The activation gates of voltage-gated Na+ channels open, and Na+ diffuses into the cytoplasm.
Voltage-gated Na+ channels change shape, and their activation gates open.
The "Threshold" just means the point at which something occurs, such as sound. The threshold of a sound would be the volume at which you would first start to hear the sound.

The ileocecal valve opens in response to?
The ileocecal valve opens in response to pressure from the contents of the ileum pushing against it, signaling the need for passage of undigested food material into the large intestine.
Why don't the terms depolarization and action potential mean the same thing?
Depolarization occurs when a stimulus opens sodium channels which allow more sodium to go into the membrane making it less negative and more positive (toward reaching threshold). An action potential can only occur once the membrane reaches threshold which means it has reached the level needed through depolarization. An action potential is a brief reversal in polarity of the membrane making the inside more positive and the outside more negative, the reverse occurs again once the membrane reaches resting potential.
Which statement correctly describes what causes the second voltage-gated Na plus channel to open?
The second voltage-gated Na+ channel opens due to the membrane potential of the neuron becoming further depolarized beyond its threshold level. This depolarization causes a change in the conformation of the channel's protein subunits, allowing the flow of Na+ ions into the neuron.

Describe azucenas situation when the story opens?
Azucena is a victim in a volcanic eruption when the story opens.
What opens first in response to a threshold stimulus?
Voltage-gated sodium channels open first in response to a threshold stimulus. This allows an influx of sodium ions into the cell, causing depolarization and generation of an action potential.
What is the relationship between a stimulus and a response?
A response is always triggered by a stimulus. One example is in a neuron (nerve cell). Once a sensory stimulus is witnessed (a stimulus from one of the 5 senses), the cell hits an action potential, and the response is carried out. Simply put: A human eye is closed. Once the eye opens thousands of sensors in the eye pick up the photons bouncing off all objects (stimulus), and the human is able to see (response).
The ileocecal valve opens in response to?
The ileocecal valve opens in response to pressure from the contents of the ileum pushing against it, signaling the need for passage of undigested food material into the large intestine.
How can the level of pain you feel vary if a stimulus casues an all-or-none response?
Even if a stimulus triggers an all-or-none response, the level of pain experienced can vary depending on individual differences in pain perception, tolerance, and other factors like emotional state or context in which the pain occurs. Each person's perception and experience of pain can be influenced by a variety of factors beyond just the specific stimulus.
What is the flehmen response?
