what is the flexor reflex?
- painful stimuli elicits it , causing withdrawal
- mediate dby polysynaptic reflex in which interneurons are excited first and then relay signal to motorneuron
- primary afferent pain fibres activate these interneurons in the grey matter, these activate alpha motor neurons that innervate flexor muslce
- flexion of more than one joint is achieved by coordinated action fo more than one spinal segment which is achieved by collateralisaton of primary affernet with interneurons
