The point at which two neurones meet is called the synapse. At this point there are 2 situations:
1: there is no gap, the neurones are physically connected by gap-junctions. This is a rarer situation but does occur. In this case the nerve impulse continues down the second neurone (known as the post-synaptic nerve)
2: there is a small gap (a few micrometers) between the cells. In this case the first nerve, carrying the impulse, (pre-synaptic) causes a release of a chemical known as a neurotransmitter. There are various types of neurotransmitters and each are involved in different situations. When the neurotransmitter reaches the 2nd nerve it binds to the membrane (in most situations) which either causes the cell to depolarize and continue the impulse, or causes hypo-polarization which prevents any other nerve stimulating it.
Short and Simple Answer:
Nerve impulse is transmitted by:
- nerve impulse triggers transmitter substance
- which diffuses across synapse
- the transmitter substance binds with receptor molecule in membrane of next molecule
What else can I help you with?
What is the name of the region where two neurons are in done contact is known as?
synapse is that junction through which impulse can be transmitted from one neuron to another.
Where does a nerve impulse start?
A nerve impulse typically starts at the dendrites of a neuron, where it receives signals from other neurons or sensory receptors. These signals are then transmitted down the axon of the neuron to the axon terminals, where they can communicate with other neurons or target cells.
How nerve impulsive are transmitted from the receptor to central nervous system to effectors?
Nerve impulses are transmitted from the receptor to the central nervous system via sensory neurons. In the central nervous system, the impulse is processed and may be relayed to motor neurons that carry the impulse to effectors such as muscles or glands to produce a response. This pathway allows for communication and coordination between different parts of the body.
Functional connection between two neurons is a?
functional connection between two neurons is the transmission of electrical signals from one neuron to another through a synapse. When an electrical impulse reaches the axon terminal of the pre-synaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the post-synaptic neuron, allowing the electrical signal to be transmitted and continue the communication between neurons.
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.
What transmits impulse between sensory and motor neurons?
Nerve impulses are transmitted between neurons via neurotransmittors that are released into the synapse by the sending neuron. The neurotransmittor then binds to a receptor on the receiving neuron; when enough receptors are triggered, an action potential is initiated on the receiving neuron.
What type of nervous tissue that conducts a nerve impulse?
Neurons
What generate and transmit nerve impulse?
A sensory stimulus can generate a neural impulse, as can repeated or multiple inputs of neural signals from other neurons.A neural signal is transmitted from one neuron to anotheracross a synapse via chemicals called neurotransmitters, and a neural impulse is transmitted along an axon of a neuron by either an action potential (in an unmyelinated axon) or by saltatory conduction (in a myelinated axon).
What is a message that travels through a neurons?
An Impulse
Transmission of an impulse between neurons depends primarily on?
The transmission between neurons depends on the number of neurotransmitters that are present. If there aren't enough transmitters, the impulse is not passed into the second neuron, meaning it's cut down. If there are enough, it leads to an action potential (nerve impulse) in the second neuron. The nerve system is a rather confusing, and very technical, system in the body.
What is stimuli impulse?
A stimulus is any event that evokes a specific response in an organism, while an impulse is a message carried by neurons in response to a stimulus. When a stimulus is detected by sensory receptors, it triggers an impulse that is transmitted through the nervous system to elicit a reaction or behavior.
What carries an impulse across a synapse to a muscle?
neurons?
