Pathways in the Central Nervous System

Overview

Neural pathways transmit information between the body and the brain, enabling sensation, movement and conscious perception. This section outlines the major motor, sensory and special sensory tracts.

Key Structures

Topics include ascending pathways, descending pathways, the visual pathway and the auditory pathway. Each article describes the route, key synapses and functional significance of these tracts.

Clinical Relevance and Learning Focus

Knowledge of neural pathways is essential for interpreting patterns of sensory loss, motor deficits and visual or auditory disturbances. This section supports localisation of lesions and systematic neurological assessment.
