Hace 1 día · Neurologic Rosai–Dorfman disease (RDD) is a rare type of non-Langerhans cell histiocytosis that affects the central nervous system. Most neurologic RDDs grow like meningiomas, have clear boundaries, and can be completely resected. However, a few RDDs are invasive and aggressive, and no effective treatment options are available because the molecular mechanisms involved remain unknown. Here ...
Hace 5 días · Neurons conduct electrical impulses called action potentials. Action potentials involved in muscle contraction function to stimulate the muscle fiber. They do this by depolarizing the muscle fibers by changing the electrical, or potential difference, across their membranes. This instructs the muscle to contract. Key Term: Action Potential.
