The answer is: monosynaptic reflex.

Explanation:

  • A monosynaptic reflex is a simple reflex arc that involves only one synapse between the sensory neuron and the motor neuron. This is the most direct and fastest type of reflex pathway.
  • In this type of reflex, the sensory neuron directly synapses with the motor neuron without any interneurons involved, which is why it is called "monosynaptic" (meaning "one synapse").
  • An example of a monosynaptic reflex is the knee-jerk reflex, where tapping the patellar tendon leads to a direct response in the quadriceps muscle.

In summary, the correct term to fill in the blank is "monosynaptic."
