Synapse: neurotransmitters from the pre-synaptic membrane spill into the synaptic cleft (synaptic gap), where the electrical impulse is transferred to the dendrites of the post-synaptic membrane.

There are chemical synapses, and electrical synapses; chemical synapses involve neurotransmitters diffusing across a small space between the neurons, and electrical synapses involve a much smaller gap called a gap-junction, where ions move through channels resulting in an electrical current.
Electrical signals move down an axon but are not transmitted directly unless it is through a gap-junction. Chemical signals diffuse across a synapse and ultimately induce another electrical signal in the post-synaptic neuron.

∙ 13y agoThis area is called the synapse or synaptic cleft. Neurotransmitters from the presynaptic membrane (tip of the axon of the neuron "sending" the signal) are released via exocytosis from the neuron. The second neuron then receives the NTs on the postsynaptic cleft where ligand (chemical) gated channels, mechanically gated channels, and electrically gated channels allow for the influx of the NTs into the dendrite of the neuron receiving the signal.

What functions as a neurotransmitter?
When impulses reach a synapse they trigger the release of chemicals called neurotransmitters. Molecules of the neurotransmitter cross the synapse and stimulate the receiving neuron to fire an impulse of its own as wave like movements of ions. They may also actively inhibit a receiving neuron from firing.
What happens at a synapses?
The transfers that happens in the synapses conduct biochemical information from the neuron cells. The synapse, or synaptic cleft is the gap between to neuron cells. Nerotransmitters are chemicals that are released from one neuron (known as the pre-synaptic) and bond to receptors on the receiving neuron (known as the post-synaptic). The transfers that happens in the synapses conduct biochemical information from the neuron cells.
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.
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 role does neurotransmitters play in neurotransmission?
In between 2 neurones is the synaptic cleft, the gap between the pre and post-synapse. NTs are the molecules which activate receptors on the post-synapse during synaptic transmission, The activated receptors initiate intracellular mechanisms such as ion channel opening, G-protein activation, etc, which can inhibit or produce action potentials (nerve impulses).
What molecules send signals from one neuron to the next?
really how wud i know if i asked eddu!!
What part of the brain has branching fingers that receive signals?
The neuron has dendrites that receive signals from other cells and axons that bring the signal to the next cell.
What functions as a neurotransmitter?

Molecules of the neurotransmitter cross the synapse and stimulate the receiving neuron to fire an impulse of its own as wave like movements of ions. They may also actively inhibit a receiving neuron from firing.
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 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.
Describe parts of the neuron?
DENDRITE, SOMA, and AXON are the main parts of a neuron. Neurons signal one another via chemicals called NEUROTRANSMITTERS released at SYNAPSES. DENDRITES are usually the RECEIVING part, SOMA is the body of the neuron where the DNA is and most of the metabolic activity occurs, and AXON is the OUTPUT portion of the neuron. There can be many many DENDRITES, depending on the type of neuron, and the AXON can divide near its end and have some number of AXON TERMINALS. Neurons 'connect' at SYNAPSES (without exactly 'touching', that is without merging their cell membranes and sharing cytoplasm , and are held in place by SYNAPTIC ADHESION MOLECULES which protrude from each side of the synapse and stick to one another, binding the parts of the synapse together). A SYNAPSE is a tiny GAP between neuron structures (typically an AXON of one neuron and a DENDRITE of another), where the neural signal is conveyed from one neuron to the next via chemicals called NEUROTRANSMITTERS. A neuron signals another neuron in this way: as a neuron FIRES, an ACTION POTENTIAL is caused to move along the axon; when it reaches an AXON TERMINAL it causes tiny bags called VESICLES to merge with the cell membrane and release NEUROTRANSMITTERS into the SYNAPTIC gap (or CLEFT) between the neurons, where the neurotransmitters diffuse quickly to the post-synaptic DENDRITE. The dendrite has LIGAND-GATED ION PORES which have structures which receive the neurotransmitters, like a key into a lock, which then causes the pores to open and allow sodium ions into the dendrite. These sodium ions can then BEGIN this same process in that next neuron, if ENOUGH signals are received to TRIGGER its firing. A neuron can be TRIGGERED to FIRE if either MANY dendrites receive signals (called SPATIAL triggering), or if one or more dendrites receive many signals in quick succession (called TEMPORAL triggering).
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.
How is the communication between neurons an electrochemical event?
Because the charge travels from the dendrites to the axon to the head of the neuron, now remember neurons do not touch (synapse) so the the charge must now get to the dendrites of the next neuron from the head of the first, so the head releases chemicals called Nero transmitters that carry the impulse to the next neuron. thus Electro-Chemical

Which is the last part of the neuron to be involved in the transmission of a neural impulse towards the next neuron?
Signalling ALONG a neuron is electrical, but signalling BETWEEN neurons is a chemical process. Neuron A 'passes' a message onto the next by releasing chemicals called neurotransmitters , which are then taken up by neuron B. The point at which these neurotransmitters are released from the neuron A is called the 'terminal bouton' and is the end of its axon. More specifically, it is the presynaptic membrane OF the terminal bouton at which the passing on of a message occurs.
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.
Functions of synapse?
unidirectional transmissionSignals pass from presynaptic to postsynaptic neurone since: synaptic vesicles are only found in presynaptic neurone and receptors for neurotransmitter are only found in postsynaptic neurone.intterconnection between nerve pathwaysOne neurone may receive signal from many synapses from different presnaptic neurones. This allows a wide range of actions in response to a stimulus.memory and learningNeurones involved are linked by new synapses.
