Lower motor neurons

Lower motor neurons are nerve cells located in the spinal cord and brainstem that directly control muscles. They receive signals from the brain and transmit these signals to muscles, facilitating movements like walking, grasping, or smiling. When lower motor neurons are damaged, it can lead to weakness or paralysis in the affected muscles, impacting movement and coordination. Their proper function is essential for everyday tasks, and understanding them helps highlight their critical role in the nervous system and muscular activity.
