Question
Match each type of cerebral medulla fiber tract with its function.
- Commissural fibers
- Projection fibers
- Association fibers
Solution
-
Commissural fibers: These fibers connect the two hemispheres of the brain. They allow for communication between the two sides. The most prominent group of commissural fibers is the corpus callosum.
-
Projection fibers: These fibers connect the cerebral cortex to the lower brain regions and the spinal cord. They carry information between the brain and the rest of the body. They include both afferent (sensory) and efferent (motor) fibers.
-
Association fibers: These fibers connect different regions within the same hemisphere of the brain. They are responsible for integrating information from different parts of the brain. They can be short, connecting adjacent gyri, or long, connecting different lobes of the brain.
