The _______________ (C) receives signal from a ________________ (B) and transmits the impulse via a ________________ (D) into the CNS (at the level of spinal cord). The __________________ (E) then carries signals from CNS to the _________________ (F). The _________________ (A) and ________________ (K) thus forms a reflex arc as shown below in the ________________ reflex.
