The human nervous system (Latin systema nervosum) – a system built of nerve tissue and glial tissue, integrating the body’s activity, recording stimuli, processing the information contained in them and controlling the body’s activities: muscle movement and hormone secretion.
Peripheral nervous system activities can be conventionally divided into two categories:
The somatic nervous system (Latin soma – body) focused on communication with the outside world, receives various information from it via the sense organs and manages the locomotor apparatus, enabling it to move in space and respond in a targeted manner to external stimuli.
Autonomic or vegetative nervous system (Latin: autos – self and nomos – law, and therefore “self-governing”) – its role is to control metabolism and the proper functioning of internal organs.
The activities of both these systems are coordinated on the upper floors of the nervous system.
The basic element of the nervous system is a nerve cell with protrusions protruding from it, called a neuron.
The neuron consists of a bulbous cellular body with a nucleus (perikarion) and numerous protrusions protruding from the body. These projections form tree-like branches known as dendrites. One of the protrusions is much longer than the others, covered with a light myelin sheath and it is called a neurite or axon. The length of the axon can reach up to 1 meter.
Neurons contact each other via links, called synapses. Their number is many times greater than the number of nerve cells, because each protrusion creates many synaptic contacts with other nerve cells.
Neurons create synapses not only with nerve cells, but also with other types of cells (e.g. muscle cells, sensory organs).
The human central nervous system consists of about 100 trillion synapses, 10-15 billion neurons and 140 billion glial cells.
The main task of neurons is receiving, processing and transmitting information in the form of electrical stimuli. Each nerve cell receives information transmitted from other neurons, as well as from other specialized cells – receptors of sensory organs, or directly from the external environment by specialized dendrites. This information is forwarded by the cell via axon. Information transmitted and processed in neurons is encoded in the form of electrical or chemical signals. The axon myelin casing plays an important role in this process. It is made of lipids and acts as an insulator. Electric charges are accumulated on both sides – negative charges (anions) on the inside, and positive cations on the outside. The cell is polarized, and the potential difference on both sides of the membrane is called membrane potential. At rest, this potential is between 50 and 100 mV.
The myelin sheath is not an absolute insulator, however, because of complex physicochemical phenomena, ions may pass and the potentials will be equalized on both sides of the membrane. This phenomenon is called neuronal depolarization.
These local changes in potential form the basis of nerve cell function. The potential increases quickly, and then returns to the initial state with varying speeds – this is the so-called action potential.
The shifting of action potential caused by a stimulus is the essence of information transfer. The speed with which this process occurs varies in different axons and ranges from 4 to 400 km / h.
An important feature of axonal conduction is that the action potential does not lose strength or expire during its journey.
The way the signals are transmitted throughout the entire nervous system is the same, and the type of information and orders are read depending on which neurons or groups of neurons are excited.
Neurons transfer not only stimulation but also its strength. The stimulus strength is translated into the frequency of nerve impulses. Weak stimuli cause low-frequency pulses (several pulses per second) and strong stimuli – high-frequency pulses (several hundred per second).
Another type of phenomenon occurs when the stimulus comes to the synapse. The axon of the stimulus transmitting neuron does not come into direct contact with the body of the stimulus receiving cell, but there is a gap of 10-15 nanometers between them. The nerve stimulus overcomes this gap through a special chemical conveyor. This conveyor, called a mediator, is released in a minimal amount at the end of the axon and causes an excited or inhibited state in the cell membrane of the neighboring cell.
Differences between the propagation of the stimulus in the axon and stimulation propagating in the synapse
Axon stimulation is a phenomenon described in “all or nothing” physiology, in which the stimulus, if it is strong enough, always triggers the same reaction, if it is too weak, it is not even able to initiate a reaction.
At the synapse, each incoming stimulus causes a transition to the other side of the synaptic cleft of a certain portion of the chemical mediator. Synapses only signal in one direction – from the axon of one cell to the dendrite of the other.
The equilibrium is ensured by the fact that the cell body and its dendrites have many axon endings and rarely the neuron is stimulated by a stimulus coming from only one, the incoming signals add up. Thanks to this system, the destruction of several nerve cells does not interfere with their activities, because their role is taken over by neighboring cells (parallel channels).
