Axon, aksoni, axon - solunetti

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 potentials—the trigger zone. axon hillock (suomeksi) Määritelmät: (lb, en, biology) A specialized part of the soma of a neuron that connects to the axon. It is the last site in the soma where membrane potentials propagated from synaptic inputs are summated before being transmitted to the axon. Start studying A&P I Chapter 11 Lab.

The proximal part of the axon, adjacent to the axon hillock, is the initial segment. The cytoplasm of the axon (axoplasm) contains dense bundles of microtubules and neurofilaments (Figs. 2.1 and 2.5A, B). These function as structural elements, and the microtubules also play key roles in the transport of metabolites and organelles along the axon. The axon hillock is situated between the cell body and the axon. Electrical impulses from the dendrites and cell body are summed at this point, which then can send an action potential down the axon. The body of a neuron has dendrites sticking out of all sides.

Electrical impulses from the dendrites and cell body are summed at this point, which then can send an action potential down the axon. The body of a neuron has dendrites sticking out of all sides. On one end, it has a long tail, called an axon, which ends in the terminal buttons. 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.
