The oligodendrocytes belong to the group of glial cells and, along with astrocytes and neurons, are an integral part of the central nervous system. As glial cells, they perform supporting functions for the nerve cells. Some neurological diseases
The visual pathway is understood to be special somatosensitive fibers that run from the retina of the eye to the visual cortex of the brain. The complex structure of the visual pathway enables human vision.
The auditory pathway consists of special somatosensitive fibers that transmit the recorded impulses from the organ of Corti to the primary and secondary auditory cortex of the cerebrum. First instant of the auditory pathway are the sensory cells of the auditory sense, which convert sound into electrical
