: Regulates autonomic functions and muscle tone during movement. 👁️ Specialized Example: The Optic Tract The optic tract is a critical part of the visual pathway.
These carry motor commands from the brain down to the muscles.
: While usually referring to nerves, the term is also used for systems like the Gastrointestinal (GI) Tract or Respiratory Tract , which are continuous tube-like structures for digestion and breathing. : Regulates autonomic functions and muscle tone during
: It carries visual information from the optic chiasm to the lateral geniculate nucleus (LGN) in the thalamus.
Understanding tracts is vital for diagnosing neurological conditions. : While usually referring to nerves, the term
: By testing which sensations or movements are lost, doctors can pinpoint exactly where in the brain or spinal cord a "tract" is damaged.
In anatomy, a is a bundle of nerve fibers (axons) within the Central Nervous System (CNS) that connects different parts of the brain or spinal cord. Unlike "nerves," which exist in the peripheral nervous system, tracts are the "highways" of the brain and spine, transmitting sensory and motor data over long distances. 🧠 Types of Neural Tracts : By testing which sensations or movements are
: Controls voluntary, skilled movements, especially of the limbs.
