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 brain and spinal cord 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 signal transmission, not increase neurotransmitter release). Increased stimuli also doesn't relate as motor neurons are for output (movement) not processing more input stimuli. A decrease in inflammation is unrelated to motor neuron function. Losing muscle movement occurs because the motor neurons can't send the necessary signals for muscles to contract and move.

Answer:

B. It loses muscle movement.
