A reflex arc is a nerve pathway in the body of humans and some animals that connects certain muscle groups to others, without involving the brain. These sorts of pathways primarily control involuntary movements in response to some sort of stimulus.
The stretch reflexes (often called deep tendon reflexes, though not to be confused with Golgi tendon reflexes) provide information on the integrity of the central nervous system and peripheral nervous system.Generally, decreased reflexes indicate a peripheral problem, and lively or exaggerated reflexes a central one. reflex action, differently known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus.
