Which part of the neuron is capable of generating an action potiental?
The axon hillock is the part of the neuron that is capable of generating an action potential. It integrates incoming signals from the dendrites and, if the threshold is reached, triggers the action potential to be propagated down the axon.
When a neuron's resting potential is occurring the neuron is what charge on the inside?
resting potiental
What do resting and action potentials depend on?
The resting and action potentials depend on the balance of charges of the area outside the neuron and inside the neuron. A resting potential is when the neuron is more negatively (approximately -70mv) charged than the area outside the neuron. The action potential occurs when sodium ions rush into the neuron, causing the polarity to be reversed. When there is no difference in charge between the area inside the neuron and the area outside the neuron, no action potentials can be started by that neuron.
What happen to neurotransmitter after an action potential?
After an action potential reaches the presynaptic terminal of a neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters bind to receptors on the postsynaptic neuron, possibly generating a new action potential. Subsequently, neurotransmitters are typically removed from the synaptic cleft through reuptake into the presynaptic neuron, enzymatic degradation, or diffusion away from the synapse to terminate the signal. This process ensures proper communication between neurons and prevents excessive stimulation.

Which condition is a neuron in when the outside of the neuron has a net positive charge and the inside has a negative charge?
resting potiental
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 messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire?
Inhibitory messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire. These messages typically involve neurotransmitters such as GABA or glycine, which hyperpolarize the neuron's membrane potential, making it less likely to reach the threshold for firing an action potential.

Why are motor neuron ofter referred to as the action cell?
it is often termed the action neuron because it tells the muscles what to do or how to react.
Which neurons decide about the action for a certain stimulus?
Sensory neuron
How do action potentials move from one neuron to another?
The action potential stimulates the axon terminal to release its neurotransmitters. The neurotransmitters attach themselves to the dendrote of the next neuron, so that it will open its NA+ channels.
