What is the basic difference between a local homeostatic response and a reflex?
Reciprocal inhibition between reflexes depends upon all the following,except :-a- presence of inhibitory interneurons in the reflex pathwaysb- presence of excitatory interneurons in the reflex pathwaysc- presence of anion channels in membranes of the involved neuronsd- release of inhibitory transmitters which block cation channels in the reflex pathways
rank the components of a reflex arc in the correct order
