Answer #1

This mechanism is called reflex action

when a fly lands on the foot, it acts as a stimulus.

The reflex pathway comprises at least one afferent neuron (receptor) and one efferent (effector or excitor) neuron appropriately arranged in a series. The afferent neuron receives signal from a sensory organ and transmits the impulse via a dorsal nerve root into the CNS (at the level of spinal cord). The efferent nueuron then carries signals from CNS to the muscles in the foot. and then we shake our foot to fly off the fly
