English - English
Any substance, such as acetylcholine or dopamine, responsible for sending nerve signals across a synapse between two neurons
n Substance that transmits nerve impulses between nerve cells
A complex molecule which acts as a chemical messenger for conveying electrical signals between neurons at synaptic points
a chemical, such as acetylcholine, which is released from the axon of one neuron and binds to a specific site in the dendrite of an adjacent neuron, thus triggering a nerve impulse; [*]
{i} inter-neural chemical conductor, chemical carrier of information throughout the nervous system (Neurology)
neurotransmitter, chemical that transmits information across the junction (synapse) that separates one nerve cell (neuron) from another nerve cell or a muscle Neurotransmitters are stored in the nerve cell’s bulbous end (axon) When an electrical impulse traveling along the nerve reaches the axon, the neurotransmitter is released and travels across the synapse, either prompting or inhibiting continued impulses There are more than 300 known neurotransmitters, including the ENDORPHINS and ACETYLCHOLINE 1
Chemicals that act as messengers between cells in the brain and nervous system; they transmit impulses across the gap from a neuron to another neuron, a muscle, or a gland
A chemical messenger produced in and released by one neuron A neurotransmitter can excite or inhibit another neuron
The chemical messenger released from a synaptic terminal to influence a postsynaptic target cell
Chemicals that transmit impulses between nerve cells or between nerve cells and effector cells
A chemical that is released during a nerve impulse that transmits information from one nerve cell to another
Chemical substance released at the terminals of axons across synapses that excite or inhibit target dendrites on neighboring neurons
Specialized chemical messenger (e g , acetylcholine, dopamine, norepinephrine, serotonin) produced and secreted by nerve cells that sends a message from one nerve cell to another Neurotransmitters play different roles throughout the body, many of which are not yet fully understood
= any endogenous compound that plays a role in synaptic nervous transmission
Chemical released by neurons to stimulate neighbouring neurons, allowing impulses to be passed from one cell to the next throughout the nervous system. A nerve impulse arriving at the axon terminal of one neuron stimulates release of a neurotransmitter, which crosses the microscopic gap (see synapse) in milliseconds to the adjoining neuron's dendrite. Many chemicals are believed to act as neurotransmitters. The few that have been identified include acetylcholine, dopamine, and serotonin. Some neurotransmitters activate neurons; others inhibit them. Some mind-altering drugs act by changing synaptic activity
A chemical in the brain which carries messages between the neurons
– A substance such as a hormone or protein that is found naturally in the body and that carries signals between nerve cells and other cells
a chemical messenger (e g , dopamine, serotonin) used to communicate among neurons and between neurons and other types of cells
Chemicals produced by neurons to carry their messages to other neurons
Neurotransmitter refers to a chemical that is required to transmit nerve impulses between nerve cells At least three classes of neurotransmitters respond to diet: 1 catecholamines (dopamine and norepinephrine) come from the amino acid, tyrosine Eating a protein-rich meal can increase tyrosine levels in the blood and the brain Elevated brain tyrosine increases dopamine and norepinephrine production, promoting wakefulness and alertness 2 Serotonin, which comes from the essential amino acid tryptophan, tends to induce relaxation and sleep Eating a meal high in carbohydrates is believed to increase brain tryptophan levels 3 Acetylcholine is manufactured from choline, a nitrogen-containing nutrient needed for neurotransmitter synthesis Back to Top
A chemical that carries signals across a synapse, from one neuron to another
transmits nerve impulses across a synapse
A substance secreted by excited nerve cells (neurons) that conveys the nerve signal to another nerve cell across the gap, or synapse, between the two cells
A chemical that is released from one neuron and attaches to an adjacent neuron triggerring a nerve impulse Back to Homepage O o
A chemical that is released from a nerve cell which thereby transmits an impulse from a nerve cell to another nerve, muscle, organ, or other tissue A neurotransmitter is a messenger of neurologic information from one cell to another
a chemical used by the nerves for communication
a chemical substance that relays impulses from one neuron to another
A chemical "messenger" within the body that carries a message from one nerve cell to another one A few of the more common ones are acetylcholine, dopamine, norepinephrine, and serotonin
A chemical that is released from a neurone and transmits a message to either a nerve or a cell Examples include dopamine and acetylcholine
