SYNAPSE: Axon terminal synapse. The space between the junction of two neurons in a neural pathway, where the termination of the axon of one neuron comes into close proximity with the cell body or dendrites of another.
What is the difference between a neurotransmitter and a synapse?
Neurotransmitters may excite the neuron they bind to or inhibit it. Think of the nerve signal like the electrical current, and the neurons like wires. Synapses would be the outlets or junction boxes that connect the current to a lamp (or other electrical appliance of your choosing), allowing the lamp to light.

What is synapse Brainly?
Answer: synapse is the gap between two adjacent neurones. here electrical impulses are converted into chemicals by which message convey from axon terminal to dendrites.
What is synapse Shala?
Solution. Synapse is a place or a gap where two adjoining dendrites or axons meet but never unite, as there is no continuity between the nerve cells. At the synapse, acetylcholine is secreted which prevents back flow of the impulse. Concept: Human Nervous System.
What is a synapse Class 12?
Note:Synapse is a junction between two neurons which passes information from one neuron to the next. Neurons are not continuous throughout the body, they still communicate with each other in a manner known as the neuron doctrine.
What is synapse and its type?
A synapse is the contact site where a neurone and another neurone or a neurone and another cell meet. The presynaptic neurone/cell is the transmitting cell; the postsynaptic neurone/cell is the receiving cell. There are two major types of synapse - electrical and chemical.
What is chemical synapse?
Chemical synapses are connections between two neurons or between a neuron and a non-neuronal cell (muscle cell, glandular cell, sensory cell). The synaptic complex is the non-reducible basic unit of each chemical synapse as it represents the minimal requirement for an efficient chemical synaptic transmission.
What is a synapse Class 10?
Synapse is the gap between nerve ending of one neuron and dendrites of another. At synapse, the electrical impulse generated at dendrites of a neuron is passed on to dendrite of another neuron in the form of chemicals by on ending of the first neuron.
What is synapse function?
In the central nervous system, a synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells. Synapses are key to the brain's function, especially when it comes to memory.
What are the 3 types of synapses?
We found three types: I = communicating axosomatic synapses; II = communicating axodendritic synapses, and III = communicating axoaxonic synapses'. When three neurons intervene in the synaptic contact, they could be termed 'complex communicating synapses'.
What is synapse and its types?
A synapse is the contact site where a neurone and another neurone or a neurone and another cell meet. The presynaptic neurone/cell is the transmitting cell; the postsynaptic neurone/cell is the receiving cell. There are two major types of synapse - electrical and chemical.

How do electrical synapses work?
In electrical synapses, two neurons are connected by specialized channels known as gap junctions. Electrical synapses allow electrical signals to travel quickly from the presynaptic cell to the postsynaptic cell, rapidly speeding up the transfer of signals.
What are the parts of a synapse?
Synapses are composed of three main parts: 1 The presynaptic ending that contains neurotransmitters 2 The synaptic cleft between the two nerve cells 3 The postsynaptic ending that contains receptor sites
What happens when a neuron reaches the end of the neuron?
Instead, it must trigger the release of neurotransmitters which can then carry the impulse across the synapse to the next neuron.
How big is the gap between electrical and chemical synapses?
The gap between electrical synapses is much smaller than that of a chemical synapse (about 3.5 nanometers compared to 20 nanometers).
Which end of the neuron contains receptor sites?
The postsynaptic ending that contains receptor sites. An electrical impulse travels down the axon of a neuron and then triggers the release of tiny vesicles containing neurotransmitters. These vesicles will then bind to the membrane of the presynaptic cell, releasing the neurotransmitters into the synapse.
What is the function of the synapse?
The synapse subserves the transmission of nerve impulses, commonly from a variably large (1-12 mcm), generally knob-shaped or club-shaped axon terminal (the presynaptic element) to the circumscript patch of the receiving cell's plasma membrane (the postsynaptic element) on which the synapse occurs. In most cases, the impulse is transmitted by means ...
What is the synapse of a neuron?
synapsis, point of contact] SYNAPSE: Axon terminal synapse. The space between the junction of two neurons in a neural pathway, where the termination of the axon of one neuron comes into close proximity with the cell body or dendrites of another .
What is the name of the synapse in which electrical impulses are transmitted via ionic currents?
There is another type of synapse called an electrotonic synapse (electric al synapse) in which electrical impulses are transmitted via ionic currents from one neuron to another by direct propagation across a gap junction (2-3nm wide).
What happens when a nerve cell contacts another nerve cell?
the point at which one nerve cell connects with another and at which transmission of an impulse takes place by chemical means. When an impulse arrives at a synapse it causes a synaptic vesicle to move towards the presynaptic membrane. On contacting the membrane it discharges the contained transmitter substance into the synaptic cleft, across which it diffuses to the postsynaptic membrane which it depolarizes. This causes a positive charge to develop (excitory postsynaptic potential -EPSP) because of sodium ions flowing into the post synaptic nerve cell. When the positive charge builds up sufficiently it generates an action potential which is usually unidirectional. See ENDPLATE, MOTORand Fig. 148 .
What is the point at which one nerve cell connects with another and at which transmission of an impulse takes place by chemical?
synapse . the point at which one nerve cell connects with another and at which transmission of an impulse takes place by chemical means. When an impulse arrives at a synapse it causes a synaptic vesicle to move towards the presynaptic membrane.
What is the role of neurotransmitter molecules in the synapse?
The neurotransmitter molecules diffuse across the synaptic cleft, bind with specific receptors on the postsynaptic membrane, causing depolarization or hyperpolarization of the postsynaptic cell. See also neuron. Components of a synapse. From Applegate, 2000.
Which part of the cell transmits nerve impulses?
The synapse subserves the transmission of nerve impulses, commonly from a club-shaped axon terminal (the presynaptic element) to the circumscript patch of the plasma membrane of the receiving cell (the postsynaptic element) on which the synapse occurs.
