WebThis is a reflex of proprioception which helps maintain posture and balance, allowing to keep one's balance with little effort or conscious thought. The patellar reflex is a clinical and classic example of the monosynaptic reflex arc. [3] There is no interneuron in the pathway leading to contraction of the quadriceps muscle. WebThe three major neurones involved in reflex arcs are sensory neurones, relay neurones, and motor neurones. Reflexes are rapid, protective, involuntary, short-lived, and localized. We have different types of reflexes in the body. Four key examples are the stretch reflex, the flexor reflex, the crossed-extensor reflex, and the Golgi tendon reflex. the park pc
