Neurotransmitters don't relay messages. They are chemicals released from one neuron that diffuse across the synaptic cleft and bind to postsynaptic receptors on another cell. 'Messages' is a simile that people use to anthropomorphise how neurons work but actually - any message as such, which you might call a thought, is an enormously complex abstraction of millions of these events happening in a close temporal sequence.

∙ 12y agoThe signal from one neurone is passed to the next are a gap between the two called the synapse. The presynaptic neurone (the sender) has an AP the comes down the the end of the axon where it stimulates, through various mechanisms, the release of something called a neurotransmitter. The neurotransmitter difuses across the gap the the postsynaptic cell (the receiver) where is activates binding proteins which change the concentration OS ions within the cell (usually be opening ion channels) so depolarise the membrane. If the depolarisation is sufficient then another action potential in the postsynaptic cell will be initiated.

What message moves from one end of a neuron to another in the form of what?
resting potential
What molecule is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from a neuron to an effector cell?
Neurotransmitter
A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from a neuron to an effector cell?
Neurotransmitter.
The space between one neuron and the next is a?
This area is referred to as the synaptic cleft. This area is bound by the end of one neuron (the terminal bouton) and the post-synaptic membrane of the next neuron. When an action potential reaches the terminal bouton, Ca2+ influx triggers the release of neurotransmitters across the cleft, which bind to receptors on the post-synaptic membrane, allowing for an post-synaptic excitatory potential (PSEP) to be formed in the next neuron.
What is the major function of neuron in nervous system?
i think the activitity of neoron is to pass the the information from one neuron to another neuron throuh electric signals and lastly it changes in to chemical when it reaches to the another neuron.
How does a message travel from one neuron to the next?
It travels from the brain to the Spinal Cord.
How is a nerve specialised to carry out its function?
A nerve cell is called a neuron. The neuron has dendrites that receive impules from the previous neuron and send it to the cell body and an axon that transmits the impulse to the next neuron. There is a space between one cell's axon and the next cell's dendrites called a synapse. Neurotransmitters are released from the axon terminal to carry the impulse across the synapse.
What effect do neurotransmitter from one neuron have on the next neuron?
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
What type of neuron carries a message from one neuron to another?
It is called an Interneuron
What effects do neurotransmitters from the neuron have on the next neuron?
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
What is the space between two neurons called?
The space between the ending of one neuron and the communication with the next neuron is called the synapse, or sometimes it is called the synaptic gap or synaptic cleft. But synapse is the common term.
Does myelin sheath transmits impulses from one nuron to another?
Myelin sheath never transmits the impulse from one neuron to another. On the contrary these are insulating cells which prevent transmission of nerve impulses.
How is the message caried from one neuron to another it there is a space between them?
The synaptic gap is the space between the dendrites of one neuron and the axon of the next. The impulse is carried across this space by chemicals called neurotransmitters which conduct the electrical impulse.
Which part of the neuron transmits information to other cells?
The end of one neuron, the presynaptic button, sends messages to other cells by releasing neurotransmitters (chemical messengers) into the synaptic cleft (a small space between two neurons). The other cell, whether it be a neuron, a muscle, a sweat gland, etc., will receive this message at the post synaptic membrane of its cell, and will respond accordingly.
Do neurons touch?
No. There is a synaptic cleft between the axon of one neuron and the dendrite of another neuron. At the synapse, a chemical messenger is needed - in order to carry the "message" from one nerve to the next, whereupon electrical transmission once again occurs (via depolarization and then repolarization).
What is the location of the vesicles that store neurotransmitter?
Synapses are located throughout the nervous system. A synapse is a sort of 'relay station' where a message, in the form a a chemical neurotransmitter, is passed on between one neuron (nerve fibre) & the next, or between a neuron & the muscle or gland the message is aimed at.
What A message moves from one end of a neuron to another in the form of what?
resting potential
