Key Concepts

Lower Motor Neurons

Lower motor neurons are the final common pathway for transmitting neural signals from the central nervous system to skeletal muscles. They receive input from upper motor neurons and directly innervate muscles, thereby executing the motor commands necessary for movement. This synaptic connection between upper and lower motor neurons is essential for proper motor function.

Upper Motor Neurons

Upper motor neurons are neurons located in the motor regions of the cerebral cortex and brainstem. They are responsible for initiating and controlling voluntary motor movements by sending signals down the spinal cord. These neurons are part of the central nervous system and play a key role in orchestrating movement by influencing the activity of lower motor neurons.
