The axon mound is part of a nerve cell. A nerve cell, also called Neuron called, has the task of transmitting signals that are sent to it to the next nerve cell or to a muscle.
The Nerve cell consists roughly of three sections. The central point is the Cell body, the so-called Soma. Here is the one Cell nucleuswhich contains the genetic information of the cell. On one side they open Dendrites into the cell body. This is where the information that is passed on from other cells arrives in the form of electrical impulses.

Several cells can forward their signals to one cell. So often are many dendrites necessary to record all signals. They are passed on via the cell body and via the Axon, which is often divided into many terminal branches, to the next cell forwarded.
The axon mound is that Place of origin of the axon. He is also called Cone of origin designated. It is called a hill because this initial part of the axon is thicker than the rest of the axon.

$config[ads_text2] not foundThe Axon mounds is responsible for that of the many signals sent to a single one Nerve cell arrive, only one Collective signal about the Axon is forwarded.
There come stimulating and inhibiting signals that as inhibitory (inhibitory) or excitatory (exciting) postsynaptic potential are designated.
Be on the axon mound these signals added up. The inhibiting ones are withdrawn from the exciting ones. The Sum of all signals will then be forwarded. If as many exciting as inhibiting signals arrive, it leads to one Extinguishing the signal, so nothing is passed on.
The nerve cell is on the axon hill particularly sensitive for receiving signals.
The summation of all incoming signals leads to one exciting signal, there is a change in the composition of various tiny particles (the Ions). This leads to a electrical activitywhich is transmitted through the entire axon to the next cell.
