Solved Which is TRUE about the axon hillock of an axon?Which
网页Which is TRUE about the axon hillock of an axon? It contains abundant voltage - gated ion channels. Synapses far from the axon hillock are more effective in influencing whether an action potential will be generated in the axon than are synapses close to the axon hillock. It can only conduct graded potentials because it lacks voltage - gated Na ...
Solved Pathway #2) An action potential initiates at the axon - Chegg
网页Anatomy and Physiology questions and answers. 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 ...
Solved A neurotoxin binds and disables a type of ion channel

Solved Describe the steps of a graded potential and explain - Chegg
网页Describe the steps of a graded potential and explain how summation occurs at the axon hillock. Include the following in your answer: voltage-gated Na+ channels, axon hillock, ligand-gated channel, dendrite, threshold voltage, EPSP, IPSP, cell body, neurotransmitter, action potential. There are 2 steps to solve this one. A graded potential is a...
Solved Summation of postsynaptic potentials at the axon - Chegg
网页Summation occurs when two or more postsynaptic potentials overlap in time; that is, one postsynaptic potential begins before the membrane has returned to resting potential after a previous postsynaptic potential. When such overlap occurs, the membrane potential measured at the axon hillock is the sum of the two (or more) overlapping ...
What is the point of the Axon Hillock in a neuron? : r/askscience
网页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.
