MEDICAL PHYSIOLOGY

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: -Sudden reaction in response to the stimulus is known as a reflex action.

Detailed explanation-3: -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-4: -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.

Detailed explanation-5: -Reactions are voluntary responses whereas reflexes are involuntary or unintentional (and not subject to conscious control in most cases). Each type of response is initiated by a sensory stimulus that may be visual, audible, tactile, olfactory, or gustatory in nature.
