Närviühendus

Närviühendus, a term of Estonian origin, broadly refers to a nerve connection or neural pathway. It encompasses the physical and functional links between nerve cells, known as neurons, that allow for the transmission of information within the nervous system. These connections are fundamental to all neurological functions, from simple reflexes to complex cognitive processes.

The primary site of a närviühendus is the synapse, a specialized junction where one neuron communicates with another. At a synapse, electrical or chemical signals are passed from a presynaptic neuron to a postsynaptic neuron. This transmission is crucial for processing sensory input, generating motor commands, and forming memories. The intricate network of närviühendused constitutes the basis of the brain's circuitry and the entire nervous system's operational capacity. Disruptions or alterations in these connections can lead to various neurological disorders. Understanding the structure and function of närviühendus is a central goal of neuroscience.
