Question

what happens to the body when motor neurons are injured?
○ it releases more neurotransmitters.
○ it loses muscle movement.
○ it experiences increased stimuli.
○ it shows a decrease in inflammation.

Explanation:

Motor neurons are responsible for transmitting signals from the central nervous system to muscles to initiate movement. If motor neurons are injured, the communication between the nervous system and muscles is disrupted. Releasing more neurotransmitters is not a typical result of motor neuron injury (injury would likely impair neurotransmission, not increase it). Increased stimuli are not related to motor neuron function (motor neurons deal with output to muscles, not processing incoming stimuli). A decrease in inflammation is also not directly related to motor neuron injury (injury might cause inflammation or not directly affect its decrease). So, when motor neurons are injured, the body loses muscle movement as the signals to move muscles are impaired.

Answer:

B. It loses muscle movement.
