The junction between an axon and its cell body; where action potentials are generated.
is the site at which the axon originates from the neuronal cell body, and is in continuity with the initial segment of the axon. This is the most excitable part of a neuron as a result of its high density of sodium channels and is therefore the site of initiation of the action potential
swelling at the cell body when axon begins. Then the axon maintains constant diameter down its entire length. The impulse is carried from the cell body toward the axon terminal to other cells (generally).
The region of the axon closest to the cell body where the action potential often originates.
The implantation cone, an area of the protoplasm of a neuron from which the axon arises. It contains no tigroid substance.
The cone shaped region at the junction of the axon and cell body
the transitional region between an axon and the nerve cell body
In a multipolar neuron, the portion of the cell body adjacent to the initial segment.
The portion of the axon where the axon leaves the soma. It is here that spatial and temporal summation occur and the action potential begins.
The Axon Hillock is the anatomical part of a neuron that connects the cell body called soma (biology) to the axon. It is attributed as the place where Inhibitory Postsynaptic Potentials (IPSPs) and Excitatory Postsynaptic Potentials (EPSPs) from numerous synaptic inputs on the dendrites or cell body summate.
