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, enabling movement. If they are injured, the signal transmission is disrupted.

• Releasing more neurotransmitters is not a direct consequence of motor neuron injury. Neurotransmitters are chemical messengers, but injury would likely affect their normal release pattern rather than increasing it in a beneficial way for movement.
• Motor neurons control muscle movement. When injured, the muscles do not receive the proper signals to contract and relax, leading to loss of muscle movement.
• Increased stimuli are not related to motor neuron injury. Motor neurons are about sending signals for movement, not about the body experiencing more stimuli in general.
• A decrease in inflammation is not a typical direct result of motor neuron injury. Inflammation might occur as a secondary response in some cases (e.g., due to trauma that caused the injury), but it's not a direct effect on muscle - movement - related functions.

Answer:

It loses muscle movement.
