Question 3 • Biology - SC3209 IC

What would happen to an area of the body where motor neurons are injured due to an accident?

Answer
A
increased release of neurotransmitters
B
loss of muscle movement
C
increased stimuli
D
decrease in inflammation

Explanation

Motor neurons carry signals from the nervous system to muscles, telling them when to contract. If these neurons are injured, the affected muscles may not receive those signals, causing loss of muscle movement. The injury would not generally increase neurotransmitter release or stimuli, and reduced inflammation is not the direct result.
