Motor Pathways and Their Role in Movement Control
Understanding the Extrapyramidal Tracts
The human nervous system comprises multiple motor pathways responsible for initiating, coordinating, and regulating movement. Among these, extrapyramidal tracts play a crucial role in posture and muscle tone.
Components of Extrapyramidal System
- Reticulospinal tract
- Vestibulospinal tract
- Rubrospinal tract
- Tectospinal tract
These tracts influence involuntary movement and postural stability, ensuring smooth motor control.
Functions and Clinical Significance
Extrapyramidal tracts modulate reflexes, balance, and coordination. Dysfunction of this system is often linked to neurological disorders such as Parkinson's disease and Huntington's chorea.
