What else can I help you with?
What are neurontransmitters?
a chemical that transmits a nervous systems signal across a synapse.
What is the space that impulses jump across by means of a transmitting chemical?
synapse
How do impulses cross synapse between neurons?
By a chemical released by an axon.
What does a neuron transmits signals from its what?
A neuron transmits signals from its cell body, where the nucleus is located, to other neurons or target cells through its axon. The axon carries the electrical impulses away from the cell body towards the synapse, where communication with other cells occurs.
Where does a neuron transmits it signals?
synapse
What is the area between neurons across which nerve impulses travel?
no, synapse. node of ranvier is between axon and dendrites
When nerve impulses from several presynaptic neurons stimulate a single postsynaptic neuron at the same time it is called?
chemical 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.
How does a synapse forward impulses?
a tiny electro-chemical charge passes from nerve endings called axons to nerve endings called dendrites
Can impulses pass in 2 directions across a synapse?
no
Which one of the following phrases describes the transmission of impulses to and from nerve cells?
There is a connection between two brain cells, called a synapse. When it reaches the end of one cell, the electric impulse transforms itself into a chemical substance, and is transferred from one cell to another. When it reaches the second cell, it is again transformed intro an electric impulse.
What is the small space between neurons where impulses pass?
Synapse
