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.

When a nerve impulse reaches the nerve endings, neurotransmitters such as acetylcholine, dopamine, serotonin, or norepinephrine are released into the synapse to transmit the signal to the next neuron or target cell. These neurotransmitters bind to receptors on the receiving cell, initiating a response.

Neurotransmitters 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

In a neuron impulses move?

In a neuron, impulses move through electrical signals known as action potentials. These action potentials are generated when a neuron receives enough stimulation to reach a threshold, causing a rapid change in membrane potential. The action potential then travels down the length of the neuron's axon until it reaches the next neuron or target cell.


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?

Chemical synapses release neurotransmitters when a neural impulse reaches the end of an axon to transmit information to the next neuron. This release of neurotransmitters allows for communication between neurons and helps propagate the neural impulse across the synaptic gap to continue the signal.


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).


Is it correct that synaptic clefts prevents an impulse from being transmitted directly from one neuron to another?

Yes, that is correct. The synaptic cleft is a small gap between neurons, and it prevents direct transmission of impulses. When an impulse reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the adjacent neuron, allowing the impulse to be transmitted indirectly.

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 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 chemical is released into the gap?

neurotransmitter


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.

What happens when an impulse reaches the synapse?

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.

Is fire an example of potential energy?

No, fire is an example of chemical energy, not potential energy. Potential energy is stored energy due to an object's position or state, while chemical energy is stored within the bonds of chemical compounds and is released during a chemical reaction.
