  The Patellar reflex is an example of a somatic reflex. This refers to the branch of the nervous system that the reflex pertains to. The somatic branch is part of the Per â¦ ipheral Nervous system meaning that it's reflex arc does not pass through the central nervous system (the spinal cord and the brain).
When the physician taps the patellar tendon with a hammer, this action causes the knee extensor muscle to stretch abruptly. This stretch activates the myotatic reflex, causing an extension of the lower leg. (Because the physician taps the tendon, this reflex is also referred to as the deep tendon reflex.ust as in the stretch reflex, the autogenic inhibition reflex must coordinate the activity of the extensor and flexor muscle groups (Figure 2.4). The Ib afferent fiber bifurcates in the spinal cord.
