What is the point of the Axon Hillock in a neuron? : r/askscience
2014年1月2日 · The Axon Hillock is the area (where is was thought) there is the greatest number of these channels. If the postsynaptic depolarisation is sufficient to depolarise the membrane in the area of the Axon Hillock above a trigger threshold then all the voltage gated channels at the Hillock can open.

Part of neuron that gives rise to axon collaterals D. Part of neuron that stores neurotransmitters E. Endoplasmic reticulum of the
Solved A neurotoxin binds and disables a type of ion channel
Science; Anatomy and Physiology; Anatomy and Physiology questions and answers; A neurotoxin binds and disables a type of ion channel at the axon hillock, preventing depolarization of the axon hillock and axon.
Solved Pathway #2) An action potential initiates at the axon - Chegg
Pathway #2) An action potential initiates at the axon hillock of a postsynaptic neuron. Describe the sequence of events within a postsynaptic neuron that initiates an action, including formation of a postsynaptic potential via an Ionotropic Chemical Synapse within the dendrites and the subsequent of events involved in the first cycle of an action potential generated at the axon …
Solved Why is an action potential conducted in only one - Chegg
Why is an action potential conducted in only one direction, from an axon hillock to an axon terminal? The number of voltage-gated ion channels increases along the length of the axon. The membrane channels upstream are refractory and cannot open. The channels are progressively easier to open down the length of the axon. Second messengers activate
