Knee jerk reflex diagram. What are the steps in a knee-jerk reflex arc? - The Handy ... There are five steps in a knee-jerk reflex arc as follows: A tap on the patellar tendon (tendon attached to the kneecap) is sensed by stretch receptors in the muscle (muscle spindles). Reflex Action - Definition, Process and Examples Reflex action is a sudden and involuntary response to stimuli. It helps organisms to quickly adapt to an adverse circumstance that could have the potential to cause bodily harm or even death. Pulling our hands away immediately after touching a hot or cold object is a classic example of a reflex action. 2. Briefly state the event that proceeds a ... Reflexes: Meaning, Types, Diagram & Examples I StudySmarter Another common example of this reflex is the knee jerk reflex. Doctors do this test on patients to test that specific spinal cord segments are working. It involves striking a tendon near the knee (called the patellar tendon) with a rubber hammer. This will cause the patellar tendon to pull on the leg's quadriceps muscle (the effector).

Muscle Stretch Reflex - Reflex Arc Components ... A monosynaptic reflex, such as the knee jerk reflex, is a simple reflex involving only one synapse between the sensory and motor neurone. The pathway starts when the muscle spindle is stretched (caused by the tap stimulus in the knee jerk reflex). The muscle spindles are responsible for detecting the length of the muscles fibres.
