The example of a stretch reflex triggered by passive muscle movement is the

Answer 1

Passive muscle movement is the movement of muscle made by an external source not the muscle itself. This type of movement is done on muscles that are inactive due to any accident or medical condition.

Stretch reflex is the contraction of muscle cause by a stretch within the muscle. It is also known as myotatic reflex. 

An example of stretch reflex triggered by the passive muscle movement is Patellar Reflex. Patellar reflex is the movement in the lower leg caused by a sharp tap on the patellar tendon. It is a muscle under the kneecap. 

Answer 2

An example of stretch reflex triggered by the passive muscle movement is Patellar Reflex. Patellar reflex is the classical example of monosynaptic reflex arc. In patellar reflex there are no interruptions in the pathway which basically leads to contraction in the quadriceps muscle in the body of the organism. Here the bipolar sensory neuron synapses directly on a motor neuron in the spinal cord.
