Polysynaptic Reflexes
Most of the reflexes are polysynaptic
Sensor is remote from effector
autonomic reflexes, polysynaptic somatic reflexes.

Characteristics of polysynaptic reflexes, ex: coughing a) presence of delay period
b) Summation of the subthreshold stimulus in central neurons & motorneurons of the reflex arc.
c) Reflex time & intensity of response depend on the stimulus intensity.
d) plasticity of the reflex response, habituation, dishabituation, sensitization, conditioning (long-term changes in the reflex response)
