Question

During a patellar tendon (knee-jerk) reflex, muscle spindles detect stretch in the quadriceps and generate a reflex that cause the quadriceps to contract and extend the leg. At the same time, the hamstrings relax, allowing the leg to extend. The hamstrings relaxing is an example of __________. initiating a crossed extensor reflex. initiating a stretch reflex. initiating a tendon reflex. the process of reciprocal inhibition.
