What happens to the neuron if sodium channels do not open?

If sodium channels do not open, the neuron will not be able to depolarize properly and generate an action potential. This can disrupt the transmission of signals along the neuron and impair communication with other neurons. It can also affect the overall functionality of the nervous system.


What is the concentration of sodium in a neuron?

The concentration of sodium inside a neuron is lower than outside due to the activity of the sodium-potassium pump. Specifically, the concentration of sodium ions is higher outside the neuron at around 145mM, compared to around 10-15mM inside the neuron.


What happens if the presynaptic membrane of a motor neuron suddenly becomes permeable to calcium ion?

The motor end plate will be depolarized.If you found this answer for A&P then on the next unanswered question you come across once you find the answer type it in to help your fellow brothers out.The motor end plate will be depolarized.


What happens when you open the sodium channels in the membrane of a neuron?

When this occurs, the membranes potenial drops, as potassium and sodium diffuse with their gradient.


Why are sodium ions concentrated on the outside of the neuron?

Sodium ions are concentrated on the outside of the neuron due to the action of the sodium-potassium pump, which actively transports sodium out of the cell in exchange for potassium. This helps maintain the neuron's resting membrane potential and creates a concentration gradient favoring the movement of sodium into the cell during an action potential.

The neuron in your finger senses the temperature first. It sends a signal to your brain, which then interprets the information and signals your muscles to move your hand away from the heat source.

When you touch something hot a neauron in your finger senses the temperature which happens first?

The first thing that happens when you touch something hot is the activation of specialized nerve endings called thermoreceptors in your skin. These thermoreceptors detect the change in temperature and send a signal to the brain through the neuron to alert you of the heat and trigger a reflex action like pulling your hand away.


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.

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 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 during an action potential in a neuron?

During an action potential in a neuron, there is a rapid change in electrical charge across the cell membrane. This change allows for the transmission of signals along the neuron.


During an action potential, what happens to the neuron's electrical charge?

During an action potential, the neuron's electrical charge rapidly changes from negative to positive, allowing for the transmission of signals along the neuron.
