How is the message carried from one neuron to another if there is a space between them?
This gap is called a synaptic gap and a chemical called a neurotransmitter is used as a bridge over the gap.This message is carried via neurotransmitters. There are several types. Some speed up the transmission or slow it down or even stop it. They are like chemical bridges.
How do axon terminals maintain their synaptic position at dendrites?
Synaptic adhesion molecules span the synaptic cleft, holding the axon terminal to the dendrite. There are a number of different kinds of synaptic adhesion molecules, which typically have a portion that starts slightly inside an axon terminal and protrudes outside more than halfway into the synaptic cleft, meeting and over-lapping and sticking against a companion sam protruding similarly from a dendrite, thus maintaining the relative position of the axon terminal and dendrite.
Why is it that the electrical impulse cannot pass from neuron the muscle cell?
There is a space (synapsis) between the neuron and the muscle cell. The electrical impulse can not pass over that. Chemical neurotransmitters are manufactured by neurons in the soma, then stored in little bundles called synaptic vesicles and transferred to the synapses. The release of the neurotransmitter is required for a nerve to simulate the muscle. This is what crosses the space.
What occurs over a small area?
Weather occurs over a small area. Climate occurs over a whole region.
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 are the main differences between between a hormone response and synaptic transmission?
A hormone response is far-reaching and can affect more than one cell or tissue group and can last minutes to hours, even days. Synaptic transmission is strictly locally acting and is over and done with shortly after it begins (i.e, the neurotransmitters are quickly cleared to prevent ongoing stimulation).
What happens when the impulses reaches the axon terminal?
Neurotransmitters are released and go into the synaptic cleft.
How does the impulses get over the synapses?
Neurotransmitters. It's purely chemical.

Do axon and dendrite touch?
No they do not. Information (neurotransmitters) is electrically fired over to the next neuron.

Weather occurs over a small area. Climate occurs over a whole region.

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.

Which phase of meiosis occurs right after crossing over?
Before crossing over, interphase I takes place. Crossing over occurs during prophase I. Metaphase I occurs after prophase I.
