A patient sustained an injury to the lower motor neurons when a board fell on his back at a construction site. The upper motor neurons are intact and undamaged. Determine the effect, if any, on motor control
What will be an ideal response?
The upper motor neurons stimulate the lower motor neurons. Since they sustained damage, the lower motor neurons will be unable to stimulate affected skeletal muscles to contract. This patient will experience weakness or paralysis of the affected muscles and loss of reflexes since the lower motor neurons are damaged.
