Detailed explanation-1: -This response is called a spinal reflex. Dysfunction of peripheral nerves may result from damage to any part of the nerve: Axon (the part that sends messages) Body of the nerve cell.

Detailed explanation-2: -Spinal cord reflexes are simple behaviors produced by CNS pathways within the spinal cord. The spinal stretch reflex (SSR), also called the knee jerk or M1, is the initial response to sudden muscle stretch.

Detailed explanation-3: -A reflex arc is a connection between perceiving the signal from the nerves and promptly responding to it. In a reflex action, the brain plays no part. The spinal cord, which reacts without thinking about how to respond to stimuli, is in charge of these automatic actions. It elicits no meaningful response in the brain.

Detailed explanation-4: -A stimulus is a change in the environment. Sometimes we control these responses consciously, with our thoughts. Other times, they happen automatically, or without thinking. A response to a stimulus that occurs without the need for conscious thought is called a reflex.
