The lateral reticulospinal tract is a pathway in the central nervous system that originates in the reticular formation of the brainstem. It plays a crucial role in regulating voluntary movements and muscle tone, particularly in the limbs. This tract helps coordinate movements by influencing motor neurons in the spinal cord. This tract is part of the extrapyramidal system, which is involved in the control of posture and locomotion. It primarily facilitates the activity of flexor muscles while inhibiting extensor muscles, allowing for smooth and coordinated movements. Dysfunction in this tract can lead to motor control issues.
