How does an impulse cross a synaptic gap between two nerve cells?
Neurotransmitters send the impulse across the synapse
An impulse reaches the CNS from the PNS via the?
Afferent nerves
What is the small gap between neurons called?
The small microscopic gabs b/w the two neurons are called "Synapse". The conduction of nerve impulse through this synapse is made possible through Neurotransmitters. As the impulse reaches at the Pre-synaptic membrane the small vesicles release these Neurotransmitters which initialize the impulse in post-synaptic membrane.
What happens in the synapses?
An action potential (or impulse, if you like) reaches the "presynaptic knob". This causes calcium gates in the membrane to open, and an there is an influx of calcium ions into the axon. this causes vesicles (like little sacks) containing transmitter substance, to move towards, and fuse with, the synaptic membrane. this causes the transmitter substance to diffuse across the membrane, where it combines with specfic receptor proteins on the post synaptic membrane. These cause an increased permeability in the membrane to sodium ions, and these rush in. if the threshold value was reached, the influx of NA+ ions will be sufficient to cause an action potential / impulse, and the impulse will travel down the axon.
Is a nerve message also called a synapse?
Nerve messages are called an impulse. Synapses are the space between two axons.
The greater the amount of coating the axon the faster the nerve impulse will be transmitted to the synapse?
myelin
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.
What is the location from which a nerve impulse is transmitted from one nerve cell to another?
synapse
Space through which a nervous impulse is transmitted from one neuron to another?
The space through which a nervous impulse is transmitted from one neuron to another is called a synapse. It is a tiny gap between the axon of one neuron and the dendrite of another, where neurotransmitters carry signals across the gap to continue the message.
What happens to the body when the receptors that remove catecholamines from a synapse have very low activity?
No impulse is transmitted. Hence the all or nothing principal.
How does the impulse jump the synapse?
Chemical diffusion
What is a synapse and how is information transmitted at the synapse?
A synapse is the gap between two neurones where messages can be sent.
A small space across which an impulse travels to move from one neuron to another?
It is most definitely a synapse.
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 carries an impulse across a synapse to a muscle?
neurons?
What happens at the synapse between two neuron?
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
