What will be the result if the motor nerve is damaged?
Answer and explanation
Correct answer: The message will not properly reach the muscle
The governing concept is the direction of impulse conduction. A motor nerve, or motor neuron pathway, carries commands from the brain or spinal cord to an effector such as a muscle. If this nerve is damaged, the receptor may still detect the stimulus and the central nervous system may still form a command, but the command cannot reach the muscle effectively. Therefore option C is correct. A concerns sensory reception, while B and D have no logical connection with motor-nerve damage.
