axon hillock การใช้

• Emerging out from the soma is the axon hillock.
• Immediately after the axon hillock is the axon.
• The loss of staining begins near the nucleus and spreads toward the axon hillock.
• The action potential generated at the axon hillock propagates as a wave along the axon.
• This depolarization will travel towards the axon hillock, diminishing exponentially with time and distance.
• The axon hillock is a specialized domain of the neuronal cell body from which the axon originates.
• The net potential is then transmitted to the axon hillock, where the action potential is initiated.
• The surge of depolarization traveling from the axon hillock to the axon terminal is known as an action potential.
• From an inhibitory perspective, excitation comes in over the dendrites and spreads to the axon hillock to trigger an action potential.
• Once this initial action potential is initiated, principally at the axon hillock, it propagates down the length of the axon.
• Nuclear eccentricity can be attributed to the presence of excess axonal cytoskeleton between the nucleus and axon hillock, which causes chromatolysis.
• The stimuli that have traveled down the dendrites converge at the axon hillock, where they are summed to determine the neuronal response.
• Ultimately it will create a new action potential at its axon hillock to release neurotransmitters and pass on the information to yet another neighboring neuron.
• The axon leaves the soma at a swelling called the axon hillock, and can extend for great distances, giving rise to hundreds of branches.
• If the sum of the stimuli reaches a certain voltage, known as the threshold potential, depolarization continues from the axon hillock down the axon.
• If several such events occur in a short time, the axon hillock may become sufficiently depolarized for the voltage-gated sodium channels to open.
• These filaments are found in greater concentrations at the axon hillock and at the beginning portion of an axon in an SGC of the sympathetic ganglia.
• This all-or-nothing phenomenon originates at the axon hillock, resulting in a depolarization of the intracellular environment which propagates down the axon.
• Action potentials begin near the axon hillock and propagate down the length of the axon, but they also propagate backward through the soma into the dendritic arbor.
• That is to say, it will create a new action potential at its axon hillock, releasing neurotransmitters and passing on the information to yet another neighboring neuron.
