What chemical is released when the nerve impulses reaches the nerve endings?

∙ 10y ago
Acetylcholine is NOT the only chemical transmitter released by nerve endings. There are literally dozens. Ach is only the first discovered. Others include: glutamate, aspartate, serine, gamma-aminobutyric acid, glycine,dopamine, norepinephrine, epinephrine (adrenaline), histamine, serotonin, melatonin, adenosine, anandamide,
True ACh was discovered first and is not the only neurotransmitter released, BUT Acetylcholine is basically the one of most important in producing an impulse.

∙ 10y agoNeurotransmitters are released (via exocytosis of neurotransmitter-containing vesicles) into the synapse when the action potential reaches the end of the axon. There are many different types of neurotransmitters, such as:
- acetylcholine
- glycine
- dopamine
- norepinephrine
- serotonin
- glutamic acid
- aspartic acid
- enkephalins
- endorphins

Which process stops when a ribosome reaches a stop codon?
When a ribsome reaches a stop codon, the translation process stops and a protein is released.
Why is the chemical synapses be release when a neural impulse reaches the end of an axon?
Neurotransmitters are released in order to transmit the message from the axon terminal to the other neuron by having said synapse "jump" to the neighboring dendrite.
What are two chemical reactions for which a galvanic cell may go dead?
Cell Reaches equilibrium
When a farmer sprays chemical spray on to crop plants how does the chemical travel to the roots of the plants?
The sprayed chemical is absorbed by the leaves, it reaches in the conducting tissues (mostly phloem) and travels to the root along with other supplies of that plant.
When the action potential gets to the end of the axon?
When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).
How is noradrenaline and acetylcholine involved in the regulation of the heart?
Noradrenaline is released when the medulla oblongata sends impulses along the nervous system and when the chemical reaches the S.A node (pacemaker), the noradrenaline makes the node fire more rapidly. Acetylcholine reaches the S.A node, and slows down the firing of the S.A node.
What chemical is released into the gap?
neurotransmitter
What is the function of a nerve ending?
At the end of a nerve, there is a synapse, which transfers the signal on to the next nerve until it reaches it's destination - ie. the brain or a muscle. Nerve endings are what we feel the world around us with. Nerve endings are in every part of your body and they are always sensing what is going on around you. They feel the chair against your bottom, the key board under your finger tips, etc.
What bodily function reaches the breakneck speed of 200 miles an hour?
Nerve impulses carried in myelinated axons.
What happens when the impulses reaches the axon terminal?
Neurotransmitters are released and go into the synaptic cleft.
What happens when an impulse reaches the synapse?
When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).
Which one of the following phrases describes the transmission of impulses to and from nerve cells?
There is a connection between two brain cells, called a synapse. When it reaches the end of one cell, the electric impulse transforms itself into a chemical substance, and is transferred from one cell to another. When it reaches the second cell, it is again transformed intro an electric impulse.
How do people see?
First, light passes through the transparent cornea. It then reaches the pupil. This expands or contracts depending on the amount of light that enters the eye. The iris controls the size of the pupil, to regulate how much light reaches the lens. The lens bends light rays and focuses them on the back of the eye, or the retina. The retina, then, changes light into nerve impulses through a complex process. These impulses are transmitted along the optic nerve to the brain, which interprets the impulses as images.
How nerve impulses travel?
each nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.a nerve impulse travels along the neuron in the form of electrical and chemical signals.Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contractionDownload the complete and 100% correct answer from following web linkhttp://tinyurl.com/stepuponstepEnjoy
