?
Exitatory neurotransmitters, such as acetylcholine and glutamate, bind as ligands to ligand-gated channel proteins. Once these neurotransmitters have binded to these transport proteins, the channel opens between the outside and inside of the cell. Once open, sodium (Na+) ions tend to rush into the cell from the outside along with the electrochemical gradient, because these ions want to go from high concentration and positive membrane charge to where there is a lower concentration of Na+ and a more negative membrane charge. This action depolarizes the membrane, meaning the difference in voltage between the inside and the outside of the cell membrane becomes less negative. Depolarization of the cell membrane increases the likelihood of firing an action potential down that neuron, opening calcium (Ca2+) channels in the synaptic terminals, causing an influx of calcium, which causes vesicles filled with neurotransmitters to fuse to the presynaptic membrane, releasing the neurotransmitters into the synapse, starting the whole process over again.
What increases the amount of information a neuron can receive?
There are different types of receptors, which allow neurons to receive information. In nose you have chemoreceptors. In eyes you have photoreceptor. In the ears you have hair cells of different length, which resonates with sounds of different frequency. On the surface of the tongue you have again chemoreceptors. In the skin you have different types of receptors to give you information like heat, cold, pain, touch and vibration sense.
What happens when the impulses reaches the axon terminal?
Neurotransmitters are released and go into the synaptic cleft.
What is property of synapse?
Here are some definitions of the word synapse: 1. The association of homologous chromosomes with chiasma formation that is characteristic of the first meiotic prophase and is held to be the mechanism for genetic crossing-over. 2. The definition of a synapse is the junction between two neurons or nerve cells where there is a small gap that neurotransmitters help nerve impulses to cross. 3. In popular culture, "synapse" is often used to describe a thought in a most artistic form, or even a "jerk reaction" to a certain stimuli. It would seem that the term means a place where two things (or ideas) come together or a union is formed. The synapse in the nervous system is a very tiny space when information is carried by neurotransmitters to allow the information to continue on.

What happens to left over toys at mcdonalds?
Sells them on eBay.
How does the impulses get over the synapses?
Neurotransmitters. It's purely chemical.
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
Do axon and dendrite touch?
No they do not. Information (neurotransmitters) is electrically fired over to the next neuron.
What happens when Mallard eggs hatch and there are a couple left over that haven't?
they get eaten by other animals

What happens to half an orange over 2 weeks left out in the open?
it's definetily rotten or moldy!
What happens to salt water when it is left out over a period of time?
the water evaporates, leaving the salt behind.
