Dendrite

Dendrites are one or more tree-like branching processes of neurons that play an important role in the transmission of nerve impulses. They are specialized structures that provide contact with other neurons and facilitate information processing in the brain.

Dendrites have many functions, including receiving, processing, and transmitting information between neurons. They are also involved in the formation of synapses - special connections between neurons that allow the transmission of electrical impulses between them.

Dendritic processes can come in different shapes and sizes, depending on the type of neuron and its function. For example, dendrites in the visual system may be star- or cone-shaped, while dendrites in auditory neurons may be curved or spiral-shaped.

An important feature of dendrites is their ability to amplify and process information. They can amplify and filter incoming signals, allowing the neuron to receive only those signals that suit its needs.

Overall, dendrites play a key role in brain function and are an integral part of the nervous system. They mediate the transmission of information and interaction between neurons, making them an important object of study in neuroscience and neurobiology.



Dendrite (from ancient Greek δένδρον - tree), or dendrocyte, or tree-like cytoplasm, more often - a bipolar neuron - consists of an axial cylindrical part, called the trunk, on which cellular outgrowths are located, which give the name to the entire organ.

In Greek, the word "dendron" means "tree", and indeed this shoot is somewhat reminiscent of a tree branch. These processes, consisting of the remains of the body of the embryo, have a different number of branches. All this gave the name “dendrite”. In Latin, the name of the process sounds like “dendriticus” - needles



Dendrites (from ancient Greek δένδρον - tree) are long branching processes of nerve cells that perform a conducting function in the central nervous system of animals and humans. Translated from Greek, “dendrite” means “tree-like.”

A dendrite is part of a neuron. Many people mistakenly believe that nerve cells are bipolar, that is, they contain two types of processes: long dendrites and a short axon. In fact, all nerve cells, without exception, have only one long process - the axon and many small branching dendrites. The number of branches varies among dendrites. They can have different lengths, thicknesses and shapes, but they all grow in different directions. Thus, each dendrite receives signals from the outside and sends them to the body of its neuron or transmits them to other neurons.

Dendrites are formed by a biochemically active substance - a special DNA-encoded ribonucleic acid - ribosomes. The entire dendrite consists of a spiral substance. Its function is to transport impulses. Pulses are special molecular “signals”. They usually cause many reactions within the dendrite along its biochemical pathways. When a nerve impulse arrives at the end of a dendrite, it spreads along all the veins of the dendrite to its main body. Certain types of nerve impulses lead to the production of, for example, protein. This allows the dendrites to be guided to the substrate with specific information. The larger the dendrite, the higher the probability that a certain sequence of nucleotides corresponds to a signal that converts it into an effect. It's more reliable. One special function of the dendrite is the formation of synapses.
