If reciprocal innervation failed during a stretch reflex, the consequence might be that
A) the overall movement would be diminished due to opposing muscles contracting simultaneously.
B) the overall movement would be exaggerated due to the lack of regulation from opposing muscle contraction.
C) the complete loss of movement due to lack of stimulation of the effector muscle.
Reciprocal Innervation
A neurological process where the activation of one muscle is accompanied by the relaxation of its antagonist muscle.
Stretch Reflex
A muscle reflex that responds to the stretching within the muscle, automatically contracting the muscle in response to its stretching in order to protect the muscle from over-stretching.

Final Answer :
A
Explanation :
Reciprocal innervation ensures that while one muscle contracts, its opposing muscle relaxes, allowing for smooth movement. If this mechanism fails, both the muscle and its antagonist might contract simultaneously, leading to diminished movement.
