How does a message travel through a single neuron?
When a message gets sent to a neuron from the dendrite it goes through the cell body to the tip of the dendrite where it leaps to the next dendrite.
How does a message travel from one neuron to the next?
It travels from the brain to the Spinal Cord.
What part of the neuron carry the message from the brain to muscles of your hands and backbone?
Messages from the neuron always travel from the cell body down the axon.
In what order does a message travel through the neuron?
A message travels through a neuron in the following order: dendrites receive the signal, the signal is passed through the cell body (soma), travels down the axon, and finally reaches the synaptic terminals where it is transmitted to the next neuron.
Why do action potentials travel in one direction?
Action potentials travel in one direction because of the refractory period, which prevents the neuron from firing again immediately after an action potential has been generated. This ensures that the signal moves in a linear fashion along the neuron.
What happens when neurotransmitters communicate an excitatory message to the postsynaptic neuron?
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
Define relay neuron?
a relay neuron is the neuron that picks up the message from the sensory neuron and delivers it to the motor neuron in the spinal cord or the brain
The part of the neuron that decided if the message will travel to the next neuron or not is the what?
The axon terminal is the part of the nerve responsible for sending the message at all. Not only does it send the message, though, it has branching paths which allow it to determine which path it'll go on.
Why does the action potential travel in one direction?
The action potential travels in one direction because of the refractory period, which prevents the neuron from firing again immediately after an action potential has been generated. This ensures that the signal moves in a linear fashion along the neuron.
What type of neuron carries a message from one neuron to another?
It is called an Interneuron
What bridge the gap between a neuron sending a message and the neuron receiving it?
neurotransmitters
Why is it helpful to have impulses move only in one direction in a neuron-?
Nerve impulses travel one direction because of the action potential which is created because of Na+ and when K+ returns to normal.
