The axon hillock neuron first proposed by Carver Mead [37] integrates an input current on a capacitor and outputs a voltage spike upon crossing a threshold. The circuit shown in Fig. 9 implements

The axon hillock and axon differ from the soma and proximal dendrites in that they lack rough endoplasmic reticulum, free ribosomes, and Golgi apparatus. The

Axon hillock

Tusentals nya, högkvalitativa triggas en aktionspotential som fortleder längs axonet ända ut till synapserna. På sin väg till synapserna summeras i den region som kallas Axon Hillock. Axon, aksoni, axon. I nervcellerna finns vanligtvis endast en axon. Axonen utgår från en pyramidformad upphöjning på nervcellkroppen (eng. axon hillock). Axon.

axon hillock A conical protuberance that surrounds the axon at its point of departure from the neuronal body, at which point Nissl substance is minimal and accompanied by specialised plasmalemma. Segen's Medical Dictionary. © 2012 Farlex, Inc.

The axon leaves the soma at a swelling called the axon hillock, and can extend for great distances, giving rise to hundreds of branches. Akson zostawia somę przy opuchliźnie nazwanej wzgórek włókna osiowego, i móc poszerzać dla wielkich odległości, dając początek sto gałęzi.

It is a town of above three hundred houses, built round the base of a sandy hillock, the church being on the hill. Travels through the South of France and the Interior of Provinces of Provence and Languedoc in the Years 1807 and 1808 | Lt-Col. Pinkney

The axon initial segment is not protected by the o Axon – lång utlöpare: specialiserad på snabb fortledning av. nervimpulser över stora avstånd. Främre delen kallas för axon hillock. (här finns initialsegmentet) First segment of axon that connects distal axon segments to the neuronal CELL BODY at the axon hillock region. The axon initial segment is not protected by the Talrika exempel på översättningar klassificerade efter aktivitetsfältet av “axon hillock” – Engelska-Svenska ordbok och den intelligenta översättningsguiden. De mest effektiva synapserna är de som befinner sig närmast axon hillock. Inhibitatoriska synapser befinner sig därför ofta på soman för att ge störst effekt.

The Axon hillock. this region (first part of the axon) receives local signals (graded potentials) from the soma and dendrites and has a high concentration Axon Hillock. Also known as the axon initial segment or “trigger zone”, the axon hillock is the region of the axon closest to the soma.

The arrow labeled "axon" is pointing directly at the axon hillock. 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 accumulate.

One Motor Axon Goes To. The axon hillock is a specialized part of the cell body of a neuron that connects to the axon. It can be identified using light microscopy from its appearance and location in a neuron and from its sparse distribution of Nissl substance. The axon hillock is the last site in the soma where membrane potentials propagated from synaptic inputs are summated before being transmitted to the axon. For many years, it was believed that the axon hillock was the usual site of initiation of action The axon hillock is a unique area within neurons because of its ability to process the incoming signals from other cells.
