Question
Most of the fibers of the lateral corticospinal tract cross over in the medulla oblongata.
True / False
Solution
Answer:
True
The majority of the fibers of the lateral corticospinal tract do cross over (decussate) in the medulla oblongata. Specifically, this crossover occurs at the pyramids, which are located in the lower part of the brainstem. After the decussation, the fibers continue down the spinal cord on the opposite side, ultimately influencing motor control on the contralateral side of the body. This anatomical feature is crucial for coordinating voluntary motor movements and is a key concept in understanding the neuromuscular pathways in the central nervous system.
