Why do nerve signals reach body parts through specific paths?
Answer and explanation
Correct answer: Nerves form fixed paths in the body
The governing concept is the organization of the nervous system. Neurons join to form connected pathways, and an impulse travels from a receptor through sensory neurons and processing centres to a particular motor neuron and effector. This wiring directs the message to the required body part. Hormones do not block nerves, blood does not create impulses, and muscles do not receive light; therefore option A is correct.
