A neuron fires only when its membrane reaches what?

A neuron fires when its membrane reaches a certain threshold potential. This threshold potential is typically around -55 to -65 millivolts. When the membrane potential reaches this level, an action potential is triggered and the neuron fires.


A neuron starts to fire an impulse by the influx of what ions?

A neuron fires an impulse by the influx of sodium ions into the cell. This creates a temporary change in the neuron's membrane potential, leading to depolarization and the generation of an action potential.


The message that travels through a neuron?

The message that travels through a neuron is an electrical impulse called an action potential. It is generated when the neuron is stimulated and travels along the neuron's axon, facilitated by the movement of charged ions. This ultimately allows the neuron to communicate with other neurons or target cells.


Where neuron cell bodies located?

The cell body, called the SOMA, is the main part of the neuron. It is the main metabolic center or region of the neuron. The neuron has 3 parts: DENDRITES (inputs), SOMA (cell body), and AXON (output). The axon is the part which FIRES when sufficient inputs reach it at the axon hillock.


Why causes the neurons fire?

Neurons are nerve cells, and they fire to relay messages from neuron to neuron. Neurons fire when a charge jumps across a synapse to the dendrite of a cell. The neuron then fires the charge down it's axon, and the charge travels to the next neuron.

When a neuron is depolarized to threshold?

1. The neuron fires an action potential, sending the electrical signal down the axon.


What cause neuron to fire?

The neuron adds up all the excitatory and inhibitory inputs and fires when they reach its threshold of excitation.

What neuron is before a synapse?

The synapse consists of the two neurons, one of which is sending information to the other. The sending neuron is known as the pre-synaptic neuron (i.e. before the synapse) while the receiving neuron is known as the post-synaptic neuron (i.e. after the synapse).


When neuron stimulated enough it?

When a neuron is stimulated enough, it reaches its threshold potential and fires an action potential. This action potential travels down the axon of the neuron, allowing for the communication of signals to other neurons or cells.

What was Excitation and Inhibition about?

Excitation and Inhibition occur in the neurons. Excitation is when a neuron becomes depolarized and fires an action potential. Inhibition is when a neuron becomes hyperpolarized preventing it from firing an action potential.
