The kneejerk reflex in response to a mallet tap over the patellar ligament

Reflex actions are very rapid, involuntary, stereotyped behaviours in which some kind of stimuli evoke a fast, short lived response. Select the correct option w.r.t. reflex actions Statement A : In a Knee-jerk reflex, more than one synapse is formed in the reflex path. Statement B : The afferent neurons in a reflex action transmit the impulses received from sensory organs via dorsal nerve root into CNS
