närvifunktsioon

Närvifunktsioon refers to the process by which nerve cells, also known as neurons, transmit information. This fundamental biological mechanism underlies all aspects of nervous system activity, from sensory perception and motor control to thought and emotion.

The transmission of information within a neuron occurs via electrical signals called action potentials. When a neuron is stimulated, it generates an electrical impulse that travels down its axon, a long projection. At the end of the axon, the electrical signal is converted into a chemical signal.

This chemical signal is transmitted across a small gap called a synapse to another neuron or target cell. The chemical messengers involved are known as neurotransmitters, which bind to specific receptors on the receiving cell, either exciting or inhibiting its activity. This intricate interplay of electrical and chemical signaling allows for complex communication networks within the brain and throughout the body.

Disruptions in närvifunktsioon can lead to a wide range of neurological disorders, affecting various bodily functions. Understanding these processes is crucial for diagnosing and treating such conditions and for advancing our knowledge of the nervous system.
