What happens when potassium (K ) leaves the neuron?
As potassium leaves the neuron, the inside of the cell will become progressively more negative, which will attract the positive potassium ions, preventing further exodus. If this electrical force is great enough, it will actually draw potassium ions from the outside of the cell back inside.
What happens if one of your leg motor neuron stop functioning?
The leg wouldn't be able to receive or transmit impulses and information from the central nerves system CNS to the muscle and glands
What is the path of an electrical impulse as it moves through a neuron?
The electrical impulse travels into the dendrites, the "input" of the neuron, and into the soma or "body" where the signal gets processed. From there, the processed signal travels down the axon or "output" and into the dendrites of another neuron.
What is a message that travels through the neuron?
An Impulse
How many times can a neuron fire per second?
Depends on the function of the neuron, the range goes from once per sec to 1000 pulses per sec.

What a neuron in your finger senses the temperature when you touch something hot?
The nerve cells that detect heat (located within your Dermis) activate when touching a hot surface. This nerve impulse then travels through your central nervous system to your brain when it is translated as "pain" or "damage" to the area. The signal travels back down the arm as a reaction to move the stimulous and causes you to move your hand.
When you touch something hot a neuron in your fingers senses the temperature which best decscribes the first reaction the neuron has?
Ions flow into the neuron. An action potential forms moves along the neuron. A response occurs, here, an aversion response... your body pulls your hand and finger away.
What happens when neurotransmitters communicate an excitatory message to the postsynaptic neuron?
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
How electrical activity of neurons might be measured?
The information each neuron processes determines how strong the action potential (electrical current) is within each neuron. An example of studying the electrical activity is by using temperature. The neurons which detect the temperature change are called sensory neurons. If you stimulate the neurons by leaving your fingertip in cold water for an adequate amount of time the electrical current within each neuron is increased as the temperature of your fingertip drops. The neurons within the fingertip sense the temperature drop and emit the electrical current, then the next neuron senses the temperature drop as the fingertip is held in the cold water and emits a stronger electrical current, the colder temperature in the next neuron as your finger is held in the water emits an even higher frequency and so on until the message arrives at the spinal cord and is then sent to the brain through the now very strong electrical current within the neurons informing it of the temperature decrease and then resulting in action outcome.
What is the Neuron function?
The function of a neuron is to transfer messages throughout the brain. These neurons are all attached and interpret everything that happens.
What happens when a substance gets into a neuron?
The substance tricks the neuron into releasing a flood of dopamine back in the synaptic cleft The substance tricks the neuron into releasing a flood of dopamine back in the synaptic cleft
What happens to the neuron if sodium channels do not open?
