Study Notes
Fine Voluntary Movement and Muscle Tone
- The cerebellum plays a crucial role in controlling fine voluntary movements and regulating muscle tone.
Descending Tract in the Pyramidal System
- The corticospinal tract is a primary descending tract within the pyramidal system, essential for voluntary motor control.
Old Term for the Pons and Medulla
- The term bulb is historically used to describe the pons and medulla, which are vital structures in the brainstem.
Postural Reflexes and Muscle Tone Pathway
- The extrapyramidal system is responsible for regulating postural reflexes and maintaining muscle tone.
Tract Visualized by Diffusion Tensor MRI
- The corticospinal tract can be visualized using diffusion tensor MRI, which aids in studying pyramidal decussation, where motor fibers cross over to the opposite side of the body.
