The understanding consists of about 100 billion neurons - nerve cells crucial. It is thanks to them that we reflect, feel and act.

Is twice the cells called glial cells, or simply glia neuroglejem. They sustain the structure and metabolism of neurons.

A distinctive neuron cell has an fluctuating form, and in the middle of the dim center. It is surrounded by a cell membrane with protruding from it are lanky fibrils. This dendrites - bony projections, which comes from one faction positive to 10 thousand. They resemble the branches of a tree - are thickest by the cell ascend, next single keen on thinner branches. Every collected they grow a system comparable rubbery sponge.

Dendrites do something as antennas, hear impulses from supplementary neurons and transmit them to the cell nucleus, or vice versa from the nucleus to the supplementary cells. They are fantastically unstable, level to damage, principally in the elderly. Thus, greater than period, fewer efficiently hear and transmit impulses.

In the brain, here are several types of neurons that act proceeding several parts of the body. For paradigm, motor neurons carry impulses to muscles energy, recommending the execution of the movement. Signals transferred to the endocrine glands, causing the secretion of hormones. Sensory neurons transmit sensory impulses, bountiful us information about what we distinguish, hear, feel, predilection and smell. Here are too relay memories, head and dreams.

The main of the individual filaments emergent from the cell to the axon. Reaches a length of awake to one, and up to 1.5 meters. Conducts nerve impulses to the dendrites of supplementary neurons.

Axons and dendrites have tiny twigs that connect them with supplementary neurons. From end to end these branches of a distinct chamber can make an announcement with thousands of new neurons.

Point of contact stuck between the axon of one neuron and the dendrites of supplementary neurons that synapse. It is infinitely minor connector worried. A unattached neuron can have as a lot of as 100,000 synapses, between it to supplementary cells.

Glia, the supporting cells, surrounds the axons, forming an insulating layer called the myelin sheath, or else myelin. Myelin prevents interruptions in the arise of exciting undercurrent, facilitates and streamlines the arise of regeneration calls.

The cells are contacted with each additional by resources of electrical pulses and chemical interactions. Information, that is, the electrical impulse runs along the axon to the synapse, where it causes the release of a minor portion of chemicals called neurotransmitters (neurotransmitters). Nerve cells and neurotransmitters proceed rapidly. Dispatch an electrical suggest www.kominki-renkom.pl next to the end of the axon, neurons takes only a thousandth of a second.

Neurotransmitters crisscross the synapse infinitesimal sitting room and reach the nearby neuron dendrites. In attendance activates certain receptors - protein chiefly sensitive - located in the membrane of the cell receiving the suggest. In attendance is next a reaction like to the interaction connecting the vital and the fasten. Apiece neurotransmitter concede and assign to an proper receptor. When the neurotransmitter binds to its receptor, it triggers a series of biochemical reactions that compose that information gets into the cell nucleus. At that moment it is sent by to the axon terminals and transmitted to close cells. They solve it their own neurotransmitters cells.

In minute neurons retain trials whose complexity exceeds the complexity of the production processes in the modern factory.

Thus, specific cells are neurons. Are focused in the conduction of electrical impulses and chemical. All the rage adding up, they can systematize a regional network. These, in service, tie to the regions and structures of the brain that work together as a system. The brain is a system of systems.

This composite is a flagrant account of the knotty deal with of heartbreaking to a distinct nerve impulse athwart the network. In piece of evidence, a lot of hundreds of axons creates all distinct neural outline. These, in become, bring in up the bundle build nerve bandanna of the brain - which is the superficial layer of the bark and the spinal cord.

Pulse current is not a distinct gesticulate, on the contrary a million times multiplied wave spilled all more than the residential area.

As described by the brain are transmitted belief. This arise of current amid neurons is a administer of thought. They materialize in the create of signals and reaching the proper zone of
