How are synapses adapted for diffusion?
The synapse releases a chemical that can diffuse across the gap between two neurones. The synapse has a large surface area, which means diffusion of the chemical can occur at a higher rate.
What helps carry nerve impluses across the synapse?
Neurotransmitters encased in vesicles and diffusing across the synaptic gap.
What is the name of the tiny gap the neurotransmitter has to diffuse across to reach the membrane of the postsynaptic neuron?
the synapse
Neural transmission across a mammalian synaptic gap is accomplished by?
impulses causing the release of a chemical signal and its diffusion across the synapse.
Does ionic current exist in chemical synapse?
not within the synaptic CLEFT (gap) itself, across which neurotransmitters diffuse, but yes, in the axon & axon terminal leading up to the synapse, and in the dendrite coming from the synapse.
What is sentence with the synapse?
A synapse is the gap between a neuron.
How does an impulse cross a synaptic gap between two nerve cells?
Neurotransmitters send the impulse across the synapse
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.
What is A small space across which an impulse travels to move from one neuron to another?
Synapse. The gap itself is called the synapticcleft.
What is the space between 2 neurons where electrical and chemical signals jump from neuron neuron?
It's a 'bridge' where the neurotransmitters jump from one neuron to the other. It is called synapse. This is a simple notion that I have about this subject. For a complete review involving this part of the brain and how it works see the link to "Neuron" below.
What is the junction point between neurons?
A synapse is the junction or a point of close contact between two neurons.
How is transmission across the synapse halted?
There are three ways to end chemical signaling across a synapse. In some cases, the neurotransmitter molecules simply diffuse away from the synapse. In others, enzymes located in the synaptic gap deactivate the neurotransmitters. Finally, neurotransmitters are taken up by the releasing neuron in a process known as reuptake.
