Gemmule, Spike (Gemmule)

A gemmule, or spine (from the English gemmule) is a small column or superficial outgrowth of a dendrite through which one neuron contacts another. Gemmules are located on the processes of nerve cells and form synapses - places where nerve impulses are transmitted from one neuron to another. The size of the gemmule is very small - only about 1 micron. Despite their size, gemmules play a key role in the functioning of the nervous system, since it is through them that information is transferred between neurons. In fact, gemmules are one of the most important structural elements that ensure the functioning of the brain and nervous system as a whole.

Introduction

Gemmules and spines are key structures involved in the process of transmitting information between neurons. They represent a small column through which electrical contact occurs between two neurons, ensure the transmission of signals between them and are a key element of the nervous system. In this article, we will look at what the gemmule and spine are, how they work, and how their disorders can affect brain function. Description

Hemodene gemmules and hemokinesis consist of membrane asymmetric tubes 30-50 µm long and 25-40 µm in diameter, connected to the cell membranes of two different neurons. Can provide transmission of short signals or direct electric current
