What Chemical reaction causes the electrical impulse in a neuron to start?
The chemical stimuli in the body are converted into electrical impulses when some sensory input system in the body is triggered. This can be a visual sense like the eyes, or a aural sense like the ears. The chemical stimuli gets converted into potential energy and converted.
Parts of a multipolar neuron its order of receiving nerve impulses?
The parts of a multipolar neuron include the dendrites which receive nerve impulses, the cell body which integrates the signals, and the axon which conducts the signals away from the cell body. In terms of receiving nerve impulses, the order is generally dendrites, cell body, and then axon.
What happens at the synapse between two neuron?
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
What transmits impulse between sensory and motor neurons?
Nerve impulses are transmitted between neurons via neurotransmittors that are released into the synapse by the sending neuron. The neurotransmittor then binds to a receptor on the receiving neuron; when enough receptors are triggered, an action potential is initiated on the receiving neuron.
What are the sources of stimulation that start a nerve impulse?
Sources of stimulation that can start a nerve impulse include chemical signals (neurotransmitters released at synapses), physical stimuli (such as pressure or temperature changes acting on sensory receptors), and electrical signals (generated by neighboring neurons or external electrical sources). These stimulations can trigger the opening of ion channels in the neuron's membrane, leading to changes in membrane potential and initiation of an action potential.

Describe the location and action of a pacemaker?
Pacemaker is located in the right atrium and generates electrical impulses to start a muscle contraction in the heart.

Where is the neuron in the body?
Neuron is the nerve cells that carry messages to the brain .The various parts of neuron are dendrite ,axon ,nucleus , cell body and nerve ending . All the information from the environment is detected by the specialised tips of nerve cells .These receptors are usually located in our sense organs such as,nose , tongue and so on. The information acquired at the end of the dendritic tip of a nerve cell sets off a chemical reaction that creates an electrical impulse . This impulse travels from the dendrite to the cell body , and then along the axon ,to its end .At the end of the axon , the electrical impulse sets of the release of some chemicals . These chemicals cross the gap or synapse, and start a similar electrical impulse in a dendrite of the next neuron . This is how nerve impulse travel in a body
How did cancer research start?
with a neuron with too much time on its hands
How do impulses travel throughout the nervous system?
An impulse travels from one nerve to another by release & subsequent diffusion of chemicals called neurotransmitters across a very small gap between neurons, called a synapse.How neurotransmitters are released: As an impulse reaches an end of a neuron (the axon terminal), the impulse opens ion pores in that axon terminal which allows Calcium ions to enter, which cause the movement of small membrane bounded packets of neurotransmitter chemicals, called vesicles (like tiny water balloons), to move to the cell membrane, where the vesicles fuse into the cell membrane, thus releasing the contents, the neurotransmitters, into the small space (the synaptic cleft) between the axon terminal and the dendrite of the post-synaptic neuron (the neuron the impulse is traveling to).What neurotransmitters do when they reach the post-synaptic neuron: The post-synaptic neuron has many receptor structures each of which are like a combination of a "well", and an open-and-closeable tunnel or pore. The "well" (or hole with a bottom surface) is a RECEPTOR for the neurotransmitter chemical, in that the neurotransmitter FITS into that well like a key into a lock. And when a neurotransmitter diffuses to and enters that well, it affects the shape of the companion tunnel (ION PORE), such that the ion pore OPENS, thus allowing Sodium ions to enter the post-synaptic neuron (normally at a dendrite, the manifold tiny input structures for a neuron).A previous answer slightly improved: Nerve impulse travelingThe impulse is like an electrical current which 'flows' along the nerves cells, their inputs ('branches' called dendrites), their outputs (axons), and the junctions between nerves; but it is not so simple as a regular electrical wire, because a complex biochemical process is also involved. This process is responsible for the initial creation of the electrical current, to its re-creation some additional times along its passing (- otherwise it would have died out because of the long lengths such an impulse travels), and to its re-creation in any 'new' nerve cell it reaches.
What is the difference between ascending and descending impulses?
Ascending impulses refer to nerve signals traveling towards the brain, carrying sensory information from the body. Descending impulses, on the other hand, refer to nerve signals traveling from the brain down the spinal cord to control motor functions and movement in the body.
How do you get the neuron on saints row 3 without going back to the start?
thier everywhere you get one right at the beging of the game when you start free roam.
The start of an action potential?
The action potential begins when the neuron is stimulated and reaches a certain threshold of excitation. This causes voltage-gated ion channels to open, allowing a rapid influx of sodium ions into the neuron, leading to depolarization. This depolarization triggers a cascading effect along the neuron's membrane, resulting in the propagation of the action potential.
