When a person accidentally … WebAn action is an involuntary response to a stimulus. A reflex is made possible by a neural pathway called the reflex arc. Whenever a sense organ senses any danger (stimulus). The sensory neurons pick up signals from the sensory organ and send them to the spinal cord. It is then received by the neurons in the spinal cord.
WebReflex arc is a neural pathway that controls the reflex action. It is a pathway followed by nerves which carry sensory from the receptor to spinal chord and then carry the response of the spinal chord to the effector organs during a reflex action. WebReflex responses also include autonomic actions such as modifications to heart rate, breathing and pupil accommodation; A common example of a reflex action is the patellar reflex (‘knee jerk’ response) that occurs when the patellar tendon is tapped. The patellar reflex is a common test employed by doctors to determine the presence of spinal ...
