Explanation:
Detailed explanation-1: -The Myotatic Reflex Is a MonoSynaptic Reflex Between Ia Afferents and the Motor Neuron. The myotatic reflex is the “knee-jerk” reflex in which a muscle contracts in direct response to its stretch.
Detailed explanation-2: -Monosynaptic reflexes include, for example, the biceps and triceps reflexes, and patellar stretch reflex or knee jerk (see figure below). In contrast, polysynaptic reflexes are mediated through at least two synapses and one interneuron.
