Final answer:
Reciprocal innervation is exemplified by the withdrawal reflex, where stimulation of the nerve supply to one muscle and inhibition of its antagonist muscle allows for faster withdrawal from a painful stimulus and prevents further tissue damage.
Step-by-step explanation:
An example of a connection involving stimulation of the nerve supply to one muscle and simultaneous inhibition of the nerves to its antagonist muscle is the withdrawal reflex. In this reflex, when a painful stimulus is detected by a sensory neuron, the interneuron in the spinal cord inhibits the motor neuron that controls the antagonist muscle, causing it to relax. This allows for faster withdrawal from the painful stimulus and prevents further tissue damage.
